Holborn tube station
Holborn ( ) is a London Underground station in Holborn, Central London, located at the junction of High Holborn and Kingsway. It is served by the Central and Piccadilly lines. On the Central line the station is between Tottenham Court Road and Chancery Lane stations; on the Piccadilly line it is between Covent Garden and Russell Square and is in Travelcard Zone 1. Close by are the British Museum, Lincoln's Inn Fields, Red Lion Square, Bloomsbury Square, London School of Economics and Sir John Soane's Museum. Located at the junction of two earlier tube railway schemes, the  station was opened in 1906 by the Great Northern, Piccadilly and Brompton Railway (GNP&BR). The station entrances and below ground circulation were largely reconstructed for the introduction of escalators and the opening of Central line platforms in 1933, making the station the only interchange between the lines. Before 1994, Holborn was the northern terminus of the short and little-frequented Piccadilly line branch to Aldwych and two platforms originally used for this service are disused. One of the disused platforms has been used for location filming when a London Underground station platform is needed. History. Planning. The station was planned  by the Great Northern and Strand Railway (GN&SR), which had received parliamentary approval for a route from Wood Green station (now Alexandra Palace) to Strand in 1899. After the GN&SR was taken over by the Brompton and Piccadilly Circus Railway (B&PCR) in September 1901, the two companies came under the control of Charles Yerkes' Metropolitan District Electric Traction Company before being transferred to his new holding company, the Underground Electric Railways Company of London (UERL) in June 1902. To connect the two companies' planned routes, the UERL obtained permission for new tunnels between Piccadilly Circus and Holborn. The companies were  formally merged as the Great Northern, Piccadilly and Brompton Railway following parliamentary approval in November 1902. Construction. The linking of the GN&SR and B&PCR routes at Holborn meant that the section of the GN&SR south of Holborn became a branch from the main route. The UERL began constructing the main route in July 1902. Progress was rapid, so that it was largely complete by the Autumn of 1906. Construction of the branch was delayed while the London County Council carried out slum clearances to construct its new road Kingsway and the tramway subway running beneath it and while the UERL  decided how the junction between the main route and the branch would be arranged at Holborn. When originally planned by the GN&SR, Holborn station was to have just two platforms. The first GNP&BR plan for the station would have seen the two platforms shared by trains on the main route and by the shuttle service on the branch with the junctions between the tunnels south of the station. The interference that shuttle trains would have caused to services on the main route led to a redesign so that two northbound platforms were provided, one for the main line and one  for the branch line, with a single southbound platform. The junctions between the two northbound tunnels would have been north of the platforms. When powers were sought to build the junction in 1905, the layout was changed again so that four platforms were to be provided. The southbound tunnel of the main route no longer connected to the branch, which was to be provided with an additional platform in a dead-end tunnel accessed from a crossover from the northbound branch tunnel. As built, for ease of passenger access, the branch's northbound tunnel ended in a dead-end platform  adjacent to the northbound main line platform with the branch's southbound tunnel connected to the northbound main line tunnel. To enable the southbound tunnel of the main route to avoid the branch tunnels, it was constructed at a lower level than the other tunnels and platforms. The tunnel towards Covent Garden (at this point heading south-west) passes under the branch tunnels. As with most of the other GNP&BR stations, the station building was designed by Leslie Green, though at Holborn the station frontage was, uniquely, constructed in stone rather than the standard red glazed terracotta. This was due  to planning regulations imposed by the London County Council which required the use of stone for façades in Kingsway. The station entrance and exit sections of the street façade were constructed in granite with the other parts of the ground and first floors in the same style, but using Portland stone. The rest of the building above first floor level was constructed contemporaneously with the station. Access to the platform levels of the station was provided by trapezium-shaped electric lifts manufactured by Otis in America. These operated in pairs in shared circular shafts, with an escape stair in a  separate, smaller shaft. Although the station was constructed where the