West Ruislip tube station
The Central line's Ruislip depot is east of West Ruislip station, and has a connection via a shunting neck to the Network Rail westbound track west of the station to allow rolling stock and material deliveries. The depot also has a connection to the Uxbridge branch tracks of the Metropolitan and Piccadilly Lines which pass under the Central line east of West Ruislip; it is used only for empty stock movements and works train access. Two sidings west of the station to the north of the running lines provide layover facilities for works trains.
