Southall was the home of Southall Studios, one of the earliest British film studios. It played a historic role in film-making from its creation in 1924 to its closure in 1959. There has been a locomotive works at the Southall Depot for nearly 150 years. Originally a Great Western Railway shed, it was possibly the last London steam depot, outlasting Old Oak Common and Stewarts Lane depots. The depot was later used for DMU maintenance and as a base for the electrification programme. Currently the site, now referred to as the Southall Railway Centre, is used by three independent groups, including Locomotive Services (where volunteers can contribute to the preservation and restoration of mainline locomotives) and the Great Western Railway Preservation Group.
