(Brighton Main Line)
However the station was renamed again to Balham & Upper Tooting in 1927 before finally being changed back to Balham again in 1969. The station was electrified as part of the LB&SCR's 6600v AC overhead line "Elevated Electric" system in 1911  though due to interruption caused by the First World War all of the lines through the station were not completed until 1925. However in the same year Southern Railway, who now operated the LB&SCR lines decided to standardise on DC third rail, Balham was converted in 1929.
Balham is built on an embankment with access between the platforms via an underpass. Although there are four platforms only two are usually used. The station is managed by Southern who operate all services though the station to destinations including London Victoria, London Bridge, Epsom, Sutton and Milton Keynes Central.
