The featured image above is a rather grainy image of steam at Drap-Cantaron Railway Station.
In the first six articles about the line from Cuneo to the sea we covered the length of the line from Cuneo to Breil-sur-Roya and then to Ventimiglia. These articles can be found here, [9] here [10] here, [11] here, [12] here, [13] and here [14]
Woven into the text below are a series of stills from a video of the train journey from Breil-sur-Roya to Nice. The video can be seen here. [4]
This article begins the journey from L’Escarene.
Initially, the line heads Southeast but then gradually turns to the the Southwest through Peille, Peillon and Drap before running into Nice.
The map below shows the two routes which headed from Nice and Ventimiglia North to Cuneo, as they existed prior to the alteration of the border between France and Italy after the Second World War.
The lines Nice to Tende and Ventimiglia to Tende in the period from 1928 to the Second World War, before the annexation, in 1947, of St-Dalmas de Tende and Piene to France. [15]
From l’Escarene to Drap-Cantaron
The line from L’Escarene to Drap/Cantaron. [25]
L’Escarene sits at the head of a long climb from Nice, it was one of the historic staging posts on the old royal road from Nice to Turin. Like Sospel Station, that of l’Escarene has substantial facilities which would allow the reception of military convoys in the event of conflict with neighbouring Italy. [1: p92]
It is only a very short distance to the abutment of the viaduct that carries the line through l’Escarene.
The D2566 passes West-East under the railway and then curves round to join the D2204 and pass North-South under the West end of the railway viaduct. The Anc. Rte de L’Escarène passes through the first arch of the viaduct. The D2204 passes through the second arch of the viaduct. [Google Maps, September 2025]
Setting off from l’Escarene Railway station, this is the first view of the l’Escarene Viaduct from the cab of a Nice-bound train. The viaduct over the Redebraus has eleven 15 metre arches. [4]
Part way across the viaduct the camera in the cab of the Nice-bound service picks up the metal parapet rails of the viaduct and the short tunnel ahead. [4]
The tunnel at the Southeast end of l’Escarene Viaduct is the Tunnel de Brec (382 metres in length. [19]

The next feature on the line is a short tunnel – Tunnel d’Euira (63 metres in length). [32]
Tunnel d’Euira is on the right side of this satellite image. [Google Maps, September 2025]
The North portal of Tunnel d’Euira. [32]
The South portal of Tunnel d’Euira and the galleried retaining structure which carries the line from a point very close to the tunnel portal. [32]
From many an angle, you would be forgiven for thinking that the railway crosses a viaduct. It appears, however, that the structure is a galleried retaining structure which creates a platform for the railway to run on while limiting the wight of the structure on the rock face beneath. [Google Maps, September 2025]
This view of the location from a little further ‘South, shows that the trackbed abuts the rockface on the East side of the line. [32]
Looking East from a short length of the D21, the galleried retaining structure, which is almost a viaduct, can be seen. [Google Streetview, March 2023]
The railway continues on a ‘berm’ built out from the East face of the Paillon valley and high above the D21, until it reaches the Ruisseau d’Euira.
This small extract from Google’s satellite imagery shows Le Paillon, the D21 and the railway in parallel. The railway bridge over the Ruisseau d’Euira is on the right of this image. [Google Maps, September 2025]
The Viaduc d’Euira crosses the valley of the Ruisseau d’Euira. The viaduct has one 30 m arch and two 5 m arches. [31]
The Tunnel de Santa Augusta (754 metres in length) runs under the Ste-Augusta Chapelle. [30]
The South portal of the Tunnel de Santa Augusta. As can be seen the tunnel runs straight between the two portals, allowing the light from the North portal to be seen from outside the South portal. This photograph was taken alongside the track crossing the Viaduc d’Erbossièra. [30]

Immediately to the South of Tunnel de Coletta the railway enters Peille Railway Station in Grave de Peille.
The approach to Grave Railway Station, seen from the cab of a Southbound service at the mouth of Tunnel de Coletta. [4]
Le Gare de Peille is situated on the East bank of the River Paillon on a pan artificial plateau which was created as part of the construction of the line from Nice to breil-sur-Roya. [26]
Peille Railway Station is located 6 km from the village of the same name, and serves the La Grave district, where the Vicat company operated a quarry and cement factory from 1924. A branch of the TNL tramway network reached this point from Pont-de-Peille. [1: p92]
At the South end of the Station site the line becomes single track once again adjacent to a house built originally for railway staff. [4]
South of Peille Railway Station the line passes this railway-built home, usually these houses were built for railway employees, either at a nearby station or working on track maintenance. [Google Streetview, April 2013]The line continues South towards Tunnel de Nogairet. [Google Streetview, April 2013]
Further South the line passes through Tunnel de Nogairet (32 metres in length). [Google Maps, September 2025]

Viaduc de Launa (100 metres in length – six 12-metre arches over the Galimbert stream) seen from the cab of the Nice-bound train running through the level-crossing. The viaduct was rebuilt during 1992 and 1993 as the first viaduct suffered settlement due to ground movement. [4]
Both this and the next image of the pedestrian crossing at Chemin de Laghet – a couple of hundred metres further along the line toward Nice – are of poor quality because of bright and low sunlight. [4]
Immediately to the West of Peillon-Sainte-Thècle Railway Station, the line crosses Pont de Brauschet (five 9 metre arches), seen here from the South on Avenue de la Gare. [Google Streetview, March 2023]
Pont du Brauschet sits just to the West of Peillon-Sainte-Thècle Railway Station and is marked on this map with a red arrow. It is 70 metres long and is a 5-arch viaduct.
Pont de Brauschet, seen from the cab of a train heading for Nice. [4]
The next structure along the line is Tunnel de Châteauvieux (219 metres in length). This in the East portal of the tunnel. [4]
Tunnel de Châteauvieux is the first of three tunnels which Nice-bound trains now pass through. It is marked by the red, blue and green dots on this image. Immediately to the West of this tunnel are the two side-by-side Viaducs des Mortes. [40]
This is the West portal of Tunnel de Châteauvieux, seen from alongside the line between the tunnel and Viaduc des Mortes. [40]
Just to the West of the Tunnel de Châteauvieux there are 2 viaducts next to each other (Viaducs des Mortes) of which only one is in service; the southern one which gives access to the Tuhet tunnel. The viaduct to the north (which has seven arches) leads to an unfinished tunnel. An accident occurred during the drilling of the original tunnel in 1925. The accident, which caused the death of 3 workers, resulted in the need to drill a new tunnel and, as a result, the construction of another viaduct in 1927 (with five 11 metre arches). The viaducts are named, Viaducs des Mortes, not because of the accident but because the viaducts bridge a footpath which was used to take deceased inhabitants of Borghéas to the cemetery of the neighbouring village of Drap.
The two viaducts mentioned above. [Google Maps, September 2025]

The featured image above is an early view of Thal Railway Station, possibly as early as 1903. [17]
The route of the Khushalgarh-Kohat-Thal Railway. The length from Khushalgarh to Kohat was initially built to the 2ft 6in narrow gauge in 1902 but converted to broad gauge (5ft 6in) at the same time as the River Indus was bridged, reopening in 1908. The line from Kohat to Thal was built to the narrow gauge (2ft 6in) and opened in stages from 1901 to 1903. [5]
Khushalgarh-Kohat-Thal Railway was worked by North Western Railway. [11] It was a military railway which ran close to the border with Afghanistan, linking the border town of Thal with the wider network at Khushalgarh.
By 1881, Khushalgarh had been connected by a short 7 mile (11 kilometre) broad gauge spur to Jand the North Western Railway main line. [1]
A line from Khushalghar to Kohat was first surveyed in April 1899. In 1901, it was decided to that to bridge the Indus would be too expensive. Instead, a ropeway was built over the river and a 2ft 6in (762mm) narrow gauge line was constructed from the right bank of the Indus facing Khushalgarh to Kohat, a distance of about 30 miles (48 kilometres) and opened in May 1902. [1]
The 62 mile (100 kilometre) line from Kohat to Thal ran from Kohat through the Kohat Pass and up the Miranzai Valley to Thal near the Afghan border. It opened in stages from Mar 1901 reaching Thal in Apr 1903. [2]
An intriguing haulage experiment is recorded by Simon Darvill. It took place in March 1902 on the trackbed of the line to Thal. A section of John Fowler [6] portable tramway was laid and a passenger carriage and two wagons were hauled by both a mule and a pair of bullocks. [3] The purpose and outcome of these experiments is not known. [5]
An on-line search of the India Office Records records held at the British Library relating to this line gives several entries, the most relevant being L/MIL/7/14848; “Collection 335/15 Railway construction: Loi Shilman, Kohat-Thal, Thal-Parachinar lines.”; 1908. [5]
The line closed sometime in the 1990s. Steam was still in use in 1989 as photographs here bear witness. [
Locomotives
An excellent discussion about various Bagnall supplied locomotives used on this line can be found in Allan C. Baker’s article in The Narrow Gauge No. 293 of March 2025. [12] Baker’s article is about the deployment of a series of Bagnall 2-4-2T locomotives built between 1901 and 1906 at the Castle Engine Works in Stafford (UK).

The Route of the Railway – Jand to Thal
Google Earth/Google Maps allows us to view the line from above, but no Streetview images are available in this part of Pakistan as of September 2025. Ground-level photography is only available at a number of specific locations.
Jand
As we have noted the first stretch of the line was built in 1881, linking Jand to Khushalgarh.
The location of Jand Railway Station. [Google Maps, September 2025]A closer view of the station. [Google Earth, September 2025]Khushalgarh Junction in Jand. The main line heads Southwest, the branch to Kohat heads West through Khushalgarh. [Google Earth, September 2025]
The line used to stop short of the River Indus. It did so from 1881 until the bridge opened in 1908. Khushalgarh could only be accessed by rope-worked boat across the Indus.
The Indus River Crossing
In 1903 an accident closed the ropeway over the Indus River and a boat bridge replaced it. Eventually the decision was made to construct the Khushal Garh Bridge [4] crossing the Indus river and, at the same time, to convert the line to Thal from narrow gauge to broad gauge. The length of the line to Kohat was converted by 1908 but conversion of the line to Thal was never completed.
The bridge is reported to have been constructed by a Mr Robertson and is the shortest bridge over Indus River. [7]
On this bridge the train track and vehicles road for vehicles are constructed together. The upper side is used for trains and lower one for general traffic. [8]
Khushalgarh on the West side of the River Indus. Originally passengers from Jand had to leave the broad-gauge train on the East side of the river and use the ferry to cross to Khushalgarh where onward travel was possible on the narrow-gauge line.
Wikipedia tells us that Kushalgarh is a village in the Kohat District of Khyber Pakhtunkhwa. [14] The modern railway station is some distance from the river.
Khushalgarh Railway Station is about 5 kilometres from the Indus along the line of the present railway and about 2 kilometres by road from the village of Khushalgarh. [Google Maps, September 2025]
The line West from Khushalgarh was initially 2ft 6in narrow-gauge. As noted above work commenced on its construction in 1901, opening as far as Kohat in 1902. The decision not to build a bridge over the river was shortsighted and by 1908 the bridge over the river had been built and the line West of the river was re-gauged, providing a broad-gauge service as far as Kohat.
Kohat Railway Station is now the terminus for passenger services. To the Southwest, there are a number of what appear to be industrial sidings. The line of the 2ft 6in gauge railway to Thal is apparently crossed by the runway of a Pakistan Air Force Base. Following the line of the old railway back from Hangu, it appears that the line runs round the South end of the Airbase runway. Possibly it was diverted when the runway was built.
It is possible to follow the line of the old railway to the terminus at Thal. The following images do this, file sizes have been kept to a minimum which means that image resolution is not great, but the whole route can be followed on Google Maps if a higher resolution is important.
The old railway left Kohat Railway Station at its Southwest end. The route of the railway crosses Bannu Road and turns South to run parallel to Bannu Road and the runway to the West. [Google Maps, September 2025]
Continuing South-southeast the route of the old line reaches the South end of the runway and curves through South to Southwest. [Google Maps, September 2025]
On this next extract from Google’s Satellite imagery the route of the old line can be seen curving round (South of the Green Flag marking Miagan Cricket Ground) towards the Northwest and crossing Kohat City Bypass Road. Google Maps, September 2025]
The route of the old line is visible to the point where it crosses Kohat City Bypass. To the West of the road the route of the old railway heads Northwest gradually separating from the line of the road. {Google Maps, September 2025]
The line of the old railway continues Northwest as the road turns to the North. The old railway formation is under a modern road at this point. [Google Maps, September 2025]
The old railway continued on the same bearing. The Kohat City Bypass crosses the route of the old line as shown here. [Google Maps, September 2025]

