Original structure

Cannon Street station was built on a site where the Hanseatic merchants' steelyard had been based from the 10th century until 1598.^[8] The site was proposed in 1860 by the South Eastern Railway (SER) in response to its rival, the London, Chatham & Dover Railway (LC&DR), extending a line into the City of London as far north as Ludgate Hill. The SER had already made plans to extend its line towards Charing Cross, but decided that it should complement this with a terminus in the City.^[9]

In 1861, the company obtained an act for a station in Cannon Street, a short distance from Mansion House and the Bank of England.^[9] In addition to taking traffic from the LC&DR, the new station would provide a direct railway link between the City and the West End, over which a journey could be made in a fraction of the time taken travelling by road.^[10] The approach was a 60-chain (4,000 ft; 1,200 m) branch of the line to Charing Cross, west of London Bridge. Work started on the station and its approach in July 1863.^[11] The construction work was undertaken by Lucas Brothers.^[12]

The station was opened on 1 September 1866^[11] at a cost of £4 million (now £394 million).^[13] The original building was designed by Sir John Hawkshaw and John Wolfe-Barry and was characterised by its two Christopher Wren-style towers, 23 ft (7.0 m) square and 135 ft (41 m) high, which faced on to the River Thames. The towers supported an iron train shed, 700 ft (210 m) long and crowned by a high single arch, almost semicircular, of glass and iron. The station is carried over Upper Thames Street on a brick viaduct, 700 ft (210 m) long and containing 27 million bricks.^[14] Below this viaduct exist the remains of a number of Roman buildings, which form a scheduled monument.^[15] The bridge was open to pedestrians between 1872 and 1877; they paid a toll of ½d.^[11]

The five-storey City Terminus Hotel, which fronted the station, was opened in May 1867. It was an Italianate style hotel and forecourt, designed by E. M. Barry, and it provided many of the station's passenger facilities, as well as an appropriate architectural frontispiece to the street. This arrangement was very similar to that put in place at Charing Cross.^[16] The hotel was also built by Lucas Brothers.^[12] The hotel was not profitable, and was over £47,000 (now £4,784,000) in debt by 1870.^[17] The City Terminus Hotel was renamed the Cannon Street Hotel in 1879.^[5] In July 1920, the hotel was the venue for the Foundation Congress of the Communist Party of Great Britain. Most of the hotel was closed in 1931, but the public rooms were kept open for meetings. The rest were converted into offices and renamed Southern House.^[16] The hotel is referred to in The Fire Sermon section of T. S. Eliot's The Waste Land.^[18]

Upon its opening Cannon Street station was a stopping point for all services to and from Charing Cross, including boat trains to Continental Europe. A shuttle service between the two stations ran every 20 minutes and became a popular way of travelling between the City and the West End.^[16] However, the opening of the District Railway as far as Blackfriars caused traffic to decline, and its extension to Mansion House the following year reduced it further. The SER's route could not compete with the Underground, which was more direct and reliable,^[19] but suburban traffic to Cannon Street remained popular, and the bridge was widened to 120 feet (37 m) in the late 1880s, allowing ten tracks with sidings. The rebuilt bridge was opened on 13 February 1892.^[20] The signal boxes outside the station were upgraded the following year.^[21]

The SER merged with the LC&DR in 1899 to form the South Eastern and Chatham Railway (SECR). The following year, the station was earmarked for part-time closures as it relied primarily on business travel, but this was rejected. A further proposal was a monorail running between London Bridge and Cannon Street, at an estimated cost of £100,000; this was also abandoned.^[22] The London and Southwestern Railway (LSWR) became interested in using Cannon Street as a terminus, as it would allow a connection between Waterloo and the City.^[23]

War years

Work on strengthening the bridge, by the addition of six new 443-foot (135 m) girders in between the existing ones, was completed in 1913.^[20]

Most Cannon Street train services ceased during World War I. Continental boat trains were stopped on 15 November 1914 and rerouted to Victoria. The station stopped being served by through services from Charing Cross on 31 December 1916, and was closed on Sundays. Services were reduced further on 1 May 1918, when it was closed after 3 p.m. on Saturdays and between 11 a.m. and 4 p.m. Mondays to Fridays. This allowed Cannon Street to be used as a goods depot for war supplies.^[24]

Between 5 and 28 June 1926, the station was closed to allow the Southern Railway to carry out various works, including the rebuilding of the platforms, relaying of the tracks and installation of a new system of electrical signalling – the four-aspect colour light scheme. The station was also renovated and the glass roof cleaned. The number of platforms was reduced from nine to eight, with five set aside for the new electric trains. The signal box spanning the width of the railway bridge was removed.^[25] In July 1939, Cannon Street was closed for a week following a fire in Borough Market which prevented any trains accessing it.^[26]

The station, which had been subject to structural neglect prior to World War II, suffered extensive bomb damage and was hit by several incendiary devices which damaged the roof. A high explosive also hit platform 8.^[27] The original glass roof had been removed before the war, in an attempt to save it; however, the factory in which the roof was stored was itself badly bombed, destroying the roof.^[5]

