Ruislip depot

Ruislip depot is a traction maintenance depot on the London Underground Central line, between the stations of Ruislip Gardens and West Ruislip in the London Borough of Hillingdon.

During the Second World War, anti-aircraft guns were made at Ruislip Depot.

Part of the depot was retrofitted with a green roof, as a trial for a larger-scale rollout across London Underground. The scheme was monitored by the University of East London.

Ruislip depot also has a single-track line that connects the Central line with the Metropolitan and Piccadilly lines when it is necessary to transfer trains between those lines.