A significant change in direction of the road results in the route switching to the South of the road.
For a while the route of the old line runs a number of fields away from the Kohat-Hangu Road.
On both these extracts the route of the old line remains remote from the main road.
A modern access road follows the route of the old line.
The same applies for these next two extracts. [Google Maps, September 2025]
This section of the old line has not been annotated by red lines. It is clear that its route is now used as a highway. [Google Maps, September 2025]A further length of the old line follows a path remote from the modern road and much closer to the Jabi Toi River. The Kohat-Hangu Road takes up closer order with the route of the old railway towards to right of this image. [Google Maps, September 2025]
An enlarged view of the left side of the above image which shows the main road much closer to the line of the old railway. [Google Maps, September 2025]
The alignment of the old railway over this next length i more difficult to determine. It appears to curve around the North side of the swimming pool flagged at the top-right of the image and runs close to the Jawzara Springs. The lengths shown pink are surmised rather than certain. The route of the line is clearer once again towards the bottom of the image where it approaches a bridge over the Kohat Toi River, a tributary of the Jabi Toi River. [Google Maps, September 2025]
The redundant railway bridge over the Kohat Toi River remains standing. It is located just off the bottom-left of the satellite image above. [Google Maps, September 2025]
The bridge above is just off the right side of this satellite image. [Google Maps, September 2025]
The route of the old line continues on the South side of the main road.
The line continues Southwest avoiding the high ground which the road crosses and curves round to meet the Kohat-Hangu Road at the bottom-left of this extract, adjacent to the bus-stop shown bottom-left on the satellite image
The route of the old line runs on The South side of the road before curving West-Northwest and crossing he road.
A relatively tight curve takes the route of the old line back across the modern road. At the centre of this image, Hangu Bypass now follows the route of the old railway.[Google Maps, September 2025]
Hangu Bypass continues to follow the lie of the old railway on the Southeast side of the city and does so until the Bypass meets the Thall-Hangu Road. [Google Maps, September 2025]
A closer view of the road junction shows the route of the old railway running immediately alongside the Thall-Hangu Road. [Google Maps, September 2025]
The route of the old line continues running parallel to the main road. [Google Maps, September 2025]
The two separate somewhat as the route of the old line continues South-southwest and then turns to the Southwest. [Google Maps, September 2025]
The route of the old line continues Southwest. [Google Maps, September 2025]
Further Southwest the route of the old line returns to the shoulder of the modern road.
It runs immediately alongside the road for a short distance, before turning away to the South.
The change od direction can be seen at the bottom-left of the last image and appears more clearly on this extract. Its route is followed by a minor road.
The old line continued Southwest before turning to the West. [Google Maps, September 2025]The old line ran West before turning to the Northwest. [Google Maps, September 2025]Heading Northwest, the line eventually crosses the Thall-Hangu Road. [Google Maps, September 2025]It then turned West to run along the North side of the Thall-Hangu Road, before starting to drift away to the North of the road. [Google Maps, September 2025]The line headed Northwest and then West-northwest. [Google Maps, September 2025]The old railway crossed the river bed at the bottom left of this extract from Google’s satellite imagery, turning first to the Northwest and then generally to the West. [Google Maps, September 2025]
Bottom-right on the image above the old railway bridged a dry river bed on a two-span girder bridge which is still standing in the 21st century. [Google Maps, September 2025]
This next length of the line ran South-southwest before curving a little to the Southwest, and then, as can be seen on the next extract from Google’s satellite imagery, towards the West-southwest to run parallel to the Thall-Hangu Road. [Google Maps, September 2025]
The route of the old line runs on the North side of the Thall-Hangu Road. [Google Maps, September 2025]The route of the old line drifts away from the Thall-Hangu Road. [Google Maps, September 2025]Topography dictated that the line took a circuitous route first turning to the Northeast before swinging round to the Southwest. [Google Maps, September 2025]After a length running Southwest the line turned West. [Google Maps, September 2025]It continued in a westerly direction.

The formation is under a road for the majority of its length. [Google Maps, September 2025]The route of the old line continues through Darsamend turning to the Southwest. A road follows the formation over the majority of this length. [Google Maps, September 2025]Still in Darsamend, the approximate route of the old railway crosses the Thall-Hangu Road at a shallow angle. [Google Maps, September 2025]The railway bridge still stands (close to the centre of this image with the old railway running Northeast to Southwest and now used as a road. [Google Maps, September 2025]The old railway route can be seen to the South of the Thall-Hangu Road running from the top-right corner of this image, crossing the Thall-Hangu Road close to the bottom-left of the image and running on the North shoulder of the road to the bottom-left corner of the image. [Google Maps, September 2025]The red dashes mark the line of the railway through Mammu and over a dry river bed. The bridge no longer exists and the route of the line through the village has been converted into a road. [Google Maps, September 2025]The route of the old railway runs from the cutting at the top-right of this satellite image,m West along what is now a road before turning South towards the Thall-Hangu Road. It leaves this image just to the North of the Thall-Hangu Road. [Google Maps, September 2025]There is an overlap between the last satellite image and this image the line of the old railway can be followed, first along the grey road on the North side of the Thall-Hangu Road and then as a paler line running through the landscape towards the bottom-left corner of this image.

[Google Maps, September 2025]Heading West from the road at the left of the image above the line then turned to the Southwest and its route again appears relatively clearly running from the top-right to the road at the bottom-left of this satellite image. [Google Maps, September 2025]The route of the old railway is defined by the narrow paler line which runs from the road at the top-right of this satellite image (which is the same as that in the bottom-left of the image above) in a South-southwest direction before curving sinuously toward the Thall-Hangua Road at the bottom left of the image and running South for a short distance to the East of the road. [Google Streetview, September 2025]The exact point at which the railway crossed the line of the road is not obvious, but we can see the line of the railway crossing the land between two arms of the Thall-Hangu Road. It appears as a shallow cutting curving gently towards the Southwest, to the North of a more significant defile. [Google Maps, September 2025]The approach to Thal Railway Station no longer is easy to identify. The last length of the line which can be ascertained easily is this apparently deep cutting.

The North Western Railway (NWR) was a major railway system in British India that served the North-West Frontier region. After the 1947 partition, it was split, with the majority of its lines becoming the foundation for Pakistan Railways and a smaller portion forming the Eastern Punjab Railway in India. The NWR was headquartered in Lahore and extended from Karachi to Delhi and into the frontier regions, a crucial infrastructure for both civilian transport and British strategic planning. See: https://en.m.wikipedia.org/wiki/North_Western_State_Railway, accessed on 20th September 2025.

The Coleford Branch between Monmouth and Coleford replaced an earlier tramroad. The Monmouth Tramroad, linked Monmouth with Coleford and opened in 1810. It was the first rail transport in the immediate area.
Wikipedia tells us that the “Monmouth Railway Act was a Parliamentary act from 1810 (50 Geo. 3. c. cxxiii) that authorized the construction of a 3 ft 6 in gauge plateway, a type of early tramroad, from mines east of Coleford to May Hill in Monmouth, running through Redbrook. The purpose was to create a toll road for carriers to transport coal and iron ore, but it would not be operated by the company itself. The line opened in stages between 1812 and 1817.” [4]
For just under half a century this was the only ‘railway’ serving Monmouth. This was true for even longer in respect of Coleford.
It is of interest that this line was originally planned to be at the core of a significant network. It had a long tunnel near Newland and is thought to have been the first railway to include a paying passenger service within its Act. [1]
The original tramway bridge (pictured towards the end of this short article) was a low timber girder on stone abutments crossing a minor road serving a couple of farmsteads. This created a large loop up this side valley, which initial plans for the railway involved amputating and replacing with a gently curving viaduct.
Viaducts are expensive, however, and taking a straight course means going a shorter distance and consequently trains would have to climb more steeply. So the viaduct was dropped from the plans and replaced by a huge embankment which made a smaller loop up the side valley. Through this embankment passed the new bridge for the minor road. Although it is a rather large structure (particularly by single arch standards), the top of the arch is still well below the top of the embankment, which carried a minor single track railway. It now carries an overgrown trackbed which is about the same width as the road below. The railway was built to last and, 92 years after the last train to Monmouth from Coleford, the Dog Kennel Bridge remains in excellent condition.
Dog Kennel Bridge, seen from the Northwest on Whitecliff. The featured image at the head of this article is a photograph taken by me on 3rd September 2025. It shows the same structure, seen from the Southeast on the same minor road. The featured image is repeated below. [Google Streetview, March 2025]The featured image for this short article is a photograph of Dog Kennel Bridge as seen from the Southeast. The bridge is unusual, being more like one span of a tall viaduct than a single-span arches bridge. [My photograph, 3rd September 2025]The red dot marks the location of Dog Kennel Bridge. The line of the branch can be made out as two parallel lines of trees which pass to the West of the ‘flag’ marking the position of Whitecliff Ironworks. [Google Maps, September 2025]The extract from the 25″ Ordnance Survey of 1900, published in 1902, shows the location of Dog Kennel Bridge in relation to the small town of Coleford. The bridge is in the extreme bottom-left of the map extract. Coleford’s two adjacent stations feature in the top-right of the map extract. [2]The red dot marks the location of Dog Kennel Bridge. [Google Maps, September 2025]The 25″ Ordnance Survey of 1900, published in 1902, shows the GWR single-track line crossing Dog Kennel Bridge. The earthworks for the older Monmouth Railway are visible running across the map extract on the South side of the GWR line above Whitecliff Villa, passing under the GWR line to head further up the valley before curving tightly over the road. [3]
Dog Kennel Bridge carried the Coleford Railway, which ran from Wyesham Junction, near Monmouth, to Coleford, over a minor road between Whitecliff and High Meadow Farm. Construction of the line began in 1880, the contractors being Reed Bros & Co. of London, and it was opened on 1st September 1883. In common with other underbridges on the line, Dog Kennel Bridge is predominantly of stone, but the arch is made of brick. It has massive stone abutments and wing walls. The smaller stone bridge abutments of the Monmouth Railway, which the Coleford Railway replaced, are still visible about 100 metres up the lane (SO 56321007) where the old tramroad crossed the valley on a much sharper curve. [5]
The abutments of the tramroad bridge remain on either side of Whitecliff. This is how they appear from the Southeast.

The GWR’s Coleford Branch closed by 1st January 1917, most of the track soon being lifted for the war effort. [5]

In the first five articles about the line from Cuneo to the sea we covered the length of the line from Cuneo to Breil-sur-Roya and then to Ventimiglia. These articles can be found here, [9] here [10] here, [11] here, [12] and here [13]
I want to acknowledge that a series of stills from a video of the train journey from Breil-sur-Roya to Nice have been used in this article. The video can be seen here. [4]
This article begins the journey from Breil-sur-Roya to Nice.
South of Breil-sur-Roya a junction allows direct access to Ventimiglia and to Nice. The map below shows the two routes as they existed prior to the alteration of the border between France and Italy after the Second World War.
The lines Nice to Tende and Ventimiglia to Tende in the period from 1928 to the Second World War, before the annexation, in 1947, of St-Dalmas de Tende and Piene to France. [40]
The project was finally agreed by the PLM on 7th January 1907 but various portions of the work would be delayed by disputes relating to the transfer of land. “Acquisitions began in the suburbs of Nice in May 1907, at Saint-Roch … and Roccabiliera, where the PLM had decided to build a vast facility with a goods station, marshalling yard and engine depot to relieve congestion at Nice central station, whose rights of way, enclosed in the urban fabric, could no longer expand. This program for the redesign of Nice’s railway facilities also provided for a 3,610 m connection between the new Saint-Roch station, Riquier station and the port. In the hinterland, events also began to take shape and in December 1908, a section of engineers set up in Fontan and undertook the first work along the Roya the following January.” [1: p90]
Banaudo et al continue: “In 1909, Chief Engineer Paul Séjourné (1851-1939), then fifty-eight years old and already renowned for his original designs for civil engineering structures, took over the direction of the construction department. The line from Nice to the Italian border would give him the opportunity to exercise his talent in the design of structures that were as daring as they were harmoniously integrated into the landscape.” [1: p90]
In this series of articles, we have already seen Séjourné‘s Scarassoui Viaduct spanning La Roya to the North of Breil-sur-Roya.
The line from Breil-sur-Roya to l’Escarene. [
This article follows the line South from Breil-sur-Roya to l’Escarene in two parts. The first from Breil to Sospel and the second from Sospel to l’Escarene.
1. The Line South from Breil-sur Royato Sospel
Banaudo et al tell us that, “In December 1912, tranches 8 and 9 were awarded in turn for a length of 10,500 m from Sospel to Breil to the François Mercier company, of Moulins-sur-Allier. The work included three tunnels with a combined length of 5,307 m, including the Mont Grazian and Caranca structures established at double-track gauge and equipped with defensive devices, as well as seven bridges and viaducts representing twenty-five masonry arches and two metal spans. Among them, the exceptional structure of the Bévéra viaduct. There were also three culverts and three level crossings in this section.” [1: p102-103]
Banaudo et al take up a significant part of Volume 1 of the story of the line with an album of photographs of the construction work on the French side of the border. [2: p152-331] A superb record of the work undertaken.
On the Sospel-Breil section of the line the contract works were gradually completed. By the end of 1921, the Bancao and Caranca tunnels were completed. The Mont Grazian tunnel was finished in 1923. The Bévéra viaduct’s abutments and masonry arch were ready by then and only awaited the delivery of the metalwork of the decking. [1: p141]
The length of the lien from Breil-sur-Roya (top-right) to l’Escarene (bottom-left). [8]
This drawing/map shows the two routes heading South from Breil-sur-Roya. [40]
As with the line immediately to the North of Breil-sur-Roya, the works to the South and Southwest were constructed by the French. Both of the lines heading South from Breil-sur-Roya entered tunnels just a short distance South of Breil.
The first length of the line South of Breil-sur-Roya is common with the line to Ventimiglia. The two lines separate at the Lavina bridge.

The photograph was taken from the hillside to the Northwest of the station site and faces Southeast, (c) Public Domain. [30]After the war, the line to Nice was reopened in 1947, but the station, reduced to the simple terminus of a secondary section, was greatly simplified, removing almost all the sidings (the long straight lines of which can still be made out). In the background, the line to Fontan still features the electrification poles (removed from the rest of the station), but it was naturally abandoned and remained there until its reconstruction in the 1970s. In the 21st century, platform 2, which had been removed at the time, has been restored, the buildings on the second platform have been scaled down, and the third platform has been eliminated.

The line to the West is the line we are now following from Breil-sur-Roya to Nice which is at a much higher level and its viaduct is a multi-span structure. [15]

The Mont Grazian Tunnel was built wide enough to accommodate double-track to allow for possible future traffic growth. “It was lined with defensive measures at both ends, a precaution imposed by the major strategic importance of this structure, which connects the Roya and Bévéra valleys.” [1: p94] Details of the defensive measures can be found here.

