A Long Way Down
Angel Station - the longest escalator in Western Europe
The London Underground is the 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 - the latter deriving from the shape of the system's deep-bore tunnels - although about 55% of the network is above ground.
And here's the thing... it also has the longest escalator in Western Europe at 197 feet (60m) long.
And the winning tube station - 'Angel station' on the Northern line.
