The Tattenham Corner line is an 8 mi 14 ch (13.2 km) railway line in Surrey and Greater London, England. It runs from its western terminus at Tattenham Corner, near Epsom Downs Racecourse, to a junction with the Caterham line south of Purley. There are intermediate stations at Tadworth, Kingswood, Chipstead, Woodmansterne, Coulsdon Town and Reedham. All seven stations are managed by Southern, which operates all passenger trains. Most services run between Tattenham Corner and London Bridge via East Croydon.
The line was promoted in two parts by the Epsom Downs Extension Railway and the Chipstead Valley Railway companies. The first section, between Purley Junction and Kingswood, opened on 2 November 1897 as a single-track line. The South Eastern Railway (SER) operated all services from the outset. The SER took over the line in 1899 and was responsible for finishing its construction and the provision of double track. Tattenham Corner station finally opened on 4 June 1901, the day of the Epsom Derby. The Southern Railway electrified the line using the 750 V DC third-rail system in 1928.