A very short distance beyond the end of Viaduc de Bassera, the line crosses the River Bevera on another viaduct – Viaduc Cai. [4]
This extract from OpenStreetMap illustrates the proximity of the two viaducts and Mont Grazian Tunnel. [22]
Due to its proximity to the Italian border, this unused tunnel (marked with a red arrow) was built for strategic reasons as part of the Maginot Plan for the defense of the SFAM (Fortified Sector of the Alpes Maritimes). [28]
It was intended to provide an emergency route in the event that the large neighboring Caï viaduct needed to be destroyed, and to store the metal spans of a replacement viaduct. [28]
Halfway along its length, on the left wall, it has an annex gallery (tunnel window – marked by the yellow arrow) which opens onto the western abutment of the Caï viaduct. More information can be found here. [28]
The Bevera River flows West to East (its confluence with La Roya (Roia) is adjacent to the village of Bevera which sits on the North bank of the Bevera River). Once across the Bevera River on the Cai Viaduct, the line heads up a gradient of 17 mm/m to Sospel Railway Station.
The route of the line between Breil-sur-Roya and Sospel was determined by the military. The military authorities dictated that the line should be routed to ensure that it could “be easily intercepted by the artillery of The Barbonnet fort, above Sospel, in the event of an infiltration attempt from the Roya valley.” [1: p92 & 94]
The Cai or Bevera Viaduct “crosses the river at a very acute angle. [This] inspired an original arrangement by Paul Séjourné: the deck, formed of two metal spans of 45.30 m, framed by four masonry arches of 8 m, rests 30 m above the river on a perpendicular arch of 25 m opening and egg-like in shape, resting transversely on the walls of the gorge.” [1: p94]
The line follows the valley side to the South of the Bevera rising, as we have already noted at a gradient of 17 mm/m. It crosses a minor road by means of a level crossing (Route de Suez).
The level crossing at Route de Suez, seen from above. [Google Maps, August 2025]

The final approach to Sospel railway Station from the East. [4]
Sospel Railway Station was to be a station “with substantial facilities which would allow the reception of military convoys in the event of conflict with neighboring Italy.” [1: p92] Arriving on Sospel, trains from Breil-sur-Roya pass through a large flat open area which was designed to accommodate the needs of the military.
The town was, in the middle of the 19th century, the second city of the County of Nice. “The location of Sospel … in … a basin where the Bévéra Valley widens, is very unique. From wherever one arrives from France, one must cross a pass: the Braus pass coming from Nice, the Castillon pass towards Menton, the Brouis pass towards Breil and La Roya, and the Turini pass towards La Bollène and La Vésubie. Towards Italy, the Vescavo Pass road connects Piena and Olivetta, while downstream, the Bévéra flows in impassable gorges where one could only venture on foot.” [1: p101-102]
The year 1912 was quite momentous in the history of Sospel not only was construction work getting underway but on 15th April 1912 the Compagnie des Tramways de Nice et du Littoral (TNL) opened its Menton-Sospel tramway. More about the tramway can be found here, [36] here [37] and here. [38]
Closer to the centre of Sospel, this is the terminus of the Menton-Sospel Tramway. [46]
Banaudo et al comment that “The Gianotti company immediately took advantage of this opportunity to transport the tools and equipment from Nice that would be used for the construction of the Braus tunnel. … In the initial stages of the construction, the Gianotti brothers used a network of portable 0.60 m gauge railways, on which Decauville dump trucks pulled by horses ran. Later, one-metre gauge tracks were laid, on which steam locomotives pulled larger capacity trains, consisting of Koppel wagons with a load of 6 m³ or wooden-bodied wagons with a capacity of 3 m³. Several locomotives from the contractor were brought to site via the tramway, coupled to a ‘mortrice electrique’ (an electric tram engine) as a safety measure on the steeply graded tramway.” [1: p102]
“In the early months of 1913, the Mercier company got to work and obtained permission from the TNL company to open a special branch line at each end of the Menton-Sospel tramway line. The construction site’s supplies then provided the tramway with more than half of its freight traffic. In July 1913, two to three round trips ran daily, and in October, Mercier received 745 tons of materials in Sospel. In May 1914, the Gianotti brothers opened their own branch line in the Careï Valley in Menton, but soon, the saturation of the small freight yard and insufficient equipment forced the TNL to limit shipments to five wagons per day.” [1: p103]
2. Sospel to l’Escarene
The journey from Sospel to l’Escarene takes the line through and under the mountains of the Col de Braus.
The line climbs through a series of embankments and cuttings on a gradient of 9.5 mm/m and enters the Tunnel de Braus.It continues to climb within the tunnel to a high point of 420 metres above sea level. Within the tunnel the gradient then changes to a 2 mm/m downward grade towards l’Escarene. The tunnel was double-track both to aid ventilation and to allow for possible expansion of services if demand required it. At the insistence of the military defensive fortifications surrounded the two tunnel mouths. [1: p92]
Of the 12 tranches of contract work on the French side of the international border, two tranches covered the 9.7 km length between Sospel and l’Escarene – lots 6 and 7. The work was awarded in December 1911 and April 1912 to Jean and Antonin Gianotti. Banaudo et al tell us that the work included over 6.4 km of tunnel. “As well as a few secondary structures: three culverts, four level crossings, two underpasses and six overpasses, most of which were built using the new reinforced concrete technique.” [1: p101]
After waiting for a Breil-sur-Roya-bound service to clear the line ahead, we set off in a Westerly direction from the station at Sospel.

The same tunnel mouth in better light. [31]
The full length of Tunnel de Braus (5.94 km long), as it appears on OpenStreetMap. [30]The full length of Tunnel de Braus as it is recorded in the French Inventory of Tunnels. The yellow dot marks the approximate location of a significant water flow intersected by the construction work which required significant remedial works before the construction of the tunnel could proceed. More information and drawings can be found here. [31]
As we have already noted, both the tunnel portals were fortified at the insistence of the military. … Completing the tunnels also required significant additional work to deal with a very high level of water ingress during construction.
The Southwest portal of Tunnel de Braus is flanked to the Southeast by a very high retaining wall and to the Northwest by a water channel created for the Ruisseau de Redebraus. [31]
The Tunnel de Braus was built to accommodate a double-track line to allow for possible future growth in traffic.

These two images show the Station site from above. The red ring highlights the location of the station turntable which, in the 21st century, is the location of the town’s fire station. [35]]
L’Escarene sits at the top of a long climb from Nice. We will follow the line through to Nice in the next two articles in this series. (The next article can be found here. [5]) Like Sospel, l’Escarene Railway Station had substantial facilities on a wide open plateau designed to allow the reception of military convoys in the event of conflict with neighboring Italy.

This drawing/map shows the two routes heading South from Breil-sur-Roya. [40]
As with the line immediately to the North of Breil-sur-Roya, the works to the South were constructed by the French. Both of the lines heading South from Breil-sur-Roya entered tunnels just a short distance South of Breil.

[30]After the war, the line to Nice was reopened in 1947, but the station, reduced to the simple terminus of a secondary section, was greatly simplified, removing almost all the sidings (the long straight lines of which can still be made out). In the background, the line to Fontan still features the electrification poles (removed from the rest of the station), but it was naturally abandoned and remained there until its reconstruction in the 1970s. In the 21st century, platform 2, which had been removed at the time, has been restored, the buildings on the second platform have been scaled down, and the third platform has been eliminated.

Bancao Viaduct on the line from Breil-sur-Roya to Ventimiglia is close to the D6204 on this extract from OpenStreetMap. The line to the West is the line from Breil-sur-Roya to Nice which is at a much higher level. [14]
Looking West from the D6204/E74, a small culvert close to the road is dwarfed by the bridge carrying the line to Ventimiglia which in turn is dwarfed by the viaduct carrying the line to Nice. [Google Streetview, April 2008]

This smaller image, looks South along the D6204/E74. The railway can be seen adjacent to, but above the road. To the West side of the line, large retaining walls create space for the line on the steeply graded valley side. {Google Streetview, July 2014]
A little further South the Hydroelectric Plant is now visible. [Google Streetview, July 2014]

Now just beyond the Power Station , again looking South with a high retaining wall above the railway which sits a few metres above road level on the right. Three arcades carrying the line are followed by the three stone arches of the Riou Viaduct. [Google Streetview, July 2014]
Construction work on the Italian length of the line in the lower Roya (Roia) Valley began in Ventimiglia. Banaudo et al have chosen to follow the line from South to North to reflect the way this section of the line was constructed. We continue to follow the line from North to South.
The length of the line from the border at Piena (Piene) to Airole was completed before the first world war but traffic along this part of the line had to wait for completion of the length of the line in French territory. The Italian authorities decided that services would commence only between Ventimiglia and Airole. That length is covered later in this article.
The international border at the time of construction was just to the North of Piena (Piene). That border line remained the same through the interwar years. Services North from Airole via Piena to Breil-sur-Roya had to wait until 1928 and the opening of the full line.
The Riou Viaduct (three 6.25m masonry arches) was the location of the international boundary. Banaudo et all tell us that the point that the line crossed the boundary is marked by the letters I and F engraved in a stone on the deck of the structure. [1: p125]
The Riou Viaduct straddled the centuries old border between Genoa and Savoy which became the border between Italy and France. This view looking South along the D6204/E74 shows the arcade retaining wall (3 bays) followed by the three-arch viaduct. [Google Streetview, July 2014]This view looks North along the D6204/E74 towards Breil-sur-Roya. The three arches of the Riou Viaduct are on the left of the image. [Google Streetview, July 2014]
Immediately to the South of the Riou Viaduct, Piene (Piena) Station was built as a frontier station below the village of Piena-Alta which, Banaudo et al tell us, was for centuries the outpost of the Genoese republic and the border with the States of Savoy. [1: p125-126]
Close to the road border post at Piena-Bassa, the “Italian administration decided to establish a station intended for police and customs control operations. There were three platform faces, a two-story passenger building and a customs clearance hall of the same size for goods, comprising a warehouse, offices and two apartments on the upper floors. The site was hemmed in by the tunnel to the South, the French border to the North, the mountainside to the West, and the Roya River to the East, necessitating the construction of the station, cantilevered over a masonry gallery supported by seven arches, above the SS 20 roadway.” [1: p126]

Writing about the length of the line between Ventimiglia and the border at Piena (Piene), Banaudo et al say: “In the lower Roya Valley, the seven tranches of the Ventimiglia – southern border section were successively awarded in 1908, 1910, 1911, 1912, and 1913. Despite the lower altitude, the route was as difficult as on the purely Alpine section of the line, with steep gorges and terrain that offered highly varied resistance to earthworks: unstable marly limestone, very hard black limestone, clayey marl, schist, sandstone, etc. Of the 17,260 m route, nearly half way to be in tunnels, with nineteen structures totaling 8,259 m, fifteen bridges and viaducts representing sixty-four masonry arches, as well as various secondary structures for crossing waterways and rural roads.” [1: p118]
Piene Railway Station to Airole Railway Station. [22]
South of Piene (Piena) a series of structures carry the line over or through the obstacles in its path:
• the Fromentino Tunnel, 645 m long; • a viaduct with three 10 m arches; • the Arme Tunnel, 333 m long; • a viaduct with four 10 m arches; • the Agrie Tunnel, 820 m long; • the Fanghetto tunnel, 419 m long, extended by a gallery (the post-WW2 border was established at the North end of this tunnel); • the Sardinesca Tunnel, 820 m long; • a single span arch bridge over the Tron valley.
These are all illustrated below.

A view, looking South from the SS20, of the northern mouth of San Michele Tunnel with an Italian Locomotive heading into the tunnel (I may well need correcting on this) is shown in more detail below… It appears to be a Belgian locomotive (SNCB) No. 7336 with the name, ‘Mexico’. [Google Streetview, August 2021]
This picture it taken just a short distance to the South of the image above. It shows a side-on view of the same locomotive. I would not expect to see this locomotive at this location! [Google Streetview, August 2021]
This is SNCB 7304 – the image is provided by Wikipedia. The family resemblance with 7336 is manifest. The Class 73 locomotives formed the backbone of the SNCB/NMBS shunting locomotive fleet. [20]
Class 73 locomotives were built in three batches: 7301-7335 during 1965–1967, 7336-7375 during 1973-1974 and finally 7373–7395 in 1976–1977. [20]
This is the view North through the station site as seen from the cab of a Northbound service at the North postal of the San Michele Tunnel. [35]
Looking out from the Southeast portal of San Michele Tunnel, the line ahead crosses Roya IV Bridge which is 126 metres in length and then enters Mantici Tunnel which is 604 metres long. [55]
One hundred metres further South and turning through 180°, this is the view across Roya IV Bridge towards the San Michele Tunnel. Note that the road tunnel is just above the railway tunnel, although on a different line. [35]
The view from the road above the Southeast portal of San Michele Tunnel. The mouth of Mantigi Tunnel (604 metres long) can be seen at the end of the railway viaduct. [Google Streetview, August 2021]
A very short distance along the road a somewhat better view of the viaduct. [Google Streetview, August 2021] More views of the viaduct can be seen here, [17] here, [18] and here. [19]
Roya IV Bridge was also known as the San-Michele Viaduct. It was made up of five 15 metre arches. [1: p125]
The Mantigi tunnel has a short section where it is very close the the surface of the ground above, Banaudo et al, tell us that this allowed the provision of a vertical ventilation shaft. [1: p125]
Trains travelling South to Ventimiglia crossed the viaduct and ran on through Mantigi Tunnel. Airole Railway Station was originally on a large plateau beyond the Southeast portal of Mantigi Tunnel.
The original location of Airole Railway Station. The substantial passenger building remains. The walls of one other building can be seen to the Southeast of the passenger facilities. [Google Maps, August 2025]
Banaudo et al tell that “Airole station was located in an olive grove to the North of the village, in the only place where the shallower slope of the left bank of the Roya allowed the construction of a retaining wall to support all the railway infrastructure: the passenger building, three platform tracks and two freight tracks with a goods shed and high platform, as well as a water column for the locomotives.” [1: p121]
The station was built in 1914 and remained operational until, sadly, the station site was abandoned in the 1970s when it was replaced by a single platform halt in the centre of Airole. [25]
At the southern end of Mantigi Tunnel, trains enter a passing loop (Airole Loop), which is all that is left of the original railway station, before entering another tunnel! [55]
Looking back towards Breil-sur-Roya from within the passing loop. Immediately to the North of the loop, Northbound trains plunge into the Mantigi Tunnel. [35]
Looking North from the cab of a Northbound train approaching the old railway station building. It is evident from both these pictures that there were originally sidings at this location – confirmation that the station facilities at Airole were once quite significant. [35]
At the end of the passing loop trains enter Madonna Tunnel (249 metres long). [55]
Looking back towards Breil-sur-Roya from the portal of Madonna Tunnel. The passing loop is still provided at this location as there is no room at the present Airole Railway Station for more than a single track. [35]
Leaving Madonna Tunnel trains immediately pass under a local road bridge which appears as not much more than a silhouette as eyes get used to the light on leaving the tunnel. [55]

Looking back from the Delle Bocche tunnel mouth across the Roia No. 1 bridge. [35]
Banaudo et al tell us that the length of the Roia (Roya) Valley that we have just traversed is known as the ‘Bocche’, “the wild gorges of the Roya which for a long time represented an abstacle to communications between the Ligurian lands of the Republic of Genova and the Piedmontese domain of the Kingdom of Sardinia. It was only in 1893that the … road from Ventimiglia to Breil was completed … after lengthy construction work hampered by the difficult terrain and the reluctance of the military authorities. The railway tamed this gorge through an uninterrupted succession of tunnels and viaducts.” [1: p121, 125]
Delle Bocche Tunnel (927 metres long) ends at the top of this OpenStreetMap extract. There is a short bridge which carries a length of the line before Southbound trains enter d’Allaveri Tunnel which, although it appears as one tunnel on the map extract is actually two tunnels with a very short open length in between. The Aqueduct illustrated on the map passes under the railway in that opening in pipes, (Pont sur les conduites forcées de la centrale hydroélectrique de Bevera). The first length of the tunnel is named d’Allaveri Tunnel (69 metres long), the second length is known as Serro Soprano Tunnel (245 metres long).
Once beyond these tunnels, Southbound trains have a clear run down to Bevera Railway Station. [24]

The class is based upon the standard Vossloh locomotives design, and they are a higher powered development of the Vossloh G800 BB which were produced mainly for the Austrian Federal Railways, with a 1.1 MW (1,500 hp) MTU engine replacing the 0.8 MW (1,100 hp) Caterpillar engine in the G800; as a result the front engine compartment is enlarged, whilst other features: bogie frame and overall dimensions remain the same.