Redevelopment

Following nationalisation of the railways in 1948, the station was managed by the Southern Region of British Railways. The station's prime location coupled with the property boom of the 1950s and the need for British Rail to seek alternative revenue streams made war-damaged Cannon Street a key target for property developers.^[28] Steam trains stopped running from Cannon Street in 1961 ^[29]

Various plans were mooted for the reconstruction of the station, from the installation of a new ticket hall and concourse under Southern House in 1955 as part of British Rail's Modernisation Plan to the construction of a car park estimated to cost £125,000 (now £3,489,000)^[28] and even a helipad.^{[lower-alpha 1][30]} In 1962, the British Transport Commission entered into an agreement with Town & Country Properties for the construction of a multi-storey office building above the station with 154,000 sq ft (14,300 m²) of floor space. The cost of the development was £2.35 million (now £48 million) and it was scheduled for completion by June 1965.^[31]

In preparation for redevelopment, the remains of the train shed roof had been demolished in 1958, and Barry's hotel (which had been used as offices since 1931) soon followed in 1960.^[32] The architect selected to design the new building was John Poulson who was good friends with Graham Tunbridge, a British Rail surveyor whom he had met during the war. Poulson took advantage of this friendship to win contracts for the redevelopment of various British Rail termini. He paid Tunbridge a weekly income of £25 and received in return building contracts, including the rebuilding of Waterloo and East Croydon stations. At his trial in 1974, Poulson admitted that, shortly before receiving the Cannon Street building contract, he had given Tunbridge a cheque for £200 and a suit worth £80.^[33] Poulson was later found guilty of corruption charges and given a seven-year concurrent sentence; Tunbridge received a 15-month suspended sentence and a £4,000 fine for his role in the affair.^[34]

All that now remains of the original station architecture are the twin 120 ft (37 m) yellow brick towers at the country-end and parts of the low flanking walls.^[5]

Modern era

The station's twin brick towers were listed Grade II in 1972.^[35][36] In 1974, the station was closed for five weeks from 2 August to 9 September to enable alterations to be made to the track and the approaches to London Bridge to be resignalled. Traffic was diverted to London Bridge, Charing Cross and Blackfriars.^[37] On 4 March 1976, a Provisional Irish Republican Army (IRA) bomb of about 10 lb (4.5 kg) exploded on an empty commuter train leaving Cannon Street, injuring eight people on another train travelling alongside.^{[lower-alpha 2][38]}

On 15 February 1984, it was reported in The Times that Cannon Street was to close. At the time, the station had been closed for weekends and evenings, and the publication of British Rail's new timetable for 1984–1985 revealed that it would lose all its direct off-peak services to the south-east. Services from Sevenoaks, Orpington, Hayes, Dartford, Sidcup, Bexleyheath, Woolwich, Lewisham and Greenwich would instead terminate at London Bridge except during peak hours.^[39] This was denied by British Rail (Southern)'s manager David Kirby, who pointed out that it had invested £10 million in redecking the railway bridge, and that passengers travelling from the south-east during off-peak hours would most likely be visiting the West End and not the City.^[40]

In 1986, the twin towers were restored in a project costing £242,000 (now £3,397,000). The works revealed that the east tower still contained a large water tank which was used during the days of steam traction to replenish locomotives and to power the station's hydraulic systems. The brickwork was repaired, cleaned and repointed, and the weather vanes gilded to complement the dome of nearby St Paul's Cathedral. This work was one of the Railway Heritage Trust's first projects and coincided with an exhibition held in the station in August of the same year to mark its 150th anniversary.^[41]

In the 1980s, there was another property boom and British Rail again began looking into further commercial uses of the Cannon Street landspace, including 500,000 square feet (46,000 m²) of office space.^[43] The air rights over the platforms to the rear of Poulson's office were sold to Speyhawk which appointed Bovis Construction to build a free-standing structure comprising two office blocks on a 6,000 tonne steel deck constructed over the station's eight platforms.^[5] The Cannons Club, a sports club, was founded beneath the station's arches around this time, and quickly became one of the most prestigious squash clubs in the country. InterCity, the high-speed arm of British Rail, subsequently sponsored the National Squash Championships and National Squash Challenge.^[44]

The larger office block, the "Atrium building", provides 190,000 sq ft (18,000 m²) of office space on six floors and is linked to the smaller building, the "River building", via a glazed link raised through a central glazed atrium. The River building, which has two storeys, is built on the steel deck and contained within the station's two flank walls, which were rebuilt, providing 95,000 sq ft (8,800 m²) of office space. This building projects slightly beyond the restored twin towers which form the riverside boundary to the development.^[45] The Atrium building was later let to the London International Financial Futures and Options Exchange (Liffe). The River building has a 1 acre (0.40 ha) roof garden. The project cost around £500,000 and was laid to comply with planning restrictions which required the building to be low and flat to maintain the sight lines from St Paul's to Tower Bridge.^[46]