GNP&BR's tunnels crossed those of the Central London Railway (CLR, now the Central line) running under High Holborn, no interchange between the two lines was made as the CLR's nearest station, British Museum, was to the west. Passengers wishing to interchange between the two stations had to do so at street level. The station opened on 15 December 1906, although the opening of the branch was delayed until 30 November 1907. Until the 1960s the station was named Holborn (Kingsway). The suffix was only gradually dropped, as it  was still displayed on the platform roundels until the 1980s. 1930s station modernisation. The street level interchange between the GNP&BR and CLR involving two sets of lifts was considered a weakness in the network. A below ground subway connection was considered in 1907. A proposal to enlarge the CLR's tunnels to create new platforms at Holborn station and to abandon British Museum station was included in a private bill submitted to parliament by the CLR in November 1913, although the First World War prevented any works taking place. Like many other central London Underground stations, Holborn was modernised in  the early 1930s to replace the lifts with escalators. The station frontages on Kingsway and High Holborn were partially reconstructed to modernist designs by Charles Holden with the granite elements replaced with plain Portland stone façades perforated with glazed screens. The lifts were removed and a spacious new ticket hall was provided giving access to a bank of four escalators down to an intermediate concourse for the Central line platforms. A second bank of three escalators continues down to the Piccadilly line platforms. To construct the new Central line platforms, the larger diameter station tunnels were manually excavated around the  existing running tunnels whilst trains continued to run. When the excavations were complete, the original segmental tunnel linings were dismantled. The new platforms came into use on 25 September 1933 replacing those of British Museum, which had closed the day before. As part of the modernisation the station was renamed "Holborn (Kingsway)" on 22 May 1933, but the suffix gradually dropped out of use and no longer appears on station signage or tube maps. The new platforms at Holborn led to the number of passengers switching between the lines increasing tenfold by 1938. Mural additions in the 1980s. The station  was redecorated in the 1980s, with platform walls lined with panels of enamelled metal forming murals designed by Allan Drummond that reference the British Museum. These murals reference Egyptian and Roman antiquities, with sarcophagi, statues and trompe-l'œil columns on the walls of the platform. Branch operations. Initially, shuttle train services on the branch operated from the through platform at Holborn. At peak times, an additional train operated alternately in the branch's western tunnel from the bay platform at Holborn. During the first year of operation, a train for theatregoers operated late on Monday to Saturday evenings from Strand  through Holborn and northbound to Finsbury Park; this was discontinued in October 1908. In March 1908, the off-peak shuttle service began to use the western tunnel on the branch, crossing between the two branch tunnels south of Holborn. Low usage led to the withdrawal of the second peak-hour shuttle and the eastern tunnel was taken out of use in 1914. Sunday services ended in April 1917 and, in August of the same year, the eastern tunnel and the bay platform at Holborn were formally closed. Passenger numbers on the branch remained low: when the branch was considered for  closure in 1929, its annual usage was 1,069,650 and takings were £4,500. The branch was again considered for closure in 1933, but remained open. Wartime efficiency measures led to the branch being closed temporarily on 22 September 1940, shortly after the start of The Blitz, and it was partly fitted out by the City of Westminster as an air-raid shelter. The tunnels were used to store items from the British Museum, including the Elgin Marbles. The branch reopened on 1 July 1946, but patronage did not increase. In 1958, London Transport announced it would be closed. Again it  survived, but the service was reduced in June 1958 to run only during Monday to Friday peak hours and Saturday morning and early afternoons. The Saturday service was withdrawn in June 1962. After operating only during peak hours for more than 30 years, the closure announcement came on 4 January 1993. The original 1907 lifts at Aldwych required replacement at a cost of £3 million. This was not justifiable as only 450 passengers used the station each day and it was losing London Regional Transport £150,000 per year. The Secretary of State for Transport granted permission on 1  September 1994 to close the station and the branch closed on 30 September. After its closure in 1917, the bay platform was converted into rooms for use, at