Banaudo et al write that “the single track of the Col de Tende line runs alongside the Nice double track for a few hundred metres. [Initially] they crossed the Roya River together on a six-span metal viaduct, which was soon replaced by a new structure with eight 17-metre stone arches. Immediately beyond the bridge, the two routes separate and the Cuneo route climbs up the right bank of the river, at a gradient of 13 mm/m, the valley is still relatively wide. A bundle of three service tracks called Scalo Roia is located to the left of the main track. The Isnardi tunnel (168 m long) and Maneira tunnel (171 m long) precede a four-arch viaduct (with 6-metre arches).” [1: p119] This description assumes that the line is followed West out of Ventimiglia Railway Station.
Banaudo et al comment thatwhile construction was just beginning between“Breil and the southern border, the work begun in 1908 by the Italian companies from the coast was nearing completion. While awaiting the connection to France, the FS decided to operate the Ventimiglia-Airole section (11.970 km), which entered service on 16th May 1914. The service was provided by three round trips, including two local passenger trains and one mixed train, which covered the entire route in about thirty minutes uphill and twenty-five minutes downhill. Traction was provided by three-axle 030 locomotives with separate tenders, Group 320 (formerly the 3600 of the Rete Mediterranea), based to the newly created Savona depot.” [1: p142]
In France, WWI caused the cessation of all work on the line and in the aftermath of the conflict, “the resumption of construction proved very difficult. The PLM’s construction department received only meager allocations from the state, with priority funding being allocated to the recovery of the disaster-stricken regions of the northeast.” [1: p138]
On site, the years of inactivity had allowed serious deterioration, particularly of the tunnels on the unopened line. Following a three-day inspection tour of the entire line, the French decided to begin work once again.
The contractors made a significant investment in manpower and materials at the beginning of 1920 but discovered that rather than dealing with the PLM, the works would be directly funded by the government. The government determined that the budget for the work on French soil would be reduced from 104 to 75 million Francs and indicated that the maximum spend in 1920 would be 17 million Francs. This inevitably led to redundancies and to slower progress of the works. [1: p140]
When the authorities indicated in June 1920, that “only 700,000 Francs of credit remained to complete the year, … the elected officials of the Alpes-Maritimes immediately rushed to Paris to meet with representatives of the Ministry and the PLM management. Following discussions, a new budget was allocated by the State for railway construction. The PLM had a budget of 41 million Francs, 25 of which were allocated to the Nice-Cuneo line. Work could [continue], but the engineers and contractors in charge of it would have to take into account the irregular arrival of funds until the end when organizing their work.” [1: p140]
Work on the Nice to Breil-sur-Roya line and the remaining length of the line between Ventimiglia and Breil ran in parallel. The increased budget meant competition to attract staff was strong and people had to be hired from Italy, Spain, Portugal and Morocco. Stonemasons were in particularly short supply. We will probably see more about what this meant for the work when we follow the line from Breil-sur-Roya to Nice.
Banaudo et al note that in the early 1920s the line was opened between Ventimiglia and Airole for passengers and was used also to supply the French construction site on the length of the line between Breil-sur-Roya and Piena (Piene).
“From Breil to the southern border, the [railbed/formation]was passable by 1921 and the final track was immediately laid, while the FS did the same between Airole and Piena on the section removed during the war. On30thJanuary 1922, the Italian and French rails were finally connected on the Riou bridge, and the Borie company obtained from then on the authorization to directly route its materials from Nice to Breil by rail.” [1: p142]
Once the line opened fully between Ventimiglia and Cuneo, the line “retained the Ventimiglia-Airole service created before the war, while on the Cuneo San-Dalmazzo-di-Tenda line, the timetable included three daily three-class buses and a seasonal train running on public holidays from July to September. The 58 km journey took 2 hours 30 minutes in the north-south direction and 2 hours 10 to 15 in the opposite direction. This service included one less return journey than in 1915, because a fast Cuneo Nice bus connection was introduced in 1921 following an agreement between the FS and the Compagnia Generale dei Tramways Piemontesi (CGTP), to avoid the inconvenience of transhipment while waiting for the railway to be fully operational.” [1: p143-146]
In December 1923 it was agreed that on the length of line between the two borders, “all trains … would be hauled by the FS, including maintenance trains; in the event that they had to be exceptionally handled by a French locomotive, the latter would be accompanied by a pilot from the FS. The San-Dalmazzo Piena section would be equipped with Morse-type telegraph devices. The protection signals for Breil station on the Fontan-Saorge and Piène sides would be Italian, but the departure signals for all directions would be the PLM-type. The organization of customs controls between San-Dalmazzo, Fontan-Saorge, Breil and Piena was also [agreed].” [1: p146]
Banaudo et al provide a significant series of photographs of the construction work on the lines between Cuneo, Nice and Ventimiglia which takes up a large proportion of Volume 1 of Les Trains du Col de Tende. The photographs and drawings are predominantly from the French lengths of the line. [1: p152-311] It is a very significant collection of images which stand as a superb tribute to the amazing work of the various contractors employed on the line.
Opening of the line from Cuneo to Ventimiglia to passenger traffic had to wait for the completion of all of the French construction work. “Finally in October 1928 the lines were all completed – the celebrations must have been fantastic events. At last the small towns and villages along the route had access to jobs, schools and universities, cultural activities, hospitals … everything the cities had to offer.” [39]
The next article in this short series will look a the line heading out of Breil-sur-Roya towards Nice. It can be found here. [5]

1. The Line South from St. Dalmas de Tende as far as the French/Italian Border …
St. Dalmas de Tende (San-Dalmazzo-di-Tenda in Italian) was “the last station on Italian territory, before the northern border. This is where the French Forces would install a large-scale border station that will handle customs clearance operations in addition to the French facilities at Breil. In the first phase, a temporary passenger building and a small freight shed were built on the vast embankment created from the spoil from the tunnels upstream of the confluence of the Roya and Biogna rivers. The original layout includes four through tracks, one of which is at the platform, five sidings, three storage tracks, a temporary engine shed, a 9.50 m turntable, and a hydraulic power supply for the locomotives.” [1: p127]
It is here, at St. Dalmas de Tende, that we start this fourth part of our journey from Cuneo to the coast. Before we do set off southwards we note that the Tende to La Brigue “tranche of the work on the line was awarded to the Tuscan contractor Enrico Lévy, and the Briga to St. Dalmas de Tende tranche was executed by the Rosassa company of Alessandria. Work began in 1912 and progressed more quickly than upstream of Tende, thanks to the opening of the construction sites during public holidays and the use of new compressed air drills.” [1: p129]
The line from Tende (Tenda) to San-Dalmazzo-di-Tenda (St. Dalmas de Tende) was opened on 1st June 1915. The three of the four daily services were connected to the Southern arm of the line which by this time had reached Airole, by a coach shuttle. [1: p131]
A temporary station was provided as a terminus of the line from Cuneo. It was sited to the Northeast of the present large station building which was not built until 1928.

From San-Dalmazzo (St. Dalmas), the railway forms two horseshoe loops underground, crossing the Roya three times over a distance of just over a kilometre as the crow flies.
The Biogna Tunnel is the first of these horseshoe tunnels, it is 1154 metres long. We have already seen the approaches to the tunnel from St. Dalmas de Tende Railway Station. The tunnel’s horseshoe shape can be seen on the OpenStreetMap extract below. …

Once Southbound trains had crossed La Roya, it was just a short distance before they entered Gorges Paganini Tunnel. This is the tunnel mouth. [55]
Turning through 180° this is the view from the cab of a Northbound train leaving Gorges Paganin Tunnel (1,702 metres in length). [35]
Gorges Paganin Tunnel runs South-southwest parallel to the valley of La Roya and only a few metres beyond the valleys western face, occasionally running close enough to the valley side for gallery openings to shed light into the tunnel.
Gorges Paganin Tunnel is marked by the dotted line to the West of the river valley. It is over 1700 metres in length with occasional gallery openings in the valley side. [25]
The Gorges Paganin Tunnel is actually considered to be a series of six different tunnels separated by sections of galleries with arched openings into the valley side. These tunnels are: Foce (167m long); Tornau I (270m long); Tornau II (475 m long); Ravallone I (392m long); Ravallone II (91m long; and Balma (337m long). [1: p129]

OpenStreetMap shows a short length of line within the Paganin Valley above the Hydroelectric Power Station which is next to the E74/D6204 in the valley of La Roya. [26]
Google’s satellite imagery shows the hydroelectric scheme in the Vallon de Paganin and the power station next to the road and La Roya. The railway line can be seen just to the left of centre. [Google Maps, August 2025]
Banaudo et al tell us that at “the end of the tunnel, the line opens into the Paganin Valley, which marks the northern border between Italy and France. … In this wild and steep site, where a torrent and the penstock of the Paganin Hydroelectric Power Plant tumble, the portals of the last Italian tunnel and the first French tunnel face each other, each guarded by a roadside cottage in the typical style of the FS and PLM.” [1: p129]
Having reached the old French/Italian border we can stop and take stock. We will look at the construction of the line North from the coast once our journey reaches that portion of the line. Suffice to say that by 1915 tracklaying from the coast had reached Airole.
As far as the line heading South from Cuneo is concerned track laying had reached San Dalmazzo di Tenda and the structures and track formation was in place to the Northern French /Italian border.
2. The First World War
In 1915, Italy entered the war on the side of the allies. “Leading up to WWI, Italy had formed an alliance with the Central Powers of the German Empire and the Empire of the Austria-Hungary in the Triple Alliance. Italy should have joined on the side of the Central Powers when war broke out in August 1914 but instead declared neutrality.” [27]
“The Italian government had become convinced that support of the Central Powers would not gain Italy the territories she wanted as they were Austrian possessions – Italy’s old adversary. Instead, over the course of the months that followed, Italy’s leaders considered how to gain the greatest benefit from participation in the war. In 1915, Italy signed the secret Treaty of London and came into the war on the side of the Triple Entente (Britain, France, Russia). By its terms, Italy would receive control over territory on its border with Austria-Hungary stretching from Trentino through the South Tyrol to Trieste as well as other areas.” [27]
“After the war ended, at the Paris Peace Conference that led to the Versailles Treaty, the Italian government struggled against the other Allied leaders, the Big Three (Britain, France and the US), to gain all that they believed had been promised to them. Although Italy did receive control of most of the European requests, they failed to gain their colonial ambitions and felt they did not get what they had been promised. This engendered resentment towards the Allied countries, especially as Italians felt they had paid a high price, in terms of men and money, fighting for the Allies. These resentments helped drive the success of Benito Mussolini and his fascist movement – four years after the war, Mussolini and his blackshirts gained power.” [27]
Ultimately, the war stopped all progress on the line. Banaudo et el tell us that “the work begun thirty-two years earlier by the SFAI, then continued by the RM until nationalization, was thus virtually completed by the FS. The construction of the 80.3 km of line in Italian territory cost nearly 85 million lire compared to the 76 million initially planned, representing an average expenditure of 1,058,500 lire per kilometre.” [1: p135]
In France, the war caused all work to be halted. An attempt was made to continue the work in 1915, but failed because of underground conditions encountered. In 1917, an attempt to continue activity using prisoners of war was unsuccessful.
During the war, Italian authorities lifted track between Piena and Airole in the South for use on the front. Work on the new Cuneo railway station halted.
French and British troops were sent to augment Italian forces on 1917. It seems as though many of these passed through San Dalmazzo di Tenda. Between 19th October and 15th December 1917, “192 military convoys departed from San-Dalmazzo, and the Col de Tende line saw up to twenty movements of all categories on some days.” [1: p136]
After the war, resources were in short supply. In France priority was given to the devastated areas in the Northeast of the country. The PLM received very little support. Contractors found recruitment a problem because of the drastic loss of life among working age men. Banaudo et al tell us that in France “tunnels, abandoned for nearly five years, had suffered serious deformation, particularly in areas with high water infiltration. In Italy, the situation was no better, and construction of the new Cuneo station was suspended, even though an arch of the large viaduct over the Stura River, which was to provide access to it, was already being erected.” [1: p138]
Nevertheless, work did resume, supplies began to head North from Menton on the tramway to Sospel and supplies were arriving from the South via the FS on the Italian side of the border at Airole. Transport via Airole proved better than via the Menton-Sospel tramway and by 1920 the two main contractors on either side of the border (Giianotti and Mercier) ceased to use the Menton-Sosel route. [1: p138]
1920 saw a significant budget reduction for the works in French territory – 104 million Francs to 75 million Francs. Only 17 million Francs were allowed in 1920. “The Mercier company alone was spending 4 to 5 million francs per month on its construction sites.” [1: p140] Layoffs were necessary and work slowed significantly to remain within budget.
“In June 1920, the Inspector General of Public Works announced to companies that only 700,000 francs of credit remained to complete the year, an insignificant sum that forced construction to be suspended immediately, putting hundreds of workers out of work. Elected officials from the Alpes-Maritimes immediately rushed to Paris to meet with representatives of the ministry and the PLM management. After heated discussions, a new budget was allocated by the State for railway construction. The PLM had a credit of 41 million, 25 of which were allocated to the Nice – Cuneo line. Work could resume, but the engineers and contractors in charge of it would have to take into account the irregular arrival of funds until the end when organizing their construction sites.” [1: p140]
2. The Northern French/Italian Border South to Breil-sur-Roya
Two tranches of construction work covered the length of the line from the French/Italian border to Breil-sur-Roya. Banaudo et al tell us that this length of the line “contained the highest density of engineering structures on the French route, and, with a few exceptions, the war had interrupted work there in its early stages.“[1: p142]

