The Llanfyllin Branch was featured in an article by Stanley Jenkins in the October 2003 issue of Steam Days magazine. [3]
The immediately adjacent Tanat Valley Light Railway is covered elsewhere on this blog. The articles about that line can be found here [4] and here. [5]
The two lines ran into the hills to the Southwest of Oswestry. The local Cambrian network is shown diagrammatically in the image below.

Trains on the branch ran from the Welsh border town of Oswestry to Llanfyllin in the Berwyn Mountains. The branch left the Oswestry & Newtown Railway at Llanymynech, where the station nameboard called on passengers for Llanfyllin and Lake Vyrnwy to disembark and change trains. The lake is a nearby beauty spot where there is a reservoir supplying water to Liverpool.
In July 1864, the Oswestry & Newtown Railway joined with other local concerns to form the Cambrian Railways Company with its headquarters at Oswestry.
Llanfyllin’s townfolk formed a company to secure a rail link to the Cambrian network. The Cambrian began to show some interest when ideas of an East-West mainline came to the fore.
A 10-mile branch was agreed from Llanfyllin to Llanymynech which, in the view of the companies which would soon form the Cambrian, would hinder any rival’s attempt to construct a mainline between the Midlands and the Welsh coast.
The modest scheme received Royal Assent on 17th May 1861 and the Act empowered the Oswestry & Newton Railway to build branch lines to Llanfyllin and Kerry. The Llanfyllin Branch was soon pegged out in advance of construction. It presented few engineering challenges as “for much of its length the proposed branch line would follow a comparatively easy course along convenient river valleys, and with few physical obstacles to impede [the] work.” [3: p627]
“The line was substantially complete by the early months of 1863, a significant event being the arrival of the locomotive Nant Clwyd at Llanfyllin in March of that year. The railway was opened on 10th April 1863 and branch trains began running through to Oswestry on 17th July 1863.” [3: p627]
The railway “was single track throughout, with intermediate stations at Llansantffraid and also Llanfechain. At Llanymynech the junction was situated to the North of the station, and this necessitated an awkward reversal when trains entered or left the branch. There were no tunnels on the branch, although several overbridges or underbridges were required including a 90-yard viaduct between Llanymynech and Llansantffraid. An additional stopping place was opened at Bryngwyn in the first few months of operation, although this new station was merely a request stop with no provision for goods traffic. The trains travelling eastwards to Oswestry were regarded as up workings, while westbound trains were down services.” [3: p627-628]
The new railway was soon functioning as a typical country branch line with a modest service of around five trains each way. “Minor changes took place at Llanymynech in 1866 in connection with the opening of the Potteries, Shrewsbury & North Wales Railway, but in the event this undertaking was more or less a total failure. Much later, in 1896, the Llanfyllin branch junction was re-aligned using part of the PS&NW route.” [3: p628]
“The Llanfyllin branch found a welcome, unexpected source of heavy freight traffic in the 1880s when Liverpool Corporation obtained powers for the construction of a massive dam at Llanwddyn, about seven miles to the west of Llanfyllin. By this means the surrounding valley was turned into a reservoir known as Lake Vrynwy from which water was supplied to Liverpool via a 75mile-long aqueduct. Materials needed in connection with this gigantic feat of Victorian engineering were delivered by rail to Llanfyllin, which became an important railhead while the reservoir scheme was under construction.” [3: p628]
In 1922, the Cambrian became an integral part of an enlarged GWR as part of the grouping required by the Railways Act of 1921.
Road competition led the GWR to become “a large-scale user of motorised road transport, with railway-owned lorries being employed for local cartage work in urban areas and as ‘country lorries’ for collection and delivery work in rural areas. Certain stations were selected as ‘country lorry centres’, while others were down-graded in various ways so that, by the later 1930s, many smaller stations were handling very little carted freight traffic. Oswestry and Llansantffraid, for example, both became ‘country lorry centres’, and a large rural area was then served by road transport, with GWR vehicles running on regular routes. In this way the railway could fight back against the road-transport operators.” [3: p628]
The GWR was also a pioneer in the use of motorised road passenger services. “By the post-Grouping period the GWR had introduced road feeder services on a very large scale, rural Wales being regarded as an ideal area for the employment of such vehicles. Oswestry emerged as an important centre in the company’s motor-bus network, with services radiating to towns such as Llangollen, Welshpool, and to Llanfair Caereinion. These extensive road services needed a relatively-large allocation of motor vehicles, among the buses working from Oswestry during the 1920s being Burford 30cwt buses Nos. 801, 807, and 861, and Thornycroft 30cwt vehicles Nos. 911 and 936. The GWR buses … worked in close conjunction with the trains as useful feeders for the railway system.” [3: p628] This was an early example of an integrated transport network!

