London Underground

The London Underground is an electric railway public transport network (a metro or subway system) that runs both above and below ground throughout the Greater London area. It is usually referred to by Londoners as either simply "the Underground" , or (more familiarly, due to the shape of its deep-bore tunnels) as "the Tube". It is the oldest and biggest such underground system in the world. Operations began on 10 January 1863 on the Metropolitan Railway; most of the initial route is now part of the Hammersmith & City Line.