The French engineer, Paul Séjourné decided to create a significant structure at the location of the Scarassoui Viaduct. Banaudo et al quote Séjourné: “The Scarassoui Viaduct is the first French structure that one will see when coming from Italy. It is like a gateway to France; it must be worthy of it.” [1: p142] Séjourné was of the opinion that: “Of all the structures — I mean all, even the smallest — appearance matters. It is not permissible to make ugly. It is a strange opinion to consider expensive what is beautiful, cheap what is ugly.” [1: p142] The bridge Séjourné designed was a curved viaduct (radius 300 metres) carrying the railway on a falling grade of 21 mm/m. It was 125 m long, spanning both La Roya and the E74/D6204 at a height of 42 m. Banaudo et all, tell us that “two arches of 11 m on the Nice side and a 13 m arch on the Cuneo side give access to a central arch of 48 m decorated with six vaults, according to a design that Séjourné had applied on other works. … The central arch was supported by two massive pilasters with crenellated facings, whose bases were widened to compensate for the misalignment due to the curvature of the deck.” [1: p142]
Sadly this bridge was destroyed by the retreating German forces in 1944 and it was not reconstructed in any form until the 1970s. Details of this bridge and photographs of its condition prior to reconstruction can be found here. [34] The replacement 1970s structure is shown below. …

Early during the construction of the bridge at Saorge. Here we see the formwork for the arch being constructed high above the valley floor, (c) Public Domain. [50]
Work on the bridge at Saorge started “in February 1922 from the Saint-Roch and Nosse tunnels, between which a conveyor cable was stretched for the assembly of the 40 m lowered arch. A suspended footbridge was then launched over the precipice and a 0.60 m track was placed there to supply the materials onto small 500 kg load wagons, maneuvered by gasoline-powered shunters. … The main work of the bridge was completed in March 1923.” [1: p143]
The bridge at Saorge was completed in 1922, it spanned the valley of La Roya at a particularly tight point along the gorge. The village of Saorge can be seen beyond the bridge. This bridge was destroyed by the retreating German troops in 1944. [47]This extract from a postcard image shows the bridge in use in the early 1930s.

The Eco Museum was founded in 1989 to showcase the history and heritage of the Roya valley, it became a museum focused mostly on industrial heritage in 1991. It now houses exhibits of hydropower and transportation. The collection comprises lots of interesting locomotives, railcars, trams, postal vans and other vintage vehicles.

We finish this fourth length of the journey from Cuneo to the coast of the Mediterranean here at Breil-sur-Roya South of Breil, there are two routes to the coast. One heads to Ventimiglia, the other to Nice. The next article will look at the line heading South towards Ventimiglia.
In Breil, the earthworks for the international station were constructed starting in June 1920. The area was around 1 kilometre in length and 300 metres wide. To build this the, “National Road 204 had to be diverted towards the Roya for about a kilometre, as was the Goulden power plant canal. The natural ground was cleared on the northern side and raised with excavated material from the tunnels on the southern half. At this end of the station, the modest single-arch bridge over the Lavina valley, which provides access to the Nice and Ventimiglia lines, required considerable work. The foundations for the abutment on the Nice side had to be dug into a gypsum bed sloping to a depth of 16 metres (compared to 2.20 metres on the Breil side, where hard rock quickly emerges). and a 15.12 m high reinforced concrete cantilever to the abutment anchored it in the loose fill.” [1: p141]

The first decade of the 20th century saw the existing roster of locomotives on the line South of Cuneo supplemented by two additional series :130s (UK, 2-6-0) tender locos of the FS 630 series; and 040T (UK, 0-8-0T) tank locos of the FS 895 series. The featured image for this article is one of the tank locomotives of the FS 895 series. [65]

The Line South from Vievola
Our journey South down the line continues from Vievola. …

Before we can head South from Vievola on the railway, it needs to have been built! This, it turns out, was dependent on international agreements and their ratification by national parliaments. This process was fraught with difficulty! It would take until 21st March 1906 for agreements to be ratified!
Banaudo et al tell us that over the final decades of the 19th century, the various interests on the French side of the border sought to persuade the French government that the line from Nice to Cuneo was an important investment which should be made. As a result, the French government “invited the PLM company to undertake a route study from Nice to Sospel in circular dated 30th September 1890, renewed on 28th January 1892, given the lack of response from the railway administration. On 12th May, a prefectural decree authorized the company’s engineers to enter properties to conduct the first surveys.” [1: p57]
Banaudo et al continue: “To meet the requirements of the Ministry of War, the route had to include Lucéram. This resulted in a 15 km extension of the direct route between Nice and Sospel. In 1895, the General Staff showed an initial sign of goodwill by agreeing to the study being extended beyond Sospel towards Italy, subject to certain conditions. On 19th April 1898, Gustave Noblemaire (1832-1924), director of the PLM company, submitted a preliminary proposal for a line from Nice to the border via the Paillon de Contes valley, the Nice pass, L’Escarène, the Braus pass, Sospel, Mount Grazian, Breil and the Roya valley. The Lucéram service was included as a branch line from L’Escarène, other solutions were not technically feasible.” [1: p57-59]
The military response arrived on 27th September 1899, when the principle of the branch line was accepted. It was a few months, 10th January 1900, before the military confirmed their requirements, specifically: “commissioning of the Lucéram branch line at the same time as the L’Escarène – Sospel section; construction of the extension beyond Sospel after reinforcing the installations at Fort du Barbonnet and orientation of the tunnel under Mont Grazian so that it could be held under fire from the fort in the event of war; development of mine devices and defensive casemates at the heads of the main tunnels between L’Escarène and the border; and authorization for Italy to begin laying the track from San-Dalmazzo-di-Tenda to Fontan only after the completion of the Nice-Fontan section by France.” [1: p59]
Cross-border discussions took place between the French departmental Bridges and Roads Department and “its counterpart in the civil engineering department of the province of Cuneo to determine the main technical characteristics of the railway line built by the RM between Cuneo and Vievola, in order to adopt equivalent standards for the French section in terms of grades, curves, and gauge.” [1: p59]
Banaudo et al continue: “At the dawn of the 20th century, while the choice of a route from Nice to the Italian border at San-Dalmazzo via the Paillon, Bévéra, and Roya rivers was no longer in doubt in France, the same was not true in Italy. Indeed, although this solution was preferred by Piedmontese business circles, it was opposed by multiple pressure groups weary of twenty years of French policy of opposition and uncertainty. For many localities on the Riviera or in the Ligurian hinterland, as well as for a persistently Francophobic segment of the general staff, the construction of a line entirely within Italian territory appeared to be the best way to avoid diplomatic and strategic complications.” [1: p59]
In Italy, Piedmont and Liguria had differing views about the appropriate railway routes. Piedmont secured a promise, in the Italian parliament, to extend the railway to Tende and a decision to connect it to the coast soon. In Liguria, the desire was to secure a connection to Ventimiglia via either the Roya Valley or the Nervia Valley. Serious consideration was given to a tramway in the Roya Valley, the central section of which would run through French territory but this was rejected by the French military. [14]
A number of alternative schemes were put forward by Italian interests and by the city of Marseille. The city of Turin appointed a commission to look at all the options and after its report “concluded that it preferred the most direct route via the Col de Tende and the Roya, towards Ventimiglia and Nice. Similarly, the French Chamber of Commerce in Milan supported this choice in March 1900, also proposing the construction of a new 47 km line between Mondovi and Santo Stefano Belbo, designed by the engineer Ferdinando Rossi to shorten the journey between Cuneo, Alessandria and Milan.” [1: p60-61]
In 1901, French and Italian diplomats and then the Turin authorities agreed the main principles for an international agreement. On 24th January 1902 the PLM was granted the concession for the railway from Nice to the Italian border via Sospel, Breil-sur-Roya, and Fontan, as well as the beginning of the line from Breil-sur-Roya to Ventimiglia. This was ratified by law on 18th July 1902.
After this a further military inspection led to the strategic Lucéram branch being temporarily left aside with the possibility of a replacement by an electric tramway from Pont-de-Peille to L’Escarène, to be operated by the Compagnie des Tramways de Nice et du Littoral (TNL).
Banaudo et al continue: “On Monday 6th June 1904, delegations from both countries met in Rome to sign the bipartite convention regulating the terms and conditions of operation of the future line and its implementation into international service. … In its broad outline, the agreement provided for the completion of the works within eight years (i.e. by 1912) and the possibility for the Italian railway administration to have its Ventimiglia-Cuneo trains transit French territory, with reciprocal authorization for the French operator to run its own vehicles in Italy on direct Nice-Cuneo trains and to establish a local service between Breil, Fontan and San-Dalmazzo-di-Tenda. … Initially, passenger services on the line would be provided by three direct daily connections Nice-Cuneo and Ventimiglia-Cuneo, and vice versa, offering carriages of all three classes.”
Banaudo et el describe the main points of the convention in respect of the transport of people and goods, particularly for transit between the two borders. “Police and customs controls would be simplified as much as possible for nationals of both countries. Nevertheless travelling between two Italian stations via the international section would require a passenger to have a valid passport. Italian postal vehicles would be permitted to travel duty-free on this section, as would goods and baggage in transit, provided they were placed in sealed vehicles and, for livestock, had undergone a prior health inspection at an Italian station. A special clause authorized the passage of Italian military transports of men, equipment, and animals through French territory, while conversely, the French army would be permitted to transit its consignments from Nice to Breil via Ventimiglia. Article 20 of the convention regulated a legal situation that was probably unique in Europe, that of the Mont Grazian tunnel, whose straight route would pass over a distance of 2,305 metres in Italian subsoil, although its two portals would be in France: ‘It is understood that for the part of the Mont Grazian tunnel located under Italian territory, the Italian government delegates to the French government its rights of control over the railway and its police and judicial rights’. This unusual situation resulted from a modification of the route decided at the request of the General Council of the Alpes-Maritimes. … This more direct route passing under Italian soil was finally preferred to the entirely French route under the Brouis pass, which would have been longer and would have moved the Breil station further from the village.” [1: p62-63]
In Italy, the ratification of the agreements made at the convention took three weeks – it was all done by 28th June 1904. In France thins would be quite different. “On 27th March 1905, as the convention was about to be submitted to a parliamentary vote, the Ministry of War decided to abandon the branch line to Lucéram, which was too costly and difficult to implement. Instead, the nearest stations, L’Escarène and Sospel, would need to be equipped with facilities for the rapid disembarkation of troops and equipment. At L’Escarène in particular, the station would need to be able to accommodate ten twenty-car trains per day and would have to include a military platform opening onto a large open area, an engine shed, and several water columns/supplies. In addition, the road from L’Escarène to Lucéram would need to be improved to facilitate access to the defensive sector of L’Authion.” [1: p63]
Banaudo et al comment: “The French Chamber of Deputies finally ratified the agreement on 3rd July 1905, more than a year after its Italian counterpart, but the Senate would continue to procrastinate until 8th March 1906. The senators demanded financial participation from the Alpes-Maritimes department in the land acquisition costs, and the French Consul in Italy, Henri Bryois, made numerous appearances in Paris to convince them. The day after the Senate’s vote, on 9th March 9, a parade, speeches, and demonstrations of sympathy for France enlivened the streets of Cuneo. … On 20th March, a final law officially ratified the agreement. … The municipality of Nice organized a grand celebration to celebrate the culmination of fifty years of effort. On 21st March 1906, Prime Minister Giolitti and Ambassador Barrère exchanged the documents ratified by the parliaments of both countries. Work could finally begin!” [1: p63]
In Italy, the ratification of the international convention led to the money for the completion of the works being set aside (24 million lire for the length South from Vievola to the then border, and 16 million lire for the length North from Ventimiglia to the southern border). In addition, the decision was taken to build the new station in Cuneo to accommodate the increased traffic that would arise from the new line.
A year later, on 1st July 1905, the Italian state brought all nationally significant rail routes/networks under the direct authority of the Ministry of Public Works (the Ferrovie dello Stato (FS)). This had only a limited impact on the Cuneo-Vievola line. “The 3200, 3800, and 4200 series locomotives of the Rete Mediterranea now formed series 215, 310, and 420 of the [FS}. … At that time, the Torino depot had a complement of 128 locomotives, including 20 from the 215 series and 18 from the 310 series deployed in the line, to which were added ten locos from the 320 series. These were also 030s [in UK annotation, 0-6-0s] with three-axle tenders, initially ordered by the RM as series 3601 to 3700 and gradually delivered by five manufacturers between 1904 and 1908.” [1: p64]
The first decade of the 20th century saw the existing roster of locomotives supplemented by two other series:
130s (UK, 2-6-0) tender locos of the FS 630 series; and
040T (UK, 0-8-0T) tank locos of the FS 895 series.
Locomotive No. 6301was a 2-6-0 (130) locomotive in the FS 630 series. [64]Locomotive No. 8955 was an 0-8-0T (040T) locomotiv3 in the FS 895 series, [65]
In 1906, a subsidised bus service was introduced to complement and replace the various horse-drawn and motor services already in existence on the roads between Vievola, Ventimiglia and Nice. [1: p64][c.f. 14] The connection to Nice was later (in 1912) taken over by the Truchi company of Nice. [1: p64]
Vievola to Tende
Banaudo et al, again:“In August 1907, the first of eleven work packages between Vievola and the [then] border were awarded: package 1 from Vievola to the Gaggeoetlen tunnel, and package 4 of the Cagnolina tunnel to Tenda. In June 1911, it was the turn of package 2, between the Gaggeo and Alimonda tunnels, and the following month, package 3 from Alimonda to Cagnolina. These contracts were signed with the Tuscan companies Sard and Faccanoni and the Ghirardi company, originally from the region of Lake Maggiore. Over 8.2 kilometres, the line crosses Triassic and Permian terrain cut by Jurassic, Cretaceous, and Carboniferous veins. There are ten tunnels covering a distance of 5.90 kilometres, or 72% of the route, as well as seven bridges and viaducts totaling seventeen masonry arches. The section has no level crossings, but seven “caselli” (houses) were built to house the road workers and their families. Some are isolated in the mountains, sometimes between two tunnels, and accessible only by railway.” [1: p64-67]

[Google Maps, July 2025]
From Vievola, the line begins its journey down the valley of La Roya by crossing a single-arch bridge over the Dente valley which suffered some disruption resulting from Storm Alex in October 2020.

