Liverpool Street station is a central London railway terminus and connected London Underground station in the north-eastern corner of the City of London. It is one of the busiest railway stations in London, serving as the terminus of: the West Anglia Main Line to Cambridge; the busier Great Eastern Main Line to Norwich, local and regional commuter trains serving east London and destinations in the East of England; and the Stansted Express service to Stansted Airport. The station opened in 1874, as a replacement for Bishopsgate station as the Great Eastern Railway’s main London terminus. By 1895, it had the largest number of platforms of any terminal railway station in London. During the First World War, an air raid on the station in 1917 led to 162 deaths. In the build-up to the Second World War, the station served as the entry point for thousands of child refugees arriving in London as part of the Kindertransport rescue mission.
