Southfields is a London Underground station in Southfields in the London Borough of Wandsworth. The station is on the District line between and stations. The station is located on Wimbledon Park Road at the junction with Augustus Road and Replingham Road. It is in Travelcard Zone 3. Southfields is the most convenient station from which to reach the All England Lawn Tennis and Croquet Club, venue of the Wimbledon Tennis Championships; station is slightly closer as the crow flies but requires a longer walk. During the tournament, more than three times the usual numbers of passengers pass through the station. History The station was opened by the District Railway (DR, now the District line) on 3 June 1889 on an extension from Putney Bridge station to . The extension was built by the London and South Western Railway (L&SWR) which, starting on 1 July 1889, ran its own trains over the line from a connection at East Putney to its to line. The section of the District line from Putney Bridge to Wimbledon was the last part of the line to be converted from steam operation to electric. Electric trains began running on 27 August 1905. Main line services through Southfields were ended by the Southern Railway (successor to the L&SWR) on 4 May 1941, although the line remained in British Rail ownership until 1 April 1994 when it was transferred to London Underground. Until the transfer, the station was branded as a British Rail station. The route from Wimbledon to Wandsworth Town (Point Pleasant Junction) is still used by South Western Railway for empty stock movements and occasional service train diversions, as well as three daily SWR services which run to and from Waterloo via the route in the early hours of the morning without stopping at Southfields. There are very infrequent movements of Network Rail engineering trains and light engine movements through the station as well. It was once planned that the potential Chelsea–Hackney line would call at Southfields, by supplementing or replacing the existing District line service. These plans have since been superseded by the planned Crossrail 2 line, which would serve Wimbledon. Station upgrade The station was upgraded in the early 2010s, with a new lift providing step free access. This work was done in preparation for the 2012 Olympic Games, when the Olympic Tennis Tournament was held at the All England Club. The upgrade will
