This article contains notable statistics about the London Underground.
Distances * The longest distance between two stations is 6.26 km (3.89 miles), between Chalfont & Latimer and Chesham on the Metropolitan line. The longest distance between two underground stations is between Caledonian Road and on the Piccadilly line. * The shortest distance between two stations is between Charing Cross and Embankment, a distance of 100m (109 yards), which is stated on many tube maps.
Locations * The station furthest south is Morden on the Northern Line. The station furthest north is Chesham on the Metropolitan Line. * Using Charing Cross as the marker, Chesham has been the furthest station from Central London since 1994, prior to which it was the now closed Ongar station. * The furthest station from Central London ever regularly served by a London Underground service was Verney Junction which was at the (then) far end of what is now the Metropolitan Line. Located in a hamlet in rural Buckinghamshire it is over 64km (40 miles) from Charing Cross.
Elevations * Hampstead is the deepest station under the surface at 58.5 metres (64.0 yards, 192 feet). However, it is not the deepest below sea level as the station's surface building is near the top of a hill. * The deepest platforms below sea level are the Jubilee Line platforms at Westminster which are -32 metres (-35 yards). * The highest point above ground on the Underground is the viaduct over Dollis Road between Finchley Central and Mill Hill East on the Northern Line. It is 18 metres (60 feet) above the ground.
