The London Underground is a metro system serving a large part of Greater London and neighbouring areas of Essex, Hertfordshire and Buckinghamshire in the UK. It is both the world's oldest underground railway and the oldest rapid transit system.
It was also the first underground railway to operate electric trains.
It is usually referred to as the Underground or the Tube (deriving from the shape of the system's tube like tunnels) although more than half of the network is above ground.
