Tadworth railway station is in the county of Surrey. It is the penultimate station on the Tattenham Corner Line. Train services and the station are operated by Southern. Tattenham Corner actually lies to the north, so London-bound trains have to head south through Tadworth, before turning east through Kingswood and then north beyond there.
There are separate platforms for 'down' trains north to Tattenham Corner and 'up' trains to Purley and London, linked by a road overbridge at the south end of the station on which is located the former station building.
