The Didcot Railway Centre is the Great Western Society's (GWS) working museum at Didcot, occupying the original GWR Didcot engine shed (81E) and adjacent yard. The Centre opened to the public in 1968, only three years after the closure of the BR steam shed, and has since grown into one of the most comprehensive single-company railway museums in Britain.

The collection focuses on the GWR and includes some of the most iconic engines associated with the company: 4073 Castle Class 4079 Pendennis Castle (returned from Australia in 2000), 6000 King Class 6023 King Edward II (rescued from Barry scrapyard and rebuilt to operating condition), the 4900 Hall Class, several 5700 Pannier tanks, an Iron Duke broad-gauge replica (built 1985 to 7 ft 0¼ in gauge), and the new-build 2999 Lady of Legend, a recreated Saint Class 4-6-0 completed in 2019.

The site features a unique broad-gauge demonstration line (rebuilt to original GWR 7 ft 0¼ in gauge) alongside the standard-gauge demonstration line, an extensive coal stage and turntable, the carriage shed with restored Royal Train and slip-coach examples, and a fully working signalling demonstration.

History

The Great Western Society was founded in 1961 by a group of schoolboys at Faringdon Road station, Berkshire, with the initial aim of preserving small GWR items. The Society moved to Didcot in 1967 after acquiring the closed BR engine shed, and opened to the public the following year.

Subsequent decades have seen the steady restoration of major engines, the building of the broad-gauge demonstration track and Iron Duke replica (1985), the return and restoration of Pendennis Castle from Australia (1994 onwards), and the new-build Lady of Legend Saint Class project (completed 2019).

Original line history

The Didcot engine shed was opened by the GWR in 1932 as a substantial four-road straight shed, replacing earlier facilities. It served the Western Region until BR steam ended in March 1965, after which the buildings remained largely intact until the GWS moved in.

Stations and infrastructure

The site features the original four-road engine shed (now the locomotive display hall), the coaling stage, turntable, water tower, the GWS signalling demonstration centre, two demonstration lines (standard and broad gauge), the carriage shed, and a small visitor centre. The site is integrated with Didcot Parkway Network Rail station.
