Step on and Rise on up
Lots of escalators, the most in fact, and Abba loved it
London Waterloo - often called simply 'Waterloo' - opened on 11 July 1848, the name on opening was 'Waterloo Bridge Station', from the nearby Waterloo Bridge across the Thames. In 1886 it officially became 'Waterloo Station' reflecting the long-standing common usage, and that of some L&SWR timetables.
London Waterloo has 20 terminal platforms, making it the biggest station in the UK in terms of platform numbers. The station is managed by Network Rail while all trains are operated by South West Trains.
Waterloo is currently the second busiest station on the Underground network, after Kings Cross St Pancras, with the Bakerloo, Jubilee, Charing Cross branch of the Northern, and Waterloo & City lines all stopping.
And what would a very busy station need...escalators of course... in fact Waterloo Station has the most escalators on the London tube and station network: 23 plus two passenger conveyors.
Plus of course Abba sang about it!
