Buckinghamshire Railway Centre is a railway museum operated by the Quainton Railway Society Ltd. at Quainton Road railway station, in the far depths of "Metro-land", about 5 miles (8 km) west of Aylesbury in Buckinghamshire. The site is divided into two halves which are joined by two foot-bridges, one of which provides wheelchair access. Each side has a demonstration line with various workshop buildings as well as museum buildings.
Buckinghamshire Railway Centre is rail-connected because Quainton Road station is on the Network Rail freight-only line (formerly a mainline used jointly by the Great Central Railway and the Metropolitan Railway through the Metropolitan and Great Central Railways Joint Committee) which connects Aylesbury with the Bletchley to Oxford cross-country route at Claydon (LNE) Junction. This allows Chiltern Railways to operate occasional shuttle trains from Aylesbury to Quainton Road on Buckingham Railway Centre open days.
At the north-west corner of the site are the terminal buildings of 1851 from Oxford Rewley Road railway station transplanted here in 2002 to serve as reception, visitor centre and display building.
