Epsom Downs railway station is a railway station located on the boundary of the Reigate and Banstead and Epsom and Ewell boroughs of Surrey, with the railway to the north forming a continuation of the boundary. The station, and all trains serving it, are operated by Southern, although a terminus of its own branch line is grouped as part of the Sutton & Mole Valley Lines. In the past the station had nine platforms, but today only one is in use. Epsom Downs is also served by nearby Tattenham Corner station, which is on the Tattenham Corner Line, also served by Southern.
