From Wikipedia : Banstead railway station serves the village of Banstead in the borough of Reigate and Banstead in Surrey. Its wider definition of Banstead Village and Nork wards is relevant here as both are equally well served by it as it lies narrowly in the latter. The station, and all trains serving it, are operated by Southern. It is on the Epsom Downs branch line, which is served as part of Southern's Sutton & Mole Valley Line services. It is between Belmont and Epsom Downs, 17 miles 40 chains (17.50 miles, 28.16 km) down the line from London Bridge, measured via West Croydon.
