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