Old Oak Common TMD is a Traction Maintenance Depot to the west of London, in Old Oak Common. The depot is the main facility for the storage and servicing of locomotives and multiple-units from Paddington Station. The depot codes are OC for the diesel depot and OO for the carriage shed. In steam days the shed code was 81A.

The area is also where two GWR main lines divide: the 1838 route to Reading via Slough, and the 1906 New North Main Line via Greenford to Northolt Junction, the start of the Great Western and Great Central Joint Railway line. The former is in use for regular passenger services; the latter is used overwhelmingly by freight trains and empty coaching stock movements.

Following the reconstruction of Paddington Station and the introduction of larger locomotives and new routes, the Great Western Railway required a larger depot than that at the 1855 constructed Westbourne Park, at which to service its locomotives and carriages.

In 1901, a site was acquired in South Acton, south of the Grand Union Canal and on the upside of the mainline. Taking four years to layout and build, designed by G.J. Churchward, it was the largest depot on the entire GWR system, and set the pattern for similar depots throughout the GWR including Tyseley.
