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.