To regularise its practice, the GWR obtained new legal powers “under the provisions of the Great Western (Road Transport) Act of 1928. This new legislation enabled the GWR to own, work, and use motor vehicles in its own right, and to enter into arrangements with other parties for the operation of road transport services. By virtue of these powers the railway company at once entered into detailed negotiations with certain road transport companies, and by 1933 all of the GWR motor-bus services had been handed over to ‘associated’ bus companies such as Crosville Motor Services Ltd.” [3: p629]
“This arrangement was supposed to lead to greater co-ordination between road and rail transport, but there is no doubt that in many areas the buses began to compete with the railways for what little transport was available in rural areas. The situation in respect of the Oswestry area seems to have been particularly disadvantageous as far as the GWR was concerned in that many buses ran on a Llanymynech-Oswestry-Gobowen axis in open competition with the rail service.” [3: p629]
“In some instances Crosville (or the other railway-associated bus companies) assisted the GWR by collecting and delivering parcels traffic, while goods traffic was handled by GWR motor lorries, some of which had been converted from former railway buses. Oswestry-based road motors Nos. 891, 897 and 861 … were adapted for use as lorries between 1926 and 1929. …They retained their old GWR fleet numbers. … Buses were more flexible than the railways, … to mitigate this the GWR opened numerous unstaffed halts. … One of these … was established in 1938 at Carreghofa in the Llanfyllin Branch, near Llanymynech.” [3: p629]
Jenkins tells us that the train services on the branch were similar throughout the years of its operation with five up passenger services to Llanymynech from Llanfyllin each weekday and five down trains. Occasionally these services worked through to Oswestry but, with the exception of the 1.43pm service, such movements were not always timetabled. The reverse workings, often unadvertised, ran from Gobowen through Oswestry and Llanymynech to Llanfyllin. Wednesdays and Saturdays, market days in Oswestry, were different, with two morning trains running through to Oswestry and two early afternoon trains back to Llanfyllin. There was no Sunday service. A daily branch goods train “generally departed from Llanymynech at 12.25pm and arrived at the terminus at 1.35pm, having called intermediately at Llansantffraid where half an hour was allowed for shunting operations. The return working left Llanfyllin at 2.30pm and, after spending another half an hour at Llansantffraid, … arrived at Llanymynech at 3.42pm.” [3: p629]
Jenkins comments that “the line was worked by short-wheelbase coaching stock for many years, although in GWR days 2-coach ‘B-sets’ and other formations were employed.” [3: p629]
The Cambrian Railway had very few small tank engines which meant that tender engines worked many of their small branch lines. Usually these would be ‘Queen’ class 0-6-0 locomotives. Following the grouping, GWR locos began to appear on the branch lines around Oswestry, particularly Armstrong and Collett 0-4-2Ts. Jenkins tells us that “these newcomers included ‘517’ 0-4-2T No 848 which worked on the branch at various times until its withdrawal in 1945, being out-stationed in the branch sub-shed at various times. The familiar Collett 0-4-2Ts were introduced by the GWR in 1932 as replacements for the veteran ‘517’ class 0-4-2Ts on local passenger services.” [3: p630]
The first examples of the non-auto ’58XX’ locomotives appeared on the branch in the 1930s. Jenkins notes that No. 5816 was sent to Llanfyllin shed as early as August 1933, while by 1947, the resident branch engine was No. 5806. The auto-fitted ’48XX’ class also arrived at Oswestry in the mid-1930s. These locos could also be seen on the Llanfyllin Branch. [3: p630] Dean goods 0-6-0 locos were also seen at times on the branch. Jenkins notes appearances of Nos. 2482 and 2535. No doubt the branch was served by a number of pannier tank (0-6-0PT) locomotives of different classes that were stabled at Oswestry. After nationalisation, by the mid-1950s, a group of Ivatt ‘2MT’ 2-6-0s were allocated to Oswestry and were employed on the branch. “As there was no turntable at the terminus the Ivatt Moguls generally ran tender-first towards Llanfyllin and then returned to Oswestry facing in the right direction. Several Llanfyllin branch services were at this time through trips to Gobowen which continued northwards over the Great Western branch to connect with the Shrewsbury & Chester main line. … At Gobowen it was found that the clearance between the stop block at the end of the down bay platform was insufficient for an Ivatt 2-6-0 running tender-first, and drivers were therefore instructed to enter the bay running chimney-first; this instruction probably explains why the engines normally faced northwards when they were running on the Llanfyllin route!” [3: p631]
The Route
We commence our journey at Oswestry Railway Station. We noted first that from 1860 onwards there were two separate stations in Oswestry – a GWR station and a Cambrian station.
The first 25″ OS map extract below shows the general arrangement of railway facilities in the centre of Oswestry at the turn of the 20th century. The second focusses on the two railway stations.