Planning permission was granted in March 2007 to replace the Poulson building, with a new air rights building designed by Foggo Associates.^[47] Hines, the US developer, led a £360 million project involving the demolition of Poulson's office block, replacing it with a mixed-use development containing more than 400,000 sq ft (37,000 m²) of office space alongside 17,000 sq ft (1,600 m²) of station retail space.^[15] The redevelopment was part of a larger regeneration programme undertaken by Network Rail to modernise and "unlock the commercial potential" of the main London termini; Euston and London Bridge were also redeveloped. Network Rail's director of commercial property said that the finished station would be "less congested and more accessible for passengers."^[48] Cannon Street won the award for "Major Station of the Year" at the 2013 National Rail Awards.^[49]

In January 2015, the station's opening hours were extended to 0500–0100 Monday to Sunday (prior to this, the station had been closed on Sundays and during the evenings), and several services which previously terminated at Charing Cross were diverted to Cannon Street as a result of Thameslink Programme works. Some of these services reverted to terminating at Charing Cross following the completion of the works, while services from the Greenwich line and from New Cross and St Johns will permanently run to Cannon Street due to the removal of the Spa Road Junction.^[50][51]

Accidents and incidents

• On 26 December 1867, seven passengers and three train crew members were injured when, "during a very thick fog", a train arriving at Cannon Street from Greenwich collided with another from Waterloo due to a signaller's error.^[56]
• On 27 June 1914, one person was killed and 20 were injured in a collision and subsequent derailment at Cannon Street. A train departing for Hastings was in a side-long collision with a train arriving, across its path, from Plumstead and, although the collision occurred at low speed, part of the Plumstead service was derailed and one of its carriages overturned. The driver of the Plumstead service was blamed for a failure to observe, and a misreading of, signals which took his train into the path of the Hastings-bound service. An investigation found the man who died was likely leaning out of the window at the moment his carriage overturned, and he might have avoided serious injury had he been seated.^[57]
• On 16 July 1919, 75 people were injured or left shaken when a train arriving from Dartford hit the buffers at the end of Cannon Street's platform seven. Twelve of the injured required hospital treatment. A Board of Trade report into the incident blamed "an error of judgment" on the driver's part while he was braking on his approach to the platform end.^[58]
• On 11 May 1941, the station was bombed in a Luftwaffe air raid. SR V class 4-4-0 No. 934 St. Lawrence was severely damaged.^[59]
• On 20 March 1951, a diesel electric multiple unit and an electric multiple unit were in a side-long collision when the driver of the latter misread signals.^[60]
• On 5 April 1957, the signal box was destroyed by a fire due to an electrical fault. The station was consequently put out of action. Using hand signals, a skeleton service was put in place on 8 April. A temporary signal box was erected which came into operation on 5 May. Steam locomotives were temporarily banned from using the station, with Hastings Units being introduced into service earlier than planned. A full service was resumed from 6 May. Construction of a new signal box began on 19 April and it came into service on 16 December.^[61]
• On 20 March 1961, a side-long collision and partial derailment resulted in injury to 12 people aboard an arriving service whose driver inadvertently passed a red signal and ran into an empty train as it left Cannon Street.^[62]
• On 4 March 1976, a bomb exploded on an empty electric multiple unit at the station. Eight people in an adjacent train were injured.^[63]
• On 20 August 1989, the Marchioness pleasure boat sank close to Cannon Street Railway Bridge, killing 51 people.^[64]
• On 8 January 1991, two people were killed and hundreds were injured when an electric multiple unit failed to stop on a dead-end platform and collided with the buffers.^[65]

History

By 1876, the Metropolitan Railway (MR) and District Railway (DR) had constructed the majority of the Inner Circle (now the Circle line), reaching Aldgate and Mansion House respectively.^[75] The companies were in dispute over the completion of the route as the DR was struggling financially and the MR was concerned that completion would affect its revenues through increased competition from the DR in the City area. In 1874, city financiers who were keen to see the line completed established the Metropolitan Inner Circle Completion Railway (MICCR) to link Mansion House to Aldgate.^[76][77] Forced into action, the MR bought out the company, and it and the DR began construction of the final section of the Inner Circle in 1879.^[76]

On 6 October 1884, the final section of the Inner Circle was opened, along with Cannon Street station.^[78] Initially, the station was served by trains of both companies as part of the circular Inner Circle service, but various operational patterns have been used during the station's life.^[79] The Inner Circle service achieved a separate identity as the Circle line in 1949, although its trains were still provided by the District or Metropolitan lines.^[80]

A station here was part of the abandoned phase two expansion of the Fleet line (now Jubilee line). It had originally been planned in 1943, and was revived as a major transport plan in 1965.^[81] London Transport spent £10m (now £140m) in 1972 safeguarding the route underneath Cannon Street and building reinforcements for laying a tube in the water-bearing ground around the station. The plan was abandoned in the early 1980s in favour of the current extension further south.^[82]

The Underground station underwent major reconstruction at the same time as the main line station, with the work being completed in 2012. From 14 December 2014, the station's opening hours changed significantly, with the station opening on Sundays and no longer closing early in the evenings.^[83] The station previously had restricted opening hours because it primarily served the local financial services sector, so there was low demand for services outside office hours. However, with the main line station's opening hours being extended due to the Thameslink Programme, the Underground station's opening hours were changed to accommodate the additional passengers.^{[citation needed]}
