London Waterloo is a major railway station and transport interchange complex in London, England. It is located in the London Borough of Lambeth, near to the South Bank. The complex comprises four linked railway stations and a bus station. The whole complex is within Travelcard Zone 1. The adjoining Waterloo International station is the current London terminus of Eurostar Channel Tunnel passenger trains. Waterloo East and Waterloo Tube Station also adjoin.
According to the station usage figures for 2004-2005 and 2005-2006, London Waterloo is the busiest station in the UK (in terms of passenger numbers). This is thought to be due to the Eurostar connections and is likely to drop in 2007 when High Speed 1 is fully open.

Waterloo mainline station
Waterloo International station adjoins Waterloo mainline station and has its own two-level concourse and train shed. It is the current London terminus for Eurostar trains to Belgium and France. The station is managed by Eurostar.
It was built in the early 1990s at a cost of £130 million

Waterloo station and the Waterloo Underground station are the setting for the Kinks song "Waterloo Sunset", written by Ray Davies and recorded in 1967. Its lyrics describe two people meeting at Waterloo Station and crossing over the river (via Waterloo Bridge, as Davies has confirmed). The song has been recorded by Cathy Dennis and Def Leppard, whilst other acts (like David Bowie and Elliott Smith) have covered the song in live performances.
The station is also the subject of John Schlesinger's documentary film Terminus.
The Bourne Ultimatum, staring Matt Damon, was filmed at Waterloo Station during mid-April 2007
The lyrics in the 1979 song "Rendezvous 6:02" by British progressive band U.K. describe a meeting at Waterloo Station.
The lyrics to "Torn On The Platform" by Jack Penate refer to the station ("train leaves at two, platform 3, Waterloo").
