Liverpool Street station

Liverpool Street station, also known as London Liverpool Street, is a central London railway terminus and connected London Underground station in the north-eastern corner of the City of London, in the ward of Bishopsgate. 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 on 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. The station was damaged by the 1993 Bishopsgate bombing, and during the 7 July 2005 bombing seven passengers were killed when a bomb exploded aboard an Underground train just after it had departed from Liverpool Street.

Liverpool Street was built as a dual-level station with provision for the Underground. A tube station opened in 1875 for the Metropolitan Railway, and the station today is served by the Central, Circle, Hammersmith & City and Metropolitan lines, and is in fare zone 1.

Services
Liverpool Street is the third-busiest railway station in the United Kingdom after Waterloo and Victoria, both also in London. It served over 63.6 million passenger entries and exits in 2014–15 and is a popular destination for commuters; a report in 2015 ranked the route into Liverpool Street as the eighth busiest in London, running around 3.9% over capacity. It is managed directly by Network Rail.

Trains depart from Liverpool Street main-line station for destinations across the east of England, including Norwich, Southminster, Ipswich, Clacton-on-Sea, Colchester, Chelmsford, Southend Victoria, Cambridge, Harlow Town, Hertford East, and many suburban stations in north and east London, Essex and Hertfordshire. A few daily express trains to Harwich International provide a connection with the Dutchflyer ferry to Hook of Holland. Stansted Express trains provide a link to Stansted Airport and Southend Victoria-bound services stop at Southend Airport.

Most passenger services on the Great Eastern Main Line are operated by Greater Anglia. Since 2015, the Shenfield "metro" service has been controlled by TfL Rail and the Lea Valley Lines to Enfield Town, Cheshunt (via Seven Sisters) and Chingford are operated by London Overground. A small number of late-evening and weekend services operated by c2c run via Barking. The station is split into two-halves: the "west" side for the Lea Valley Lines services and the "east" side for services via Stratford.

London Post Office Railway station
The Liverpool Street Post Office Railway station is a disused station that was operated by Royal Mail on the London Post Office Railway system.

The station is between Mount Pleasant Mail Centre and Whitechapel Eastern District Post Office, and is situated at the south end of Liverpool Street under the Great Eastern Hotel. It opened in December 1927; lifts on either side of the station as well as chutes enabled the transfer of mail to and from the main station. Two 315 ft parcel and letter bag conveyors were connected to platforms 10 and 11 (currently used by Greater Anglia); postal traffic reached 10,000 bags daily in the 1930s, with 690 Post Office services calling. The system was discontinued in 2003.

In 2014, a team from the University of Cambridge began conducting a study in a short, double track section of unused tunnel near the platforms where a newly built tunnel for Crossrail is situated almost two metres beneath. The study is to establish how the original cast-iron lining sections, which are similar to those used for many miles of railway under London, resist possible deformation and soil movement caused by the developments.