The tunnel opens onto the right bank of La Roya about 25 metres above the river. The Vievola Viaduct spanned the river on five 15 metre masonry arches. Banaudo et al tell us that, “this structure would later be called the ‘Chapel viaduct’ due to its proximity to the Sanctuary of the Visitation or Madonna of Vievola.” [1: p67]

I believe that the viaduct was fatally damaged by the German forces retreating at the end of WW2. It has been rebuilt in concrete as a 5-span concrete viaduct.

Now on the left bank of La Roya, the line passes through a series of tunnels with very brief open lengths spanning narrow valleys or slight depressions. The first tunnel on the Left bank is shown below. …
After crossing the Chapel Viaduct trains heading for Tende ran straight into Gaggio Tunnel (373 metres long) which curves towards the Southeast. [20]

The tunnel portals are generally made of local stone as are the arched bridges. The next tunnel is the Devenzo tunnel, shown below. …
The Devenzo Tunnel (732 metres long) extends Southeast from the San Pancrazio valley to the Mezzora Valley which seems little more than an ‘indentation’ in the valley side. A shorter tunnel is beyond the opening (the Mezzora Tunnel – 351 metres long) which opens out onto the Alimonda Valley at the bottom-right of this map extract. [22]
This photograph is another still from a video taken from the cab of a train travelling North from Tende. It shows the short length of open line mentioned above. The parapets are those of the viaduct of two 6 metre arches. [35]
This Google Earth satellite image shows the railway line breaking cover to cross the Alimonda valley near the top of the image. The E74/D6204 is at the bottom-left of the image. [Google Earth, July 2025]The same location as it appears on OpenStreetMap. The bridge over the Alimonda valley is at the top-right of the image and the E74/D6204 is in the bottom-left. [24]
The Southeast portal of the Mezzora Tunnel can be seen in this image taken from the tunnel mouth of the Alimonda Tunnel. It is possible to see along the full length of this tunnel to the short opening mentioned above. In the course of travelling this short length of open line the railway crosses the Alimonda Valley. [35]
The next tunnel, the Alimonda Tunnel begins immediately the Alimonda valley has been crossed. The tunnel is 380 m long.
The Alimonda Tunnel: the bridge over the Alimonda Valley is top-left in this map extract, the bridge over the Scara Valley is bottom-right. [25]The bridge over the Scara Valley is on the right of this map extract. There is very little of the railway open to the elements at this location. [26]
The short length of track and bridge in the Scara Valley between the Alimonda Tunnel and the Frera Tunnel, seen from the cab of a service which has just left the Frera Tunnel heading for Vievola and on to Cuneo. [35]
Before entering the Frera Tunnel, it is worth pulling back a little to see the route of the line ahead. This is the first ‘spiral’ on the line down towards Ventimiglia and Nice. A large section of the spiral is within one tunnel but the engineers made use of the Valley of the Refrei to avoid having to put the entire spiral in tunnel. [36]
The Frera Tunnel (498 m long) runs North-northwest to South-southeast passing over the line ahead which is at a lower level – both are tunneled out of the rock. There is an open length of the line and a bridge at the bottom-right. [27]
The short length of track and the bridge between the Frera and the Rio Freddo tunnels. [35]
After crossing the bridge noted above the line soon disappears into the Rio Freddo Tunnel (376 m long). The bridge is top-left. The tunnel opens out for a short length at the right of this map extract. [28]A short length of line is open to the elements to the North of the valley of the Refrei and between the Rio Freddo and Morga Tunnels. [29]
The short length of line between the Rio Freddo and the Morga Tunnels, seen from the cab of a train just leaving Morga Tunnel. The Rio Freddo tunnel mouth is ahead. Between the two tunnel mouths is the Morga Bridge (two 8-metre arches). [35]
Banaudo et al tell us that “from the exit of the Rio-Freddo tunnel [on the North flank of the Refrei valley], the village of Tenda (Tende) appears below and the railway describes a helical loop which ends at [the lower end of] the Cagnolina tunnel. … This loop loses about sixty metres of altitude in less than 3 km of travel.” [1: p70]
After the very short open length of line to the East of the Rio Freddo Tunnel, another short tunnel ensues – the Morga Tunnel (160 m long). [30]Another short open length of line sits between the Morga and Gerbo Tunnels. [31]
The short open length of track between Morga and Gerbo tunnels, seen from the cab of a Cuneo-bound service and framed by the Southwest mouth of Gerbo Tunnel. [35]
Pulling back a little enables the full length of Gerbo Tunnel (279 m long) to be seen, together with the open length of line and viaduct to the East – Gerbo Viaduct. [32]
The Northeast Portal of Gerbo Tunnel seen from the cab of a Cuneo-bound train in the 2020s. [35]
A short distance further along the line, the Bazara Viaduct (of five 8 m arches) is seen here, with the Gerbo Tunnel beyond – these are seen from the cab of a Cuneo-bound service in the 21st century. [35]
After a short length of line to the Northeast or Gerbo Viaduct the line enter Cagnolina Tunnel and under many tons of rock swings round to travel West while on a downward grade. [33]
Here the Cuneo-bound train is just leaving the South Portal of Cagnolina Tunnel (at the right of the above map extract) and crossing a small bridge close to the tunnel mouth. [35]
Still in tunnel, the line passes under the line we have just travelled before breaking out into the valley of La Roya. It then bridges the river and heads down the the valley side on the left bank of La Roya to Tende Railway Station. [34]

A train from Cuneo arrives at Tende Railway Station in February 2023. [37]
The Tende Railway Station today has a passenger building and two platform faces. In the past, it had three platform faces and a goods shed of classic Italian design, “the station had a number of goods tracks, two reinforced concrete water tanks supplying two hydraulic cranes, as well as an 8.50 metre turntable which was probably transferred from Vievola when the line was extended.” [1: p70]
Wikipedia tells us that Tende Railway Station “opened on 7th September 1913. [40: p146] … Tende remained the temporary terminus for almost two years, until the opening of the Tende – Briga Marittima – San Dalmazzo di Tende section, which took place on 1st June 1915.” [39][40: p149]
The station and yard were electrified along with the line in 1931. [40: p171-172]
Tende “became isolated from the railway network after the destruction of bridges and tunnels by the retreating Germans between 15th and 26th April 1945.” [39][41: p15] .
“It remained under the jurisdiction of the Italian State Railways (FS) until 15th September 1947 and was passed into the hands of the Société Nationale des Chemins de fer Français (SNCF) the following day, when the upper Roja valley was separated from the province of Cuneo and became French territory by virtue of the peace treaty with France.” [39]
“After thirty-four years of inactivity, it was reopened on 6th October 1979 , the day of the inauguration of the rebuilt Cuneo-Ventimiglia line.” [39][40: p243]
The station yard was originally of a significant size. [42: p81] For the reopening of the Limone-Ventimiglia line to traffic … it was initially planned that the Tende station would be transformed into a stop equipped with only a single track, but it was subsequently decided to build a loop [43: p34] with a useful length of 560 metres and a single track serving the loading platform and the goods warehouse. [43: p29]

We have travelled as far as Tende Railway Station and noted that the line reached the village in 1913 and remained the terminus of the line from Cuneo until 2015. While the line as far as Tende was still under construction, Banaudo et al tells us that there were continued contacts “between the Italian and French authorities to resolve the remaining issues concerning the connection between the two networks in the Roya Valley. On 3rd January 1910, the Ministers of Public Works of both countries … met to discuss the problems of Franco-Italian communications. On 15th May 1910, the Cuneo Chamber of Commerce approached the government to request the acceleration of work between Vievola and Tenda. … During the same period, … efforts were being made to produce [hydroelectric power]. … The first plants were installed in Airole and Bevera in 1906, and later in San-Dalmazzo between 1909 and 1914.” [1: p70-74]
“The Roya hydroelectric power plants were intended to supply the Vallauria Mining Company and its ore processing facilities, public lighting, industries and the tramways of the Ligurian Riviera as far as Savona and Genoa.” [1: p74]
In France, two small power plants were built at the beginning of the century at Pont d’Ambo, downstream from Fontan, and in Breil. Between 1912 and 1914, a larger power plant was built opposite the village of Fontan.
Banaudo et al tell us that “In both France and Italy, the simultaneous construction of the railway and power plants turned the Roya Valley into a huge construction site for a dozen years. The companies had to house, feed, and entertain several hundred workers, most of them from other regions of Italy.” [1: p74]
After the opening of Tende Railway Station in September 1913, “the FS improved the service which had remained unchanged for a quarter of a century. Four Cuneo – Tenda return trips would now run every day, including a mixed goods-passenger one. From July to September, a fifth return trip was added. The 50 km journey took an average of 1 hour 50 minutes.” [1: p75]
Meanwhile, the project to divert the railway line and build a new station on the Altipiano in Cuneo which we noted in the first of these articles, [9] was being developed. Work began in September 1913 [1: p80] but it was to be 7th November 1937 before the new station opened! [44]
“While the line was creeping southwards from Cuneo to Tenda, work had begun in Ventimiglia on the northbound line up the Roya Valley. However, by the outbreak of World War I it had only covered 20 kilometres to Airole. Meanwhile, and again interrupted by the war, another line was being built northeast from Nice to join the Cuneo-Ventimiglia line at Breil sur Roya.” [39] Progress on these two lines is covered in other posts in this series of articles. [45][46][47][48]
From Tende to St. Dalmas de Tende(San Dalmazzo di Tenda)
“In the first half of 1912, calls for tenders were issued for six lots of the section between Tenda, Briga, San-Dalmazzo, and the northern border of the Paganin Valley, followed in April 1913 by the award of the seventh and final lot. Here again, the tunnels, fifteen in number, account for more than two-thirds of the route, or 8,576 metres out of 12,335 metres. There are also seven bridges and viaducts, comprising a total of thirty-five masonry arches, about ten short-span structures, and there were ten roadside houses.” [1: p127]

The next tunnel is Bosseglia Tunnel. The railway and the main road separate as the line heads into the tunnel which is S-shaped and 1585 metres in length. The southern portal of the tunnel opens out into the Levenza valley, a short distance to the East of La Brigue Railway Station. Banaudo et all refer to the station as Briga-Marittima station, which appears to be the name of the station in Italian. [1: p127]

Beyond the Levenza Tunnels is and an unnamed viaduct of three 8-metre arches) and the line then enters the Rioro Spiral Tunnel.
The Rioro Tunnel forms a loop which describes a circle of 300-metre radius and accommodates a 30-metre drop.
Banaudo et al tell us that the tunnel “is officially divided into two sections: Rioro I (282 m) and Rioro II (1527 m), connected by an artificial tunnel with a lateral opening closed by a gate. At this opening, a ‘casello’ (a ‘hut’) was built into the mountainside to house a road worker and his family.” [1: p127]

To the Southwest of the tunnel, the line is carried alongside the River Levenza on a retaining wall. The parapet of this wall, protected by railings, can be seen on the right of this image. [55]
The River Roya is crossed by the San-Dalmazzo I viaduct. Banaudo et al tell us that “the seven 15-metre masonry arches of this structure were widened to carry three tracks to accommodate the approach to the station, built on a vast embankment. An underpass beneath it provides a route for the [E74/D6204].” [1: p127]
The line is retained above the Levenza River and then crosses La Roya on a viaduct of seven 15-metre masonry arches. A short tunnel under the wide embankment to the Southwest of the river allows the D6204 to pass under the railway. [61]

St. Dalmas de Tende (San-Dalmazzo-di-Tenda in Italian) was “the last station on Italian territory, before the northern border. This is where the French Forces would install a large-scale border station that will handle customs clearance operations in addition to the French facilities at Breil. In the first phase, a temporary passenger building and a small freight shed were built on the vast embankment created from the spoil from the tunnels upstream of the confluence of the Roya and Biogna rivers. The original layout includes four through tracks, one of which is at the platform, five sidings, three storage tracks, a temporary engine shed, a 9.50 m turntable, and a hydraulic power supply for the locomotives.” [1: p127]
It is here, at St. Dalmas de Tende, that we finish this third part of our journey from Cuneo to the coast.
Located at the confluence of the Roya River with the side valleys of the Levenza and Biogna, San-Dalmazzo-di-Tende “was built around a former Augustinian convent that became offices of the Vallauria mining company and then a spa. Since the border was established in 1860 a few kilometers downstream in the Paganin Gorges, first a few dozen, then hundreds of workers, employees, and civil servants gradually settled in San-Dalmazzo with their families. Jobs were plentiful, with the development of mining in the neighboring Val d’Inferno, the creation of a sawmill, the construction of dams and hydroelectric power plants, the emergence of tourism, and the permanent presence of a large number of police, customs, and tax guards. This influx … was reinforced during the railway works, which attracted many workers: earthmovers, masons, stonemasons, miners, carpenters, etc. These newcomers, who mostly came from other regions, sometimes far away, slowly integrated into the local population.” [1: p130]
The line to San-Dalmazzo-di-Tende was opened on 1st June 1915. The three of the four daily services were connected to the Southern arm of the line which by this time had reached Airole, by a coach shuttle. [1: p131]
A temporary station was provided as a terminus of the line from Cuneo. It was sited to the Northeast of the present large station building which was not built until 1928.
The next length of the line can be found here. [67]

