Arnos Grove (/ˈɑːrnɒsˈɡroʊv/) is aLondon Underground station. It is located inArnos Grove in theLondon Borough of Enfield,North London. The station is on thePiccadilly line, betweenBounds Green andSouthgate stations. It is inLondon fare zone 4.[8]
The station opened on 19 September 1932 as the most northerly station on the first section of thePiccadilly line extension fromFinsbury Park toCockfosters. It was the terminus of the line until services were further extended toOakwood on 13 March 1933. When travelling from east ofBarons Court and throughCentral London, Arnos Grove is the first surface station after the long tunnel section of the Piccadilly line. The station has four platforms which face three tracks.
The station was designed by architectCharles Holden, and has been described as a significant work ofmodern architecture. On 19 February 1971, the station wasGrade II listed. In 2005, the station was refurbished with the heritage features also maintained. In July 2011 Arnos Grove's listed status was upgraded to Grade II*.[9] The station was awarded with the Best Newcomer and the Best Overall Garden in the Underground in Bloom 2011 competition and also in the London in Bloom competition.
The station is located on A1110 Bowes Road, serving a medium-sized residential area. Arnos Grove is the first surface station after the long tunnel section which starts east ofBarons Court and passes throughCentral London.[10] The station and surrounding neighbourhood of Arnos Grove take their names from the Arnos Grove estate, which was to the north of the station.[1] The station is part of the Arnos Grove group of stations, comprising all seven stations from Cockfosters to Turnpike Lane, and the management office for the group is in Arnos Grove station. Linked to the station by a lineside passageway is Ash House, which is a drivers' depot. Nearby attractions include Arnos Park, Broomfield School and Bowes Road Library.[11] Arnos Grove is known for its circular ticket hall and as a quiet, peaceful and green neighbourhood until the 1960s. When the Piccadilly line extension came, Edwardian villas were built in the area.[12]
TheGreat Northern Railway (GNR) and its successor, theLondon and North Eastern Railway (LNER), for many years refused consent for any extension into the suburbs ofHaringey andEnfield. In 1902, parliamentary approval was obtained to ban any further extensions of London Underground lines northwards from Finsbury Park. This created a bottleneck at Finsbury Park, back then the northern terminus of the Piccadilly line.[note 1] By 1923, a public campaign against the 1902 parliamentary ban emerged, and Frank Pick had risen to assistant managing director of the Underground group. To help address this issue, Frank Pick gathered photographs of the congestion at Finsbury Park and distributed to the press. In 1925, the LNER gave in to the objection. Pick began working on the extension proposal and obtained parliamentary approval in 1929. The alignment was based on the absence of property development along the line. Funding was obtained from legislation under theDevelopment (Loan Guarantees and Grants) Act 1929 instead of the Trade Facilities Act. Tunnel rings, cabling and concrete were produced in Northern England, while unemployed industrial workers there helped in the construction of the extension.[13] 22 tunnelling shields were used during construction which started in 1930. The station was opened on 19 September 1932 as the terminus on the first section of thePiccadilly line extension to Cockfosters. The line was further extended toOakwood on 13 March 1933.[10] Its name was chosen after public deliberation: alternatives were"Arnos Park","Bowes Road" and"Southgate".[14]
On the night of 13 October 1940, during the Blitz, a lone German aircraft dropped a single bomb on houses to the north of Bounds Green station. The destruction of the houses caused the north end of the westbound platform tunnel to collapse.[15] As a result, train services between Wood Green and Cockfosters were disrupted for two months. On 11 August 1948, a passenger train was derailed when the front and rear bogies of a carriage took different routes at a set of points at the station.[16] On7 July 2005, a bomb exploded on a train travelling between King's Cross St. Pancras and Russell Square. Train services betweenHyde Park Corner and Arnos Grove were disrupted until 4 August of the same year.[10]
Like the other stationsCharles Holden designed for the extension, Arnos Grove was built in amodern European style using brick, glass andreinforced concrete and basic geometric shapes.[7] A circular drum-like ticket hall of brick and glass panels rises from a low single-storey structure and is capped by a flat concrete slab roof.[7] The design was said to be inspired by theStockholm City Library and Swedish architectGunnar Asplund,[17][note 2], althoughCharles Hutton, Holden's chief assistant stated Holden based the idea on a groundsman's lodge at Midhurst Sanatorium designed by Adams, Holden, and Pearson in 1904–1906.[19] The centre of the ticket hall is occupied by a disused ticket office (a passimeter in London Underground parlance)[20] which houses an exhibition on the station and the line. The original design by Holden was detailed byCharles Hutton, who also had to amend the construction method fromSudbury Town tube station due to issues with leaking shuttering for the concrete roof discolouring the brickwork.[19]

Three parallel train tracks pass through the station, with two double-sided platforms between the central track and the outer tracks.[10] The edges of the platforms are labelled platform 1 and 2, and platform 3 and 4, in such a way that the two outer tracks are accessible from platforms 1 and 4, and the central track, usually used by trains that terminate and reverse at Arnos Grove station, is accessible from platforms 2 and 3.[10] Platforms 1 and 2 are designated for trains toCockfosters while platforms 3 and 4 are for trains toCentral London.[10]
When operating a shuttle service between Arnos Grove and Cockfosters, the central track is used exclusively as it has access to both running tracks to/from Southgate (the outer tracks do not have this access).
In July 2011 Arnos Grove became a Grade II*listed building.[21] The building is one of the 12 "Great Modern Buildings" profiled inThe Guardian during October 2007.[22][note 3] Arnos Grove Drivers' Depot won Best Newcomer and Best Overall Garden in the Underground in Bloom 2011 competition[23] for their new project which also got them an award in the London in Bloom competition. Their website[24] tells the whole story with photographs of the garden and the awards ceremonies.
In 2005 the station underwent a refurbishment programme[25] including improvements to signage, security and train information systems. General repairs and redecoration were carried out, flooring was renewed, and better lighting, an improved CCTV security system and Help Points were installed, with the latter being suitable for people with limited hearing. Some of the original signs are in a 'petit-serif' adaptation of theLondon Undergroundtypeface,Johnston Delf Smith Sans.[20] This typeface was designed byCharles Holden andPercy Delf Smith, a former pupil ofEdward Johnston.[26][27][28]
During the refurbishment programme, all these heritage features were maintained as well:[20]

Arnos Grove station is on the Piccadilly line betweenBounds Green to the west andSouthgate to the east. A Piccadilly line journey between Arnos Grove and Southgate typically takes slightly more than four minutes.[29] Train frequencies vary throughout the day, but generally operate every 3–9 minutes between 07:07 and 01:07 eastbound,[30] and every 2–6 minutes between 05:19 and 00:06 westbound.[31] When operational problems occur on the line, Arnos Grove station may act as a temporary terminus of a reduced service – either a shuttle service between Arnos Grove and Cockfosters or a truncated service from Central London.[10] The station has a set of seven sidings to its south for stabling trains.[11][32]
