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 spiral in this location consists of a number of tunnels and open lengths of track. The first tunnel encountered travelling South is the Scarassoui Tunnel (top-right) which has a gallery of a series of arches at its southern end. A length of open track leads to Peug Tunnel, Vernardo Tunnel, Caussagne Tunnel and then Berghe Tunnel. [31]

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. [51]

Significant savings on construction costs were made (even when the cost of construction of the bridge was included) by following the right bank of La Roya down towards Breil-sur-Roya. [1: p142]

The village of Saorge is a lovely ancient perched village sitting high above La Roya. We have stayed there three times over the years renting the same small apartment each time that we have been there. Most recently, we were there post-Covid and after Storm Alex. That short holiday was in November 2023.

The view from our apartment window – the railway can be seen on the far bank of La Roya, high up the valley side. The visible length of railway is that to the South of Four A Platre Tunnel. [My photograph 11th November 2014]

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 Railway between Nice, Tende and Cuneo – Part 3 – Vievola to St. Dalmas de Tende

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]

In the first two articles about the line from Cuneo to the sea we covered the length of the line from Cuneo to Vievola. These articles can be found here [9] and here. [10]

I also want to acknowledge the assistance given to me by David Sousa of the Rail Relaxation YouTube Channel https://www.youtube.com/@RailRelaxation/featured and https://www.railrelaxation.com and particularly his kind permission given to use still images from rail journeys that he has filmed on the Cuneo Ventimiglia railway line.

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]

Trains for Tende and beyond set off to the Southwest. The railway bridge can be seen at the bottom left of this image. [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.

A closer focus on the bridge spanning the River Dente. This image appears to be taken after the inundation which occurred with Storm Alex in 2020. [Google Maps, July 2025]

After crossing the 12 metre span bridge the line enters the 1273 metre long Branego horseshoe tunnel.

This photograph looks North from the mouth of the Branego Tunnel towards Vievola Railway Station. It is taken from the cab of the same North-bound train. [35]

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]

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]

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]

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]

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]

Leaving Tende Railway Station, the line soon passes onto the curved viaduct spanning the Roya River opposite the village. The viaduct has one 20-metre arch and eleven 15-metre arches.

Once across the viaduct, trains heading South ran on through three tunnels on the left bank of La Roya on a falling grade of 25mm/m. These were:

A short distance further South the railway bridges a minor road. These are the bridge parapets seen from the cab of a South-bound train. The minor road is just visible to the left of the image. [55]

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]

Leaving La Brigue Railway Station the line resumes following a falling grade of 25 mm/m. This continues through the Levenza viaduct, which, as we have seen consists of three 8-metre arches abutting a single span road bridge. Beyond this is the Levenza tunnel (418 m long). …

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]

Trains are within the tunnel for some minutes as they cover nearly two kilometres of turning track within the tunnel. This view comes from the cab of a South-bound train. [55]

The Rioro Spiral Tunnel opens onto the left bank of the Levenza River, just before its confluence with the Roya River.

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]

The photograph was taken on the hillside to the North of the village. This image was shared on the Ferrovia internazionale Cuneo-Ventimiglia-Nizza Facebook Group by Luisa Grosso on 1st November 2021.

The locomotive Depot at St. Dalmas de Tende. The depot was on the Southeast side of the running lines opposite the railway Station and close to the Biogna River. The road shown on the OpenStreetMap plan of the modern station to the Southeast of the site is the road shown at the top of this plan. This drawing comes from From the December 1929 Technical Magazine of Italiane Ferrovie. It was shared on the Ferrovia Internazionale Cuneo-Ventimiglia-Nizza Facebook Group on 13th February 2024 by Francesco Ciarlini Koerner. [4]

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]
