The rolling stock preserved on the West Somerset Railway is used to operate trains on the West Somerset Railway (WSR), a heritage railway in Somerset, England. There is a variety of preserved steam and diesel locomotives and diesel multiple units, passenger coaches and goods wagons. Most of these are typical of Great Western Railway (GWR) branch lines in Somerset, or of the Somerset and Dorset Joint Railway (SDJR). Some are owned by the railway itself but most are owned by various individuals or voluntary groups such as the West Somerset Railway Association (WSRA), Diesel and Electric Preservation Group (DEPG), and Somerset and Dorset Railway Trust (SDRT).

The line is also regularly visited by locomotives based elsewhere. Some come for a day on a railtour, others for a few days or weeks to take part in a special gala, but a few stay for many months and form part of the stock working scheduled trains. Over the years these have included well known locomotives such as City of Truro, Taw Valley, Duke of Gloucester, Evening Star, Royal Scot, Tornado, Bittern, Britannia, Sir Lamiel and King Edward I.

Maintenance facilities

The old goods shed at has been converted to an engine shed for inspections and running repairs to the operational locomotives. A secure compound at is the base for locomotives working from that end of the line. Most diesel locomotives work from the DEPG depot at . The permanent way department is based at and maintain their wagons in the old goods shed there.

Restoration and heavy repairs are undertaken at several locations, including workshops attached to the engine sheds at Minehead and Williton. There is also another shed at Williton used for steam locomotive restoration and vintage coaches, the operating coaches are maintained in a modern shed at Minehead, and the SDRT have workshops at their museum at .

Steam locomotives The following locomotives are currently based on the West Somerset Railway but may sometimes be away from the line.

ImageClassWheelsNumber & nameBuiltNotesGWR 450045611924The 'small prairie' locomotives were designed for lighter duties on often lengthy branch lines. The 4500 Class were introduced in 1906. 4561 was built in 1924, working initially in the Birmingham area for three years before moving southwards, settling in from 1938. Twenty years later it moved to from where it regularly worked the Kingsbridge branch line. In 1962 it was sold for scrap to the Woodham Brothers. It was purchased by the WSRA in 1975 and was placed in service in 1989. It was taken out of service in 1998 when its boiler certificate expired and is now undergoing a full overhaul.GWR 4575554219281975The 4575 class, similar to the 4500 Class represented by here 4561, but with a larger water tank and other improvements. 5542 was turned out from Swindon in 1928 and sent to but it then moved southwards and even spent a time based at Taunton. Withdrawn in 1961, the following year it too was sold to the Woodham Brothers and spent 13 years at Barry before being brought by the WSRA. Restoration took until 2002 and it is now in service in GWR unlined green livery. As it is a little underpowered for the heavy trains that now run on the railway it often spends long periods working on other railways.BR Standard Class 4 2-6-4T8006419532023Allocated to both the London Midland and Southern Regions during its lifetime, the locomotive was withdrawn from BR service at Bristol Barrow Road in September 1965. After being purchased from Barry scrapyard in 1973 by the 80064 Locomotive Fund, it was initially restored at the South Devon Railway in 1981, before being moved to the Bluebell Railway in 1984. The owning group donated the locomotive to the WSRA in 2023 and the locomotive was subsequently moved to the railway. The locomotive's boiler is being overhauled by Riley & Son in Lancashire, whilst the chassis was moved to Cranmore on the East Somerset Railway for overhaul in April 2026, where the locomotive is hoped to return to steam in the summer of 2028 after a period of running in.GWR 51015199193420215199 spent most of its service career on GWR's Birmingham suburban lines, working local passenger trains. It was retired in 1963 when steam services were taken over by railcars, and remained in storage at Barry Scrapyard for 22 years. Its first home in preservation was the Gloucestershire Warwickshire Railway, where restoration was originally started, but it moved to Long Marston MoD and later Llangollen for the completion of its overhaul, finally returning to steam in 2003. It initially came to the West Somerset Railway for the 2021 season.GWR 6400643519372024Another 'pannier tank' engine, this class was fitted with equipment for working Auto trains. 6435 was withdrawn on 12 October 1964 and entered preservation with the Dart Valley Railway on 17 October 1965. It was transferred to the Torbay Steam Railway but was then moved to the Bodmin and Wenford Railway before being sold to the West Somerset Railway in 2024.GWR 78007821 Ditcheat Manor1950The 'Manor' Class was designed by Charles Collett as a large lightweight locomotive for long but lightly constructed routes, mainly in west Wales and south west England. Construction of the first 20 started at Swindon in 1938, followed by another 10 in 1950 for British Railways. 7821 Ditcheat Manor is now the property of the WSRA. It was moved in 2010 to Swindon's Steam Museum where it was displayed for eight years. In August 2018 it moved to the nearby Swindon Designer Outlet for display. GWR 78007822 Foxcote Manor19502018Designed with a lighter axle loading than the red-rating of the other GWR mixed traffic Hall and Grange 4-6-0 classes, the Manor class were ideally suited to the lightweight cross country and coastal routes of the former Cambrian Railways. 7822 was always based on the former Cambrian Railways. Its first allocation was to Oswestry depot. Withdrawn in 1965 from Shrewsbury, it was towed to Woodham Brothers scrapyard in Barry, South Wales. It was saved from there in 1974, when it was moved to Oswestry, the then headquarters of the Cambrian Railways Society. In 1978 it was moved to the Llangollen Railway where it returned to service in 1988.7828 Odney Manor19502004Initially based at Shrewsbury shed, it moved to Croes Newydd in 1961, in 1963 for a short while, then returned to Shrewsbury, from where it was withdrawn in 1965, moving to Barry scrapyard in 1966. It was rescued privately in 1981 and moved to the Gloucestershire Warwickshire Railway where restoration was completed by 1987. It worked on the Gwilli Railway, Llangollen Railway, and East Lancashire Railway, before coming to the WSR in 1995. Its owners sold it to the WSR in 2004. On 17 June 2011 it was temporarily renamed Norton Manor (the name intended for cancelled locomotive 7830) after 40 Commando's base alongside the railway at Norton Fitzwarren. It has been repainted in the BR lined green livery that it carried in 1957.GWR 93519351Great Western locomotives were assembled in different configurations from a range of standardised components. The basic parts of the 'large prairie' 2-6-2Ts were considered at different times as being the possible basis of a small 2-6-0 'Mogul', but this was never followed through. 5193 was purchased for preservation in 1979 and moved from Barry Island to Steamport Southport where restoration to running order was planned, but prevented by lack of funding. 5193 was purchased by the West Somerset Railway in 1998 and moved to Minehead where restoration to running order was to be undertaken. Because of the degree of work needed to restore it as a tank locomotive, and because a small tender locomotive was thought to be more useful on the lengthy railway, it was decided in 2000 to convert it to the mooted 2-6-0 design. Work was completed in 2004 when it appeared in plain GWR green livery.946619522019 Formerly based at the Buckinghamshire Railway Centre the locomotive was subsequently sold to JJP Holdings South West Ltd and was based at the West Somerset Railway after a short return visit to the Mid-Norfolk Railway. It was resident at the Ecclesbourne Valley Railway but moved back to the West Somerset Railway in early 2022 where it will operate until its boiler certificate expires in 2025.
