Located opposite and accessible from Dunstall Park railway station, the shed backed onto the Stafford Road, with the throat facing Wolverhampton Low Level.

[2] The decision was taken to build a new GWR standard-pattern two-turntable with northernlight roof shed, 0.25 miles (0.40 km) toward Wolverhampton Low Level, which opened on 1 July 1907 under the code OXY.

Provision was however made for two further turntables should the need arise, and so the standard pattern twin-ramp coaling stage was offset to allow for future development.

After Pendolinos were chosen as the preferred new rolling stock by the former InterCity West Coast Franchise holder Virgin Trains, Alstom needed maintenance facilities.

Lighter maintenance, cleaning and overnight stabling is carried out at Alstom's other centres: Wembley (London); Edge Hill (Liverpool); Polmadie (Glasgow); and Oxley, which were redeveloped for their purposes.
