Waterloo station itself is the original mainline station. Trains run to the south-west of England and are mostly operated by South West Trains
Waterloo tube station is a London Underground station. It is on the Bakerloo Line between Lambeth North and Embankment, the Jubilee Line between Westminster and Southwark, the Northern Line between Kennington and Embankment, and the Waterloo and City Line leading to Bank.
Waterloo East station is connected by a footbridge. This is a stop on the main line from Charing Cross station, connecting with London Bridge Station and serving destinations in south London, Surrey, Sussex and Kent. Platforms on Waterloo East are identified by letters rather than numbers, presumably to avoid confusion for staff working on both stations.
The station is linked to the London Eye by elevated walkways. Two matching footbridgess cross the River Thames either side of the rail bridge from Waterloo East to Charing Cross station. The two footbridges were rebuilt in 2002. The bridges are both called the Hungerford footbridge.
