Clerkenwell was an authorised underground railway station planned by the Metropolitan Railway but never built. It was to be located on Farringdon Road at Mount Pleasant in Clerkenwell, London.
The Metropolitan Railway (MR, now the Metropolitan line) opened in 1863 between Paddington and Farringdon as the world's first underground railway line. The railway was mostly constructed using cut and cover techniques under existing roads, though the section through Clerkenwell under Mount Pleasant hill was constructed using traditional tunnelling methods because of the depth of the tracks beneath the surface. Because of the depth, and the lack of development in the immediate area (until the 1880s the hill was the site of Coldbath Fields Prison), no station was constructed at Clerkenwell, leaving a greater distance between King's Cross (since replaced by King's Cross St Pancras further to the west) and Farringdon stations than between others on the railway.
In November 1910, the MR submitted a private bill to parliament that included plans to construct a new station at Mount Pleasant.  The station would have been 60 feet (18 m) below ground. Parliamentary approval for the station was granted in the Metropolitan Railway Act 1911; however, the powers were not used and they lapsed in 1932. 
The Metropolitan line, colloquially known as the Met, is a London Underground line between Aldgate in the City of London and Amersham and Chesham in Buckinghamshire, with branches to Watford in Hertfordshire and Uxbridge in Hillingdon. Printed in magenta on the tube map, the line is 41.4 miles (66.7 km) in length and serves 34 stations. Between Aldgate and Finchley Road, the track is mostly in shallow "cut and cover" tunnels, apart from short sections at Barbican and Farringdon stations. The rest of the line is above ground, with a loading gauge of a similar size to those on main lines. Just under 67 million passenger journeys were made on the line in 2011/12.
The Circle line is a spiral-shaped London Underground line, running from Hammersmith in the west to Edgware Road and then looping around central London back to Edgware Road. The railway is below ground in the central section and on the loop east of Paddington. Unlike London's deep-level lines, the Circle line tunnels are just below the surface and are of similar size to those on British main lines. Printed in yellow on the Tube map, the 17-mile (27 km) line serves 36 stations, including most of London's main line termini. Almost all of the route, and all the stations, are shared with one or more of the three other sub-surface lines, namely the District, Hammersmith & City and Metropolitan lines. On the Circle and Hammersmith & City lines combined, over 114 million passenger journeys were recorded in 2011/12.
The Hammersmith & City line is a London Underground line that runs between Hammersmith in west London and Barking in east London. Printed in 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. Over 114 million passenger journeys are made each year on the Hammersmith & City and Circle lines.
Clerkenwell is an area of central London, England.
The River Fleet is the largest of London's subterranean rivers, all of which today contain foul water for treatment. Its headwaters are two streams on Hampstead Heath, each of which was dammed into a series of ponds—the Hampstead Ponds and the Highgate Ponds—in the 18th century. At the southern edge of Hampstead Heath these descend underground as sewers and join in Camden Town. The waters flow 4 mi (6 km) from the ponds, having as combined sewers taken on foul water, in the Victorian economic but grandiose scheme designed by Joseph Bazalgette to be conveyed by very large sewers to be treated at Beckton Sewage Treatment Works.
Baker Street is a London Underground station at the junction of Baker Street and the Marylebone Road in the City of Westminster. It is one of the original stations of the Metropolitan Railway (MR), the world's first underground railway, opened on 10 January 1863.

Moorgate is a central London railway terminus and connected London Underground station on Moorgate in the City of London.

Farringdon Road is a road in Clerkenwell, London.
The Metropolitan Railway was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the capital's financial heart in the City to what were to become the Middlesex suburbs. Its first line connected the main-line railway termini at Paddington, Euston, and King's Cross to the City. The first section was built beneath the New Road using cut-and-cover between Paddington and King's Cross and in tunnel and cuttings beside Farringdon Road from King's Cross to near Smithfield, near the City. It opened to the public on 10 January 1863 with gas-lit wooden carriages hauled by steam locomotives, the world's first passenger-carrying designated underground railway.
The Metropolitan District Railway, also known as the District Railway, was a passenger railway that served London from 1868 to 1933. Established in 1864 to complete an "inner circle" of lines connecting railway termini in London, the first part of the line opened using gas-lit wooden carriages hauled by steam locomotives. The Metropolitan Railway operated all services until the District Railway introduced its own trains in 1871. The railway was soon extended westwards through Earl's Court to Fulham, Richmond, Ealing and Hounslow. After completing the inner circle and reaching Whitechapel in 1884, it was extended to Upminster in Essex in 1902.
Holborn Viaduct was a railway station in the City of London, providing local and commuter services. It was located to the southeast of Holborn Viaduct, and east of Farringdon Street.
The London station group is a group of 18 railway stations served by the National Rail network in central London. The group contains all 14 terminal stations in central London, either serving major national services or local commuter routes, and 4 other through-stations that are considered terminals for ticketing purposes. All current stations in the group fall within London fare zone 1. A ticket marked "London Terminals" allows travel to any station in the group via any permitted route, as determined by the National Routeing Guide.

Paddington is a London Underground station served by the Circle and Hammersmith & City lines. It is located adjacent to the north side of Paddington mainline station and has entrances from within the mainline station and from Paddington Basin. The station is between Royal Oak and Edgware Road and is in London Fare Zone 1.
The North Western and Charing Cross Railway (NW&CCR) was a railway company established in 1864 to construct an underground railway in London. The NW&CCR was one of many underground railway schemes proposed for London following the opening in 1863 of the Metropolitan Railway, the world's first underground railway, but was one of only a few to be authorised by Parliament. The company struggled to raise funding for the construction of its line and was twice renamed, to the Euston, St Pancras and Charing Cross Railway and the London Central Railway, before the proposals were abandoned in 1874.
