Diesel locomotives had been stationed at the old steam shed at Grimesthorpe until the new facilities were completed and the locomotives were moved to their new home. The site also included a small electric locomotive servicing shed at the south end of the Secondary Yard, replacing the facilities at Darnall. Diesel railcars, which had been serviced at Darnall, were moved to a new servicing depot adjacent to the "Fish Dock" at the south end of Sheffield Midland station.
In 1995, as a part of the reorganisation for privatisation, RFD was required to relinquish some of its Class 47s to Freightliner. The following year, EWS bought RFD, mostly for the lucrative Channel Tunnel operations.
Since the Class 47s were considered life expired by EWS management, and there were other depot facilities relatively close by (Toton, Bescot and Doncaster), and the other RFD locomotives were all electrics based at Crewe Electric TMD, the need for the Sheffield depot was deemed unnecessary.