A proposed tramway that did not get built. … The featured image is a map showing the full length of the proposed line which followed National Route No. 204 in France.
Late in the 19th century before a link from Vievola to the Mediterranean was really on the agenda. Alongside the experimental ‘Train Scotte’, [1: p40][2][3] a “local engineer, M. Chatelanat, proposed building a tramway line between Vievola station … and Ventimiglia. He knew the region well, having just overseen the construction of the rack railway from Monte Carlo to La Turbie. [4] Here is the project he presented in an application filed on 7th February 1899.” … [1: p47]
The submission made by M. Chatelanat began, “The electric tramway for which we are requesting a concession is intended to facilitate the movement of passengers and goods in the Roya Valley through a rapid, convenient, and economical means of communication. Currently, to reach Nice and the other communes of the department, the population of the French part of this valley must either travel more than 60 kilometers along the old Nice-Cuneo road, crossing the foothills of Brouis and Braus, in unsafe conditions due to the steep slopes, the height of the passes, and, in winter, the seasonal inclement weather. Or, since the opening of the national road from Breil to Ventimiglia, travel approximately 30 kilometers and cross two customs lines to join the coastal railway line in Ventimiglia. … Between the coast and Upper Piedmont, especially the province of Cuneo, there is a very intense movement of population every year, but if you want to go by train, you have to make a long detour via Savona, which is long and expensive. The province of Cuneo sends to Nice and the coast some of its products that our region cannot obtain elsewhere. On the other hand, our particular products from the South are in demand and consumed in the upper Po Valley. Facilitating the movement of travelers and this exchange of products between Piedmont and the coast will at the same time allow the French populations of the Roya Valley to come easily and quickly to Nice to stock up and connect with the entire French coast without having to cross the Braus and Brouis passes, such is the goal we are pursuing.” [1: p47]
There were a number of projects of this nature being explored at the time. The tramway between Menton and Sospel is an excellent example. [5][6] Others in the valley of the River Var and in the valley of the River Paillon were also built.
M. Chatelanat continues to explain how up to that time it had not been possible to devise a railway scheme that enable a link between Nice and Cuneo. His proposed tramway was not claimed to be a replacement for the planned railway, but while awaiting the development of the railway scheme, the tramway would “provide great services by greatly reducing the communication difficulties between the two regions. The project [would] not provide the speed of the railway, it [would] require two transshipments at Ventimiglia and Tende. Nevertheless, the transport of goods [would] be significantly more economical and passengers [would] find facilities and comfort there which [would] undoubtedly give the population satisfaction, if not complete, at least acceptable. The electric tramway, executed at a width of 1 metre with gradients of up to 70 mm/m and curves down to 20 metres in radius [could not] be used for the passage of standard-gauge locomotives and wagons, and therefore [could not] be used in the event of war.” [1: p48]
Concern about possible conflict was paramount in the minds of many and projects were vetted and often vetoed by the military. M. Castelanat went on to explain that power for the section of the line would be supplied from a hydraulic plant close to Breil-sur-Roya which could easily be put out of action, and if the overhead cables were also removed no use would be possible. He was sure that no advantage would be gained by a future enemy and that “The tramway must therefore be considered a commercial means of communication with no possibility of use in the event of war.” [1: p49]
Castelanat confirmed that electrical operation would mean no problem would be encountered with gradients up to 7% without the need for any regrading of the highway. He planned stations at Breil, Giandola, Saorge, Fontan, and Berghe. The tramway would use National Road No. 204 without any deviations and would cost around 1,400,000 francs. This tramway would, strictly speaking, be only a section of an international line which would have its origin in Ventimiglia and which would go up the valley of the Roya.
A conference including all the statutory interested parties was arranged for 23rd November 1899. Differing views were expressed about whether the tramway could provide a military advantage to the enemy in the case of war. A few months after the conference, on 2nd May 1900, “Chief Engineer Aubé of the Ponts et Chaussées (Roads and Bridges Department) reached the following conclusions: ‘The establishment of the planned electric tramway has lost much of its appeal since the military authorities ceased, with certain reservations, to oppose the construction of the railway from Nice to Sospel and to the Italian border, near Fontan. This line would, in fact, provide the French population of the Roya Valley with the access to Nice they were willing to seek in an economical manner by means of the tramway connecting them to the international station at Ventimiglia‘.” [1: p50]
The effect of the military’s withdrawal of their opposition to the Nice-Sospel-Fontan line was to render the tramway proposals obsolete. It was 1904 before “an international conference finally approved the construction of the Vievola – Breil – Ventimiglia and Breil – Sospel – Nice railway sections. … [Nevertheless] two tram lines were created[in the area]: one from Menton to Sospel, which operated from 1912 to 1931, [5][6] and a line from Ventimiglia to Bordighera, which operated from 1901 to 1936.” [1: p50]
Instead of the ‘Train Scotte’ and a tramway, from perhaps as early as 1900, but definitely by 1st September 1906, a service connecting with trains was introduced between Vievola station and Ventimiglia. The two images below show the mixture of different vehicles in use. Both focus on the road on the West side of the station building at Vievola.
Banaudo et al provide details of a bus service which started on 1st September 1906. The bus service between Vievola and Ventimiglia provided two buses a day from Vievola to Ventimiglia, the first leaving Vievola at 12:15 and arriving in Ventimiglia at 17:00, the second leaving Vievola at 20:40 and arriving in Ventimiglia at 0:40. The cost of the full journey was 5 lire/person. [1: p52]
The advert in the local paper commented that, “Without making the tedious Bastia-Savona detour, travelers can reach the Nice or western Ligurian coast from Cuneo and nearby towns in just a few hours, take care of their business, and return to their hometowns the same day, if they wish, even finding enough time in Vievola to refuel. Every modern comfort will be available in the station buffet, since, with appropriate consideration, the owner, Mr. Giuseppe Borgogno, has asked the Italian State Railways Administration to expand and repurpose the space for this purpose.” [1: p52]
Banaudo et al share details of services which developed over the next few years with pictures of the various buses in use. [1: p52-56]

Société des Chaudières et Voitures à Vapeur système Scotte was a French manufacturer of steam-powered trucks, tractors, and omnibuses in Paris from 1893 to circa. 1914. The company also built the Train Scotte, an early road train for passenger or freight transport. [1]
I first encountered the Train Scotte when reading about the Cuneo-Ventimiglia-Nice international railway line in a book by Jose Banaudo, Michel Braun and Gerard de Santos; Les Trains du Col de Tende Volume 1: 1858-1928. [2] The partial opening of the that railway from Cuneo to Vievola in October 1900 left travellers heading for the Mediterranean in the middle of nowhere!
An experimental steam road train was trialled on the roads from Vievola to Ventimiglia. It was supplied by Société des Chaudières et Voitures à Vapeur système Scotte.
At this time, Vievola was a railway terminal for traffic to and from Piedmont and a hub for road connections onwards to Nice and Liguria. Banaudo et al point us to a magazine published in 1899, which mentions a trial of a steam-powered road vehicle which it was hoped would provide a service to Nice and the coast until such time as a railway was built. [1: p40][37] The service was a trial organised by the House of Ascenso et Cie, and ran from Vievola to Ventimiglia. The journey, lasted a total of six hours, including a 43-kilometre climb. The vehicles used were Scotte trains. The car wagon carried a 27-horsepower engine and seated 16 passengers; it also towed a second 24-seater wagon. [2: p40]
Industrialist Joanny Scotte, [10] originally from Epernay in the Marne department, began his business in the mid-1880s producing steam-powered cars. From 1897, he offered road trains consisting of a tractor or a steam-powered car, pulling one or more trailers designed for the transport of passengers or goods. These vehicles travelled on roads using solid tires. They never really went beyond the experimental stage due to their slowness, the difficulties of driving the vehicles on the narrow roads of the time and the damage caused to the cobbled and cylindered roads. [2: p40] Scotte road train services were reported in the last decade of the 19th century in the Île-de-France region (Fontainebleau, Pont-de-Neuilly, Courbevoie), in the Aube region (Arcis-sur-Aube – Brienne-le-Château), in the Manche region (Pont-l’Abbé-Picauville – Chef-du-Pont), in the Drôme region (Valence – Crest), and for military use. Scotte partnered with the Lyon-based car manufacturers Buire and Audibert-Lavirotte to produce some of its vehicles. [2: p41]
1. A power car (steam omnibus) capable of carrying fourteen passengers and the two engine crew; Weight of the empty car with all equipment: Motor: approximately 3,500 kg; Total length: 5m 20 cm; Width at the waist: 1 m 80 cm; and
The wikipedia webpage relating to the ‘Train Scotte’ provides a series of photographs and drawings of the company’s products, including one advertising poster. All are in the public domain and are shown below:
The tractor was equipped with a vertical Field system boiler, 600 litres of water for which were stored under the passenger seats, and a 14 horsepower, 2-cylinder engine. Coke or coal was its fuel (200 kg for 4 hours of operation). The movement was transmitted to the rear axle by a chain. The trailer was coupled to the tractor by a pivoting front axle. To stop, the steam omnibus had a quick brake operated by a pedal, a screw brake operated by a flywheel and, in an emergency, could work on the gear change. Steering was provided by a steering wheel. [9]
The Train Scotte train ran on wooden spoked wheels with iron tires. The seats were also made of wood, passengers needed to bring a cushion. The machine was quite noisy. It could be heard coming from afar and some houses shook as it passed. Its speed wasn’t very high, 12 to 15 km/h, so there was time to admire the scenery.
When carrying only goods, up to 5 to 6 tons, its speed was reduced to 6 to 7 km/h.
The experiment failed. The attempt to use the ‘Train Scotte’ between Vievola and Ventimiglia was abandoned quite quickly, probably no more than a few weeks after it commenced: driving was difficult, damage to road surfaces occurred, the road gradients were steep. [2: p41]
Elsewhere, experimental journeys had mixed success. Steam road vehicles were slow and they faced serious competition from similar vehicles with internal combustion engines. For a very short time around the turn of the 20th century, these vehicles seemed to have a future but ultimately the experiment failed!

Contrary to what one might think, the name Scotte is not of English origin, but entirely French. Mr. Scotte was previously called Mr. Crotte. Tired of the dubious jokes, he had an S added before the C, then removed the R from the patronymic spelling of his name. [9]

The Line South from Vernante to Limone
A schematic drawing showing the main locations on the line from Vernante to Limone. [17]
Banaudo et al write that “It was only in 1886, after the creation of the Rete Mediterranea, that the work on the fourth tranche from Vernante to Limone was awarded. It was 8,831 m long and had a gradient of 203 m, which was to be compensated for by a continuous ramp of up to 26 mm/m. This value would not be exceeded at any other point on the line. On this section, the rail remained constantly on a ledge on the steep slope on the right bank of the Vermenagna, where it was anchored by eleven bridges and viaducts totaling sixty-three masonry arches, as well as nine tunnels with a combined length of 4,416 m, or just over half the route:” [1: p28]
the Tetti-Chiesa tunnel which is 122 m long;
the Elicoidale tunnel (the Vernante Spiral tunnel) is 1,502 m long;
the Rivoira viaduct has fourteen 15 m arches and one 23 m arch;
the Rivoira tunnel is 251 m long;
the Santa Lucia viaduct has three 12 m arches;
a short span masonry arch over a minor road;
the Santa Lucia-Noceto tunnel is 348 m long with two openings;
the Noceto viaduct has six 8 m arches;
the Marino viaduct has two 8 m arches and two 12.50 m arches;
the Marino tunnel is 202 m long;
the Mezzavia viaduct, three 11 m arches;
the Mezzavia tunnel is 444 m long;
the bridge over the Ceresole valley has two 10 m arches;
the Boglia tunnel is 1,086 m long;
the San Bernardo viaduct over the Sottana valley has two 6 m arches and three 10 m arches;
the Cresta-Molino tunnel is 335 m long;
the Boschiera viaduct has twelve 10 m arches;
the Rocciaia tunnel is 126 m long;
the Rocciaia bridge is a single arch;
the first Rocciaia viaduct has four 8 m arches;
the second Rocciaia viaduct has eight 8 m arches.
We start this next length of the journey at Vernante Railway Station and head Southeast.

Photographs showing the station building and the goods shed prior to its demolition can be seen here. [58] “Inaugurated in 1889, the station served as the terminus for the Cuneo-Ventimiglia line for nearly two years, until it was extended to Limone Piemonte. The passenger building features classic Italian architecture, with two levels. It is square, medium-sized, and well-maintained. Its distinctive feature is the two murals depicting scenes from the Pinocchio fairy tale, adorning its façade. The lower level houses the waiting room and self-service ticket machine, while the upper level is closed.” [58]

The large retaining wall on the left of this image supports the railway as it runs immediately adjacent to the E74/SS20 but at a higher level. [Google Streetview, June 2025]The height of the retaining wall decreases as the E74/SS20 gains height. [Google Streetview, June 2025]
Banaudo et al comment: “Leaving Vernante, the track describes a complete spiral loop at Rivoira, which allows it to rise about fifty metres over a circular length of two kilometres. This loop includes the 1,502 m long ‘Elicoidale’ tunnel, which was completed on 30th December 1889, and the imposing viaduct over the Salet torrent. With its fifteen arches, from the top of which the rail dominates the lower level of the loop by 45 m, this structure can be considered by its proportions as the most imposing of the whole of line. [25] It is built entirely of cut stone, with the exception of the intrados of the arches which are of brick, and its seven central arches are reinforced at their base by a series of arcades forming an additional level, following a technique very popular in the 19th century.” [1: p30] The lower arcades are seen clearly in the 1929 postcard below.
This photograph is taken from the road at the point that the E74/SS20 begins to turn away from the lower railway (which can be glimpsed through the undergrowth) the viaduct high above both the road and the railway comes into view. This view looks North from the E74/SS20. A spiral tunnel allows the railway to gain height at this location. [Google Streetview, June 2025]This satellite image shows the portals of the Spiral tunnel to the East of Vernante. The line leaves Vernante Station and passes through a short tunnel before running alongside the E74 ‘Corso Torino’ to another tunnel mouth to the West of the side road. The line then climbs as it circles under that road twice and reappears high above the first length of line towards the top-left of this image. The height gained then means that the line needs to pass over a high viaduct before once again entering a tunnel (the Rivoira Tunnel) and then, at the bottom-right of the image, crossing another side valley on a bridge. [Google Maps, July 2025]OpenStreetMap shows the same location and illustrates the spiral tunnel quite well. [44]The lower portal of the spiral tunnel with the high viaduct (Rivoira Viaduct) visible to the left. [11]

The Boglia Tunnel carries the line around a significant curve. This is the South-southwest portal of the tunnel from the cab of a train which has recently left Limone. Trains from Cuneo enter the tunnel traveling East and leave in a south-southwesterly direction. Just beyond the South-southwest portal the line bridges another side road serving a number of hamlets. It is the San Bernardo viaduct over the Sottana valley. [8]
The bridge shown in the image immediately above is at the centre of this satellite image. The tunnel to the North-northeast is Boglia Tunnel, that to the South-southwest is Cresta Molino Tunnel. [Google Maps, July 2025]
Looking East along the Sottana Valley, it is difficult to believe that the San Bernardo Viaduct has two 6 m arches and three 10 m arches, it is so well camouflaged by vegetation. [Google Streetview, June 2025]Looking West along the road through the structure, it is possible to see three of the five arches. [Google Streetview, June 2025]
The Cresta Molino Tunnel curves throughout its length (see below). Towards the South portal, it has an open gallery facing out into the valley. [8]

After a very short length of track open to the elements, the line enters another short tunnel, the Rocciaia Tunnel. This tunnel is also on a curve with the line leaving the tunnel heading Southeast. [Google Maps, July 2025]

The length of the line from Rocciaia Tunnel to the station throat at Limone is shown on the satellite image below. The parapet railings associated with the Rocciaia Bridge can be seen on the image of the South portal of the tunnel above. There are then two viaducts, as shown on the satellite image below. They cast shadows onto the valley side to the east of the line.

