London Underground Hammersmith & City Line

London Underground Hammersmith & City Line is a Transport for London operated tube line in London, England. Running between Hammersmith and Barking, it is coloured pale pink on the Tube map, it serves 29 stations over 15.8 miles (25.5 km).

Between Farringdon and Aldgate East it skirts the City of London, the capital's financial heart, hence the line's name. Its tunnels are just below the surface and are a similar size to those on British main lines. Most of the track and all stations are shared with either the District, Circle or Metropolitan lines, the other parts of London Underground's sub-surface railway, and over 114 million passenger journeys are made each year on the Hammersmith & City and Circle lines.

The line runs parallel to the Great Western Main Line between Paddington and Westbourne Park, and parallel to the London, Tilbury and Southend Railway between West Ham and Barking.

History
In 1863, the Metropolitan Railway began the world's first underground railway service between Paddington and Farringdon with wooden carriages and steam locomotives. The following year, a railway west from Paddington to Hammersmith was opened and this soon became operated and owned jointly by the Metropolitan and Great Western Railway companies. The line was then extended to the east, in stages, reaching the East London Railway in 1884. The line was electrified in 1906, and, in 1936, after the Metropolitan Railway had been absorbed by the London Passenger Transport Board, some Hammersmith & City line trains were extended over the former District Railway line to Barking. The Hammersmith & City route was shown on the Tube map as part of the Metropolitan line until 1990, since when it has appeared as a separate line.

On 28 September 1970, C69/77 Stock trains were introduced.

In July 2012, brand new S7 Stock trains were introduced.

On 29 June 2014, the C69/C77 Stock trains were withdrawn and the line was converted to a full S7 Stock operation.
