The Horton Light Railway had its origins in a contractor's line (the Ewell & Long Grove Railway) built in 1905 to transport building materials, coal and other supplies for London County Council's Epsom Cluster of psychiatric hospitals in the Horton area to the North-West of the town of Epsom.[1] The Light Railway Order did not permit the carriage of passengers. The railway connected with the mainline network just south of Ewell West railway station.