Express services took 1 hour 30 minutes to travel from Cuneo to Limone, mixed goods and passenger trains were scheduled to take 2 hours. Services from Limone to Cuneo were scheduled for 1 hour 20 minutes and 1 hour 50 minutes respectively [1: p31]
Banaudo et al tell us that a single third class ticket between Cuneo and Limone cost 1.65 lire. The service was deemed to be a local service and as a result the RM allocated older stock to the line, “consisting mainly of single-axle coaches, side door stock, and brake vans acquired from other companies. Traction was provided by 030 [in the UK these would be 0-6-0] locomotives coupled to two- or three-axle tenders, from the RM 3201 to 3550 series (future 215 FS Class),” [1: p31] out-stationed to the Cuneo shed by the Turin Shed. These locos had a range of different manufacturers in Italy, France, Belgium, Great Britain, Austria and Germany. [1: p31]
The construction costs for the length of line from Cuneo to Limone “did not exceed 10 million lire, a remarkable figure given the difficulty of the work and the number of engineering structures completed over nine years: nineteen bridges and viaducts, fourteen tunnels, and a large number of culverts, aqueducts, road overpasses and underpasses, and level crossings. The buildings of the seven stations are of classical design, conforming to the standard plans with hipped roofs used in Italy, as are the twenty-four ‘caselli’, roadside houses, distributed along the line near the level crossings and the main underpasses to house the track maintenance workers and their families. The bridges and viaducts, with the exception of two brick structures, are made of stone masonry with brick arch vaults and metal angle railings. The single track tunnels are lined with brick vaults and dressed stone portals, except where the solidity of the ground allows the exposed natural rock to be preserved.” [1: p32]
Banaudo et al note that “the first years of operation were not easy, … snow and falling rocks sometimes hampered train traffic. On 2nd October 1898, following torrential rains in the high valleys of Piedmont, the Gesso overflowed and the bridge between Boves and Borgo-San-Dalmazzo was destroyed. By December, the installation of a temporary wooden bridge by contractor Salvatore Vignolo of Genova-Sampierdarena allowed service to be restored. A permanent structure would be rebuilt the following year in the form of a single-span 74-metre steel truss bridge.” [1: p32]
Limone to Vievola: Crossing the Col de Tende
The next length/tranche running South from Limone was 10.5 kilometres long and extended the line from Limone to Vievola(in the valley of the River Roya).
Looking into Limone Railway Station from the tunnel mouth South of the Station. A short two-span bridge
At the South end of the Limone Station site the railway bridged Piazza Risorgimento/Viale Valleggia at the East end of Piazza Risorgimento and the River San Giovanni (Valleggia Torrent) on two adjoining bridges. [Google Maps, July 2025]The two bridges carrying the railway over both the road and the river. [Google Streetview, August 2011]
Omitting mention of the section of the bridge over the road, Banaudo et al tell us that, leaving Limone Station, “the line crosses the San Giovanni valley … on a 13-metre masonry single-arch bridge, then enters the 423-metre-long Limone Tunnel which passes under the San Secondo hill. A 26 mm/m gradient leads to the tunnel under the ‘Colle do Tenda’ … where the gradient eases to 2 mm/m as far as the highest point on the line, 1040 [metres above sea level, in the tunnel]. From this point a 14mm/m gradient extends to the South portal of the tunnel … at 990 [metres above sea level]. At the Southern end of the tunnel, … a single-span 19.90 m steel truss bridge crosses the Roya River. … A short 25 mm/m slope then leads to Vievola Station.” [1: p34]
The railway is protected by two galleries at the South end of Limone Tunnel. The first effectively extends Limone Tunnel southwards. This is the South portal seen from a train approaching Limone Railway Station. [8]
Also seen from the South from the cab of the same train, this is the South portal of the Short second gallery. The gallery entrance to the tunnel above can be seen only a very short distance beyond this gallery to the North. [8]

This image shows the North Portal of the tunnel under the Col de Tende. It is taken from the cab of a train heading for Breil-sur-Roya in the late 20th century. [31]
Interestingly, the two tunnels on this length of the line are large enough to accommodate two tracks – this facilitates ventilation but also allows room for expansion should traffic levels later require it. [1: p34]
Another schematic drawing which this time shows the main locations on the line from Limone to Vievola. [17]
While all the previous construction tranches ended up in populated locations, Vievola was just a place name in the commune of Tende with a few farms and a chapel dedicated to the Visitation of the Madonna scattered in a small green area at the confluence of the Roya and the Dente rivers. Nowhere was available to house workers on the railway. So before works began at the southern end of the tunnel under the Col de Tende, the contractor had to construct a temporary village.
After initial surveys were completed late in 1889, tunneling under the Col de Tende began at both ends. Banaudo et al explain that the 8.1 kilometre tunnel passed through various different strata: “Jurassic, Triassic and Cretaceous limestone, Permian quartz, Liassic marly schists and Eocene sandstone. The work progressed normally until September 1893, when the works reached a dislocated gneiss bed interspersed with clayey layers made fluid by the infiltration of water from the Roya, whose bed passes three times above the axis of the tunnel. Soon, mud floods invaded the approach tunnel with each attempt to advance over the course of ten months. The working face advanced only a dozen meters, while some forty flows of various materials obstructed the tunnel, sometimes over a length of 40 metres, while the vault suffered as much as 1.7 metres subsidence in places.” [1: p32][33]
The works from the South were suspended in July 1894 about 1.6 km from the tunnel mouth. Attempts were made to divert ground water from the route of the tunnel with little success and a further collapse occurred in October 1894. [33]
Meanwhile, work progressed from the North until at about 2.7 km from the tunnel mouth ground water started entering the tunnel at a rate of 60,000 litres/minute. The bed of the River Royal above the tunnel began to collapse. The contractor admitted defeat and refused to continue work on the line. [1: p34][33]
After a few months delay and with the work now being undertaken by the state a renewed effort was made to take the work-faces forward. The solution was to bore the tunnel using compressed air drills inside a metal shield and with water being removed by a parallel collector channel. It took 470 days to progress the works beyond the difficult strata. Banaudo et al say that once work was 43 metres beyond the critical zone, the contract was handed back to the original contractor on 31st March 1896. The total delay was 34 months at a cost of 300,000 lire! [1: p34][33]
On 15th February 1898 at 1pm, the team working from the North end of the tunnel broke through the remaining rock to meet the team working from the South.Remaining contract works would mean that opening of the line between Limone and Vievola would not take place until 1st October 1900. [33][34: p116][1: p35]
When trains left the confines of the 8 kilometre tunnel their crews were probably grateful for the fresh air. I cannot imagine what it must have been like for the crews of steam engines on the line. Electrification could not come soon enough. “The tunnel was equipped with a two-wire contact line when the electrification of Cuneo Gesso – San Dalmazzo di Tenda line in three-phase alternating current 3.6 kV – 16⅔ Hz took place with electric traction starting from 15th May 1931.” [33][35: p171-172]
South of the tunnel, the railway crosses the River Roya before entering Vievola Railway Station.
This satellite image shows the line leaving the tunnel (at the very top of the image) and crossing La Roya (towards the bottom of the image). [Google Maps, July 2025]
It is not possible to see the tunnel mouth in this panoramic photograph taken from the E74 (D6204), nor is it possible to see the railway bridge over La Roya. The railway can be seen, as can the buildings close to the tunnel mouth on the East side of the line. The railway bridge over the river is behind the trees in blossom one a line from the camera to the red-roofed buildings. [Google Streetview, April 2008]As the E74 (D6204) descends along the valley of the Rya, the railway bridges it, adjacent to a road (off to the right of the picture) which serves Vievola Railway Station. [Google Streetview, October 2008]
The completion of the fifth contract still required the development of Vievola station. It was to be built on a large platform created using spoil from the tunnel works on a vast embankment formed from the tunnel spoil, with an underpass provided for the then SS20 (now E74/D6204) and shown above.
The approach to Vievola Railway Station from the South, as seen from the cab of a Northbound train. [8]
Banaudo et al tell us that, at the station, “The two platform tracks for passenger service were supplemented by two sidings and a dead-end track running alongside the goods shed and the military platform. At the western end of this section, a small wooden shed, an 8.50 m temporary turntable, a water tower, and two hydraulic cranes allowed locomotives to use this temporary terminus as they would at any terminus. In the same area, a wooden buffet building was built, which a shrewd manager, no doubt hoping to take advantage of the cosmopolitan movement of connecting passengers, dubbed a ‘restaurant’ in French.” [1: p40]
Vievola was a railway terminal for traffic to and from Piedmont and a hub for road connections onwards to Nice and Liguria. Banaudo et al point us to a magazine published in 1899, which mentions a trial of a steam-powered road vehicle which it was hoped would provide a service to Nice and the coast until such time as a railway was built. [1: p40][37] The service was a trial organised by the House of Ascenso et Cie, and ran from Vievola to Ventimiglia. The journey, lasted a total of six hours, including a 43-kilometre climb. The vehicles used were Scotte trains. The car wagon carries a 27-horsepower engine and seated 14 passengers; it also towed a second 24-seater wagon. [1: p40][38]
“Due to their slowness, the difficulties of driving cars on the narrow roads of the time and the damage caused to the cobbled and cylindered roads,” [1: p40] the ‘Trains Scotte’ were not a success, they probably did not circulate for more than a few months or weeks. ….
The next length of the line can be found here. [46]
RM 3201-3519 (FS 215)Locomotives
Banaudo et al tell us that throughout the 19th century and on into the 20th century passenger stock and freight wagons were unchanged. Improved 0-6-0 tender locomotives came available as they were delivered by the Breda and Mavag companies, these were more powerful and faster locomotives than the RM Nos. 3201 to 3519 (which became group 215.001 to 215.398 at the FS). They were given RM Nos. 3801-3868 (which became the FS 310 series).
Banaudo et al also comment that “genuine mountain locomotives made occasional appearances: these were 040s [ in UK annotation 0-8-0s] with a three-axle separate tender, series RM 4201 to 4487 (future series 420 FS), built from 1873 to 1905 based on an Austrian model by a dozen Italian, Belgian, German and Austro-Hungarian firms. These machines, reserved primarily for the main lines of the Alps and the Apennines, occasionally intervened on the Col de Tende line, during bridge tests for example. At this time, Cuneo still had no allocation of machines and those going up to Limone and Vievola were attached to the Torino depot and the Moretta shed, on the Cuneo Airasca line.” [1: p41]
An FS Class 420 locomotive. [41]
“In the early 1870s, the SFAI needed a locomotive suitable for heavy work on the most important mountain lines, such as the Giovi railway and the Turin-Modane railway, for which the 0-6-0 locomotives were becoming increasingly inadequate. The Ufficio d’Arte di Torino chose a 0-8-0 locomotive of the Wiener Neustädter Lokomotivfabrik (then known as “Sigl”), very similar to the Südbahn Class 35 a that it already produced.” [41][42: p190][43: p31]]
“The Class 420 was a typical long-boiler, inside-frame 0-8-0 locomotive of the era, that showed its Austrian derivation with its two-shutters smokebox door, and its outside Stephenson valve gear. The locomotives built before 1884 had the distinction of having curved foot plating over the wheels, while later units had straight foot plating and small splashers. Some of the locomotives were given a replacement boiler before 1914, but their performance remained mostly unchanged.” [41][43: p31]
“The first 60 locomotives were built by Sigl (from which they derived the nickname with which they were known for their whole career) for the SFAI. Production continued until 1890, from both foreign (such as Maffei) and Italian firms (such as Ansaldo and Breda), for a total of 189 locomotives; all these were divided in 1885 between the Rete Adriatica and the Rete Mediterranea. Building of further locomotives for the RM resumed in 1897, and continued until 1905, bringing the total of the Class to 293.” [41][42: p190-192]

Structures on the french side of the border would, when built, compete with the dimensions of the Rivoira Viaduct. The Eboulis Viaduct is 270 metres long and the bridge at Saorge is 60 metres high. However, the combination of these two dimensions (length and height) makes Rivoira Viaduct the most imposing on the line.

Industrialist Joanny Scotte, originally from Epernay in the Marne department, began his business in the mid-1880s producing steam-powered cars. From 1897, he offered road trains consisting of a tractor or a steam-powered car, pulling one or more trailers designed for the transport of passengers or goods. These vehicles travelled on roads using solid tyres. They never really went beyond the experimental stage due to their slowness, the difficulties of driving the vehicles on the narrow roads of the time and the damage caused to the cobbled and cylindered roads. [1: p40] Scotte road train services were reported in the last decade of the 19th century in the Île-de-France region (Fontainebleau, Pont-de-Neuilly, Courbevoie), in the Aube region (Arcis-sur-Aube – Brienne-le-Château), in the Manche region (Pont-l’Abbé-Picauville – Chef-du-Pont), in the Drôme region (Valence – Crest), and for military use. Scotte partnered with the Lyon-based car manufacturers Buire and Audibert-Lavirotte to produce some of its vehicles. [1: p41]
