The Epsom and Leatherhead Railway was an independent line from the L&SW main line at Wimbledon through Epsom and Leatherhead towards Guildford. The LB&SCR entered into an agreement to share its station at Epsom and to use the line as far as Leatherhead. The line opened in August 1859 and in 1860 this portion was transferred to the joint ownership of the LB&SCR and the L&SWR. The LB&SCR then bought the Banstead and Epsom Downs Railway, which was building a branch line from Sutton to Epsom Downs for Epsom Downs Racecourse, opened in May 1865.