various times, as offices, air-raid shelters, store rooms, an electrical sub-station and a war-time hostel. Since 1994, the branch's remaining platform at Holborn has been used to test mock-up designs for new platform signage and advertising systems. Future developments. In the aftermath of the King's Cross fire in 1987, the Fennell Report into the disaster recommended that London Underground investigate "passenger flow and congestion in stations  and take remedial action". A private bill was submitted to parliament and approved as the "London Underground (Safety Measures) Act 1991" giving London Underground powers to improve and expand the frequently congested station with a new ticket hall and new subways. The expansion works were not carried out and the arrangement of the station remains much the same as it was in the 1930s. According to Transport for London (TfL), the station is at capacity because of the large number of passengers leaving and entering the station, as well as the large numbers of passengers changing between lines. Currently, everyone  who uses the station has to pass through the intermediate concourse at the bottom of the main escalators. This causes congestion and delays. In September 2017, TfL proposed various station improvements including a second entrance on Procter Street to the north-east of the station, lifts to provide step free access, and new tunnels to improve the interchange between the Central and Piccadilly lines. Owing to the delay in the opening of Crossrail and the subsequent knock on effect on TfL's Business Plan, the upgrade to Holborn station is now not expected to commence until 2023/24, with the works  taking around six years to complete, doubling the size of the station. Incidents and accidents. The Holborn rail crash occurred on the Central line at Holborn on 9 July 1980, at about 13:28 and involved two 1962 stock trains. The 13:17 train from Liverpool Street to White City, standing at the westbound platform, was run into by the 12:49 Hainault to Ealing Broadway train. The rear train was slowing after its brakes had been applied by the emergency train stop system because it had passed two signals at danger, but it failed to stop in time to avoid collision. The  driver of the rear train and 20 passengers were injured. An inquiry concluded that the accident was caused by the driver failing to control his train. Disruption of services occurred until the following morning. On 21 October 1997, a 9-year-old boy, Ajit Singh, was dragged to his death after a toggle on his anorak was trapped in the closing doors of a Piccadilly line train. Use in media. The disused branch line platform and other parts of the station have been used in the filming of music videos for Howard Jones' "New Song", Leftfield's "Release the Pressure , Suede's Saturday Night" and Aqua's "Turn Back Time". The pre-war operation of the station and the branch line features in a pivotal scene in Geoffrey Household's novel "Rogue Male", when the pursuit of the protagonist by enemy agents sees them repeatedly using the station's escalators, passageways and the shuttle service. Use in Particle Physics. Patrick Blackett (who won the Nobel Prize for his discovery of the positron), following a row with his mentor Lord Rutherford at Cambridge University developed plans to install a cosmic ray detector on an abandoned platform of the Holborn Station. The  plans included a huge 11 ton magnet and a cloud chamber, and was hailed by the London tabloid press at the time as the efforts of a "new 'Sherlock Holmes', hunting beneath the streets of London for clues about the mysteries of the universe." Services. The station is in London fare zone 1. On the Central line the station is between Tottenham Court Road and Chancery Lane, and on the Piccadilly line, it is between Covent Garden and Russell Square. Holborn is the only direct interchange between these lines. Train frequencies vary throughout the day, but generally Central line trains  operate every 2–6 minutes from approximately 05:53 to 00:30 westbound and 05:51 to 00:33 eastbound. Piccadilly line trains operate every 2–6 minutes from approximately 05:42 to 00:28 westbound and 05:54 to 00:38 northbound. On the Central line 1992 Stock is used. On the Piccadilly line 1973 Stock is used. Connections. Historical tram connections. Before the closure of the original London tram network in 1952, Holborn tube station provided an interchange between trams and tubes, via the Kingsway Tramway Subway underground Holborn tramway station located a little distance south of the underground station. This was the only part of London with  an underground tram system, and Holborn tramway station (named Great Queen Street when first opened) is still extant beneath ground, though with no public access. Current bus connections. London Buses routes 1, 59, 68, 91, 168, 188, 243, 521 and X68 and night routes N1, N25, N68, N91 and N171 serve the station.
