Finchley Central is a London Underground station in the Church End area of Finchley, north London. The station is located on the High Barnet branch of the Northern line, between West Finchley and East Finchley stations; it is the junction for the short branch to Mill Hill East. The station is around 7 miles north-northwest of Charing Cross and is in Travelcard Zone 4. The station was opened on 22 August 1867 as part of the Great Northern Railway's line between Finsbury Park and Edgware stations. As part of London Underground's Northern Heights plan, Northern line trains started serving the station in 1940 and main line passenger services ended in 1941. History Original station Finchley Central station was built by the Edgware, Highgate and London Railway (EH&LR) on its line from Finsbury Park to Edgware. As construction of the line was nearing completion and before it opened it was purchased in July 1867 by the larger Great Northern Railway (GNR), whose main line from King's Cross ran through Finsbury Park on its way to Potters Bar and the north. The station, originally named Finchley and Hendon, opened along with the railway to Edgware on 22 August 1867 in what was then rural Middlesex. It was north-northwest of Charing Cross as the crow flies, and from the GNR terminus at King's Cross. A branch line from Finchley Central to High Barnet was constructed by the GNR and opened on 1 April 1872. After the 1921 Railways Act created the Big Four railway companies, the GNR became part of the London & North Eastern Railway (LNER) in 1923. The station was renamed by the GNR twice: to Finchley on 1 February 1872 and Finchley (Church End) on 1 February 1894. It was given its current name on 1 April 1940. At the start of the 1930s the station had around 54 trains daily from High Barnet running to Finsbury Park and then either King's Cross, Moorgate or Broad Street. Trains between Finchley Central and Edgware typically operated as a shuttle, although some trains ran through to the terminals. Northern Heights plan In 1935, the London Passenger Transport Board (LPTB) announced a proposal, which became known as the Northern Heights plan, to take over the LNER lines from Finsbury Park to Edgware, High Barnet and Alexandra Palace, and link them to the Northern line with new tunnels from the Northern line's terminus at
