Doncaster Carr rail depot is a railway vehicle maintenance depot located alongside the East Coast Main Line in Doncaster, England.
The original facility Doncaster Locomotive depot was a major 12 road steam locomotive maintenance shed built by the Great Northern Railway in 1876. The shed remained in use under the successor companies London and North Eastern Railway and British Railways, being significantly modified in the mid 1950s; steam locomotive use at the shed ended in the 1960s.
In the latter part of the 20th century the facility was used for diesel locomotive maintenance. In the late 2000s the site was selected as a maintenance depot for trains procured under the Intercity Express Programme.
