Selsdon railway station was on the Croydon, Oxted and East Grinstead Railway and the now-closed Woodside and South Croydon Railway. Opened in 1885 as "Selsdon Road", it was two miles from Selsdon village. The name was changed with effect from 30 September 1935 in an attempt to attract more passengers to the line - users of the railway preferring to use nearby South Croydon, which had a higher frequency of service.

Selsdon saw its last passenger train on 13 May 1983, with the Woodside and South Croydon line officially closing three days later. At closure Selsdon was the last gas-lit station in London.