A series of photographs of the railway station can be found on the Disused Stations website. [32]

After the grouping in 1922 the GWR set about rationalising their inheritance. The old Cambrian station became the town’s passenger facilities and the GWR station was converted into the hub of an enlarged goods yard. “The Cambrian platforms were extended by 300ft, and a new branch bay was created on the west side of the station on a site that had previously been occupied by a large goods shed. At the same time the main up and down platforms were equipped with new canopies, and electric lighting was installed in place of gas in the goods yard and engine sheds. … Goods facilities were provided on a lavish scale, with sidings at both the north and south ends of the station. The main goods yard, which incorporated the original Great Western terminus, was situated to the north of the passenger station; the former terminus remained largely intact after its conversion to a goods depot, although part of the platform canopy was boxed-in to form a goods loading area.” [3: p632]
Goods facilities extended both to the North and South of the enlarged passenger station. Oswestry engine shed contained six terminal roads and sat to the North of the station complex, between the lines to Whitchurch and Gobowen. Jenkins tells us that a “standard GWR raised coaling plant was erected as part of the post-Grouping improvements, and this replaced an earlier Cambrian coaling stage. The Great Western coal stage was surmounted by a 45,000gallon water tank, while the old 45ft-diameter locomotive turntable was taken up and a new 65ft-diameter GWR one erected.” [3: p632]
The next two map extracts focus on these changes.



South of Oswestry, trains for Llanfyllin travelled along the GWR Whitchurch to Aberystwyth main line as far as Llanymynech, passing Llynclys junction where the Tanat Valley Light Railway diverged westwards on its way to Blodwell Junction and Llangynog. Llynclys Railway Station was situated a short distance beyond the junction. It “was a wayside station with a small but substantial station building on the up side and a waiting shelter on the down platform. In architectural terms the station building, with its two-storey stationmaster’s house and single-storey booking-office wing, was very typical of Oswestry & Newton practice. The nearby goods yard contained facilities for coal, livestock, and general merchandise traffic.” [3: p633]
The length of the line from Oswestry to Llanymynech is covered by the next sixteen extracts from the 25″ Ordnance Survey of 1900 and accompanying satellite images and photohgraphs.



The Cambrian Heritage Railway is extending and repairing track from Llynclys South northwards towards Oswestry to enable trains to run into the former Cambrian Railway headquarters at Oswestry. [17]







Weston Wharf Railway Station on the Cambrian Heritage Railways’ line to the South of Oswestry. “Plans to extend the line from Oswestry were reported in January 2016. The work was scheduled to proceed in three stages: phase one from Oswestry to Gasworks Bridge which carries the B4579 Shrewsbury Road over the line, phase two to make Gasworks Bridge passable and phase three to reach Weston Wharf. [24] At Gasworks Bridge, the track had to be lowered to allow trains to pass under the steel girder frame installed to strengthen the bridge. Funding was received from Shropshire Council and Oswestry Town Council.” [25][26][28]
“By April 2022 the 2 miles (3.2 km) of track from Oswestry to Western Wharf, which lay abandoned for more than 50 years, had been reinstated. The station was officially opened on 2 April 2022 by Helen Morgan MP and Vince Hunt, Chairman of Shropshire Council. It consists of a single platform, a run-around loop and a siding. Previously, there was no station here, only a goods depot.” [27][28]

The Tanat Valley Light Railway is covered by two articles which can be found here [18] and here. [19] The route of the main line and that of the Tanat Valley Light Railway are defined by the lines of trees in the 21st century. The village has extended across the railway line.


