Didcot Railway Centre is a former Great Western Railway engine-shed and locomotive stabling point located in Didcot, Berkshire, which today has been converted into a comprehensive railway museum and preservation engineering site.


The founders and commercial backers of the GWR supported Isambard Kingdom Brunel's scheme to develop an integrated railway and steam-ship service which allowed trans-Atlantic passengers and freight quicker passage to and from London to New York. However, whilst backing the scheme the railway had to make a profit, and so it took a number of detours and added both mainline and branch line traffic to increase its domestic earnings. This earned the railway the nickname The Great Way Round from its detractors.[1]

Whilst the route from London Paddington to Reading was relatively straight, the then obvious most direct route to Bristol would have taken the railway further south, thus avoiding both Didcot and Swindon. However, passenger and freight traffic both to and from Oxford and onwards to the Midlands in part dictated a more northerly route. Secondly Brunel had originally planned to cut through Savernake Forest near Marlborough to Bristol, but the Marquess of Ailesbury, who owned the land, objected - having previously objected to part of the Kennet and Avon Canal running through his estate. With the railway needing to run near to a canal at its midpoint - as it was cheaper to transport coal for trains along canals at this time - and with need for the branch northwards to Cheltenham by way of Stroud, Swindon was the next logical choice for the junction (and later railway works), 20 miles north of the original route. This dictated that the Oxford junction also be moved northwards, and hence via Didcot.[1]


Didcot Railway Centre, Oct 2001

Due to the technical operational difficulties of running and maining a mainline service from London to Bristol, as well as the need for servicing locomotives going to Oxford, Didcot became an obvious midpoint maintenance and stabling point. Having built a timber-framed broad gauge shed on the original site during the railways development west in the 1800s, in June 1932 a new steel-framed half-brick 4-road through shed (210 x 67 feet), was completed by the GWR under the Loans and Guarantees Act (1929). With shed code DID, it also included a repair shop (84 x 42 feet), coaling stage (43 x 36 feet), sand furnace (10 x 10 feet) and 65-foot turntable plus associated offices (210 x 15 feet).[1] During the Second World War, a standard steel-framed with corrugated tin-panel covered ash shelter was erected.[1]


After the War, the site remained virtually unchanged during the nationalised ownership of British Railways, but for taking on the new code of 81E. The standard allocation of locomotives remained the same, with Halls, Dukedogs and Panniers making up the bulk of the depot's fleet.[1]


With the replacement of steam with diesel-traction under the Beeching Axe, the shed was closed in June 1965.[1]

Formation and site lease

The Great Western Society was offered the use of the former Didcot locomotive depot, taking it over in 1967. In the 1970s, the Society negotiated a long-term lease with British Rail which was to expire in 2019. But this was subject to a six-month termination clause which could force the Society to quit the site, and which could operated at any point in time by freeholder (now Network Rail).

In an attempt to secure a long-term future for the society, in 2002 the Great Western Society opened negotiations with Network Rail either to purchase the site or to extend the lease. In May 2007, Network Rail said they were prepared to sell the site subject to regulatory approval but thought the site might be needed again for the mainline railway, on the rebuilding of Reading station or as a Crossrail project depot, or for the Intercity Express Programme. Eventually, after much lobbying and the involvement of the local MP, the Chairman of the Great Western Society signed a new 50-year lease with Network Rail, preserving the site for at least another 50 years.

Museum and railway centre

A reconstruction of Brunel's atmospheric railway

Today the GWS have developed the site, which still retains many of the original GWR buildings and features, as both a working steam locomotive and railway museum, engineering maintenance centre, and railway line offering short rides to visitors.

Access via Didcot Parkway station brings the visitor into the southern end of the site, at the start of the ramp coal wagons would take up to the coaling stage. Beyond this is the original 1932 four-road engine shed, and beyond this the original repair shed and 1988 constructed locomotive works, both of which have restricted access due to safety concerns. Beyond this lies a Ransomes & Rapier 70-foot turntable and pit, originally built for the Southern Railway and istalled at Southampton Docks.

The centre regularly holds events such as steam and diesel railcar days. Members of the Great Western Society are active in the preservation of locomotives and rolling stock. Certain 'new-build' projects to create locomotives that did not escape wholesale scrapping are also undertaken at Didcot, such as the completed Firefly locomotive, a 'Saint' class (using a 'Hall' class chassis and boiler) and a 'County' class locomotive (using a 'Hall' class chassis and an LMS '8F' class boiler).

Running lines

There are three short lengths of running track, each with a station at both ends:

  • Branchline: starts at a typical GWR wayside halt, named Didcot Halt, and runs north on the western edge of the site towards the transshipment shed. Dating from broad gauge days, it was used for transferring goods from broad to "narrow" (which is to say standard) gauge rolling stock and vice-versa. It was moved to its present location carefully from its nearby original site.
  • Broadgauge Line: the broadgauge line of 7 feet starts from the transshipment shed, and runs halfway back down the branchline. The 2005 replica GWR Firefly is housed within the shed when not running
  • Mainline: starts opposite the site entrance, using a pre-fabricated concrete station platform from Eynsham, and runs on the eastern-edge of the site to a newly built platform at the other. Long-term plans include the reconstruction of the Brunel-designed building from Heyford station on this platform.


The railway centre is entirely surrounded by active railway lines and has no road connection of any kind. Public access is on foot from a subway at Didcot Parkway railway station, which links the centre by rail to London and much of the southern and Midland counties.
