Holborn tube station

Holborn (/ˈhoʊbərn/ HOH-bə(r)n) is a London Underground station in Holborn, Central London, located at the junction of High Holborn and Kingsway. It is served by the Central and Piccadilly lines, and is in Travelcard Zone 1. On the Central line the station is between Tottenham Court Road and Chancery Lane stations, and on the Piccadilly line it is between Covent Garden and Russell Square stations. Close by are the British Museum, Lincoln's Inn Fields, Red Lion Square, Bloomsbury Square, London School of Economics and Sir John Soane's Museum.

Located at the junction of two earlier tube railway schemes, the station was opened in 1906 by the Great Northern, Piccadilly and Brompton Railway (GNP&BR). The station entrances and below ground circulation were largely reconstructed for the introduction of escalators and the opening of Central line platforms in 1933, making the station the only interchange between the lines. Before 1994, Holborn was the northern terminus of the short and little-frequented Piccadilly line branch to Aldwych and two platforms originally used for this service are disused. One of the disused platforms has been used for location filming when a London Underground station platform is needed.

While the two disused platforms are now closed to the public, they can be still be seen on a "Hidden London" guided tour held by London Transport Museum.
