The station was opened on 10 January 1863 as the terminus of the original
Metropolitan Railway, the world's first underground
metro line. The station, initially named
Farringdon Street, was originally a short distance from the present station building. The line ran from the
Farringdon area to , a distance of . The station was relocated on 23 December 1865 when the Metropolitan Railway opened an extension to
Moorgate. It was renamed
Farringdon & High Holborn on 26 January 1922 when the new building by the architect
Charles Walter Clark It was built in conjunction with a freight station to take
livestock to a slaughterhouse to its south-east to supply
Smithfield Market; remains of cattle ramps on a street outside the market, West Smithfield. Smithfield was redesignated as a wholesale 'deadmeat' market in the 19th century and the freight station was last used in the 1920s. The lines from Farringdon towards
King's Cross St. Pancras run alongside the
Fleet ditch,
culverted since 1734. The station building is unusually well-preserved early 20th-century London Underground architecture. It retains indications of the Metropolitan Railway's main-line style operation such as a sign for a parcel office on the outer wall and some original signage, with the 1922–1936 name on the facade. After the bay platforms at closed on 21 March 2009,
Southeastern services that previously terminated at Blackfriars were extended to ,
St. Albans,
Luton or
Bedford, calling at this station.
Thameslink trains to Moorgate ceased at the same time.
Recent and current developments Farringdon has recently received significant upgrades to allow it to meet the needs of a series of major rail upgrade projects: The
Thameslink Programme was a major upgrade to the existing north-south Thameslink route, enabling longer and more frequent trains, completed in 2018; and the
Four Lines Modernisation involves the wholesale resignalling of the London Underground's sub-surface lines bringing a major boost in capacity to Circle, Hammersmith & City and Metropolitan line services calling at Farringdon. In addition the station has been significantly expanded to serve as a stop on the new east-west
Elizabeth line providing interchange between Thameslink and the Elizabeth line. Once all these projects have been completed, Farringdon will be one of the country's busiest stations with approximately 200 , an average of one departure every 20 seconds. A new building, housing a dedicated ticket hall, has been constructed to serve these extra passengers. The new building is to the immediate south of the original station, which itself has been upgraded as part of the programme. An additional entrance has also been built at the north end of the original station, onto
Turnmill Street.
Thameslink upgrade heads south from Farringdon. On the left is the blocked-off
City Widened Line branch to , closed as part of the
Thameslink Programme. Farringdon Station has been rebuilt to accommodate longer Thameslink trains and to make other improvements to the station. The existing station building has been refurbished with a new roof canopy covering the north end of all four platforms and a new entrance and concourse facing Turnmill Street. An additional ticket hall has been built on the south side of
Cowcross Street providing access to the Thameslink platforms, which have been extended southwards underneath this building, allowing the station to handle 240 m (12-carriage) trains. Platforms have been widened to accommodate increased passenger numbers. This process required the bridge that formed Cowcross Street to be demolished and rebuilt. Cowcross Street is now pedestrianised. Lifts have been provided throughout. The existing listed ticket hall and concourse have been remodelled, for use by London Underground and Thameslink passengers. Interchange within the station has been improved by removing the interchange bridge and installing new stairs and lifts with access to all four platforms, allowing passengers with impaired mobility to use the station. It was necessary to build the Thameslink platform extensions to the south, since there is a sharp gradient to the immediate north of the station. This resulted in the two-station branch to
Moorgate being permanently closed. The platform extensions cross the former Moorgate line and reach within a few metres of the entrance of the
Snow Hill Tunnel. The alternative of realigning both the Thameslink and Circle/Hammersmith & City/Metropolitan lines was impractical as the latter crosses over the former on a bridge almost immediately to the north of the station. Access at the Farringdon end is via the new Thameslink ticket hall. but the scheduled opening date was delayed. From 24 May 2022 the new railway line linked Farringdon to
Abbey Wood via
Canary Wharf in the east and
Paddington, in the west. The station is also a hub for cross-London travel, being the only station to be on both the north-south Thameslink service and the east-west Elizabeth line service. Direct Elizabeth line services between Reading/Heathrow in the west and Shenfield (via Whitechapel and Stratford) started in late 2022. ==Dual traction current supply==
