It was opened by the Southern Railway on 6 July 1930 to serve new housing in Waddon, and Croydon Gas Works, and Croydon A & B Power Stations. An island platform accessed by a footbridge served two through tracks. Two other tracks at the station were sidings for the gas works and power stations. Services were westbound to Wimbledon through Mitcham Junction, and eastbound to West Croydon. Originally named Waddon Marsh Halt, the station was renamed Waddon Marsh on 5 May 1969. Nothing of the original station remains, the footpath that led to the station gives access to the Tramlink Stop.