Llynclys South Railway Station is located just South of the original located Llynclys station, “on the other side of the B4396 road bridge. During the original commercial operation of the line, the site was used for goods handling. … The station was built as an alternative to the original Llynclys station, which has become a private house. Work on the South station began in 2004 and opened to the public in 2005. CHR currently keeps the bulk of its rolling stock here, on a number of sidings, and a new carriage shed is set to be built after having gained planning permission in 2007.” [23]

South of Llynclys trains ran on through Pant to Llanymynech which was nearly 6 miles South of Oswestry.














The location of the bridge in the map extract above is shrouded by the tree canopy. A modern satellite image would show very little as does the Streetview image below.







Llanymynech Railway Station was the point of departure for Llanfyllin Branch trains from the main line. In early year this required trains serving Llanymynech from Oswestry to undertake a reversal in order to travel along the branch. The same applied to trains from Llanfyllin needing to call at or terminate at Llanymynech.
This was addressed by providing a short chord line from the Llanfyllin Branch to what was once part of the Potteries, Shrewsbury and North Wales Railway (PS&NWR). “This remodelled layout enabled branch trains to serve Llanymynech station without reversing, although the new junction arrangements necessitated the abandonment of a small portion of the original Oswestry & Newton branch. … Further changes ensued in 1911 when a connection was established between the former PS&NW line and the Tanat Valley route at Blodwell Junction. This new line created a useful loop line between the Llanfyllin and Tanat Valley branches, although in the event the two-mile connecting line between Llanymynech and Blodwell Junction had a comparatively short life, and it was closed in the mid-1920s.” [3: p635]
Llanymynech grew as a Victorian village after the opening of the Montgomeryshire Canal in 1797. This length of Canal became part of the Shropshire Union Railways and Canal Company and then part of the LNWR. The Canal was only abandoned after the LNWR became part of the LMS. The Canal was not abandoned until towards the end of the Second World War (1944). Although Llanymynech has a Welsh name it sits on the English side of the border with Offa’s Dyke running through the parish. [3: p635]
The Oswestry & Newton Railway “constructed a simple two-platform station southeast of Llanymynech, plus an adjacent goods yard, to enable shipping of locally quarried limestone, and created products of quick lime and lead. However, under its Act of Parliament, it had agreed not to disturb the operations of the existing local tramways or canals, and hence access across each would either be over (bridge) or under (aqueduct). … The Hoffmann kilns were located on the opposite side of the canal to the chosen station site, and if accessed on the level would have required an aqueduct to be built under the canal. Not having the money to achieve this, the O&NR agreed to junction with the local tramways north of its station at “Rock Siding”. It hence built a bay platform on the northwest side of the station, from which line extended to the “Rock Siding”. To access the Hoffmann kilns, trains would firstly enter the bay, then reverse up the slope to the “Rock Siding”, where they would then change direction again by pulling forward over a bridge to the Hoffmann kilns.” [34]

Details and more photographs of Llanymynech Railway Station can be found on the Disused Stations website. [36]
Once the chord linking the old Llanfyllin Branch and the PS&NWR had been built and the chord between the main line and the PS&NWR was complete, trains from Oswestry and Llanymynech diverged West off the main line just South of Llanymynech Railway Station.
The Llanfyllin Branch
After running off the main line, trains for Llanfyllin passed under what would become the A483. The bridge appears on both of the last OS Map extracts above.

Carreghofa Halt was the first stop on the Branch, it was just a short distance from the mainline close to the chord which served to link the old branch and the PS&NWR line. It was an unstaffed stopping place, opened by the GWR on 11th April 1938, “its facilities comprised a short platform on the down side of the running line. The platform was of earth & cinder construction with revetting of old sleepers. A small wooden shelter was provided for the comfort of waiting travellers, while the simple platform was fenced with tubular metal railings. … Other features of minor interest at Carreghofa included a sleeper-built permanent-way hut to the east of the platform and an unusual overbridge immediately to the west of the halt. The bridge, which crossed the railway on a skewed alignment, was a single-span structure carrying the B4398 road and the Montgomeryshire Canal.” [3: p635]





Having passed beneath the road/canal bridge, “trains reached the junction between the Potteries, Shrewsbury & North Wales branch to Nantmawr and the short connection which gave access to the original Llanfyllin route. This 26-chain curve was opened on 27th January 1896 as a means of linking the PS&NW route to the original 1863 branch.” [3: p365][4][5]

Now heading pretty much due West the branch sets off for Llansantffraid. We will pick up this next length of the route in the second article in this short series.
