Canonbury railway station

Canonbury railway station serves the districts of Canonbury and Highbury within the London Borough of Islington in north London. It is on London Overground's North London line and East London line. The station and all trains serving it are operated by London Overground, and the station is in Travelcard Zone 2. This location of the station is close to the boundary with the London Borough of Hackney.

History
The station was originally named "Newington Road and Balls Pond Road" when opened in 1858 by the North London Railway, and was sited east of the present station on the east side of Newington Green Road. The station was renamed "Canonbury" in July 1870 and then resited to its present location, the west side of Douglas Road (now Wallace Road), in December of the same year. The Victorian main building was demolished in 1969, although the building was fully intact.

In 2007, the ticket office was extensively refurbished, as part of the station upgrade programme delivered through conversion to London Overground. On 1 June 2010, as a result of the East London Line extension, North London line services were rerouted to the newly constructed platforms 3 and 4, with the East London line trains now using refurbished platforms 1 and 2.

To the west of the station is the Canonbury curve, a freight-only connection through the Canonbury tunnel to the East Coast Main Line at which had opened in 1874. A passenger service operated to/from Broad Street from 1875 until 1976 when suburban services from the main line were diverted to Moorgate via the newly built surface connection between Finsbury Park and Drayton Park.

Between 14 May 1979 and 11 May 1985 the station was served by the Crosstown Linkline diesel multiple unit service between Camden Road and North Woolwich.

The North London Line between Gospel Oak and closed in February 2010, for installing a new signalling system and for extending 30 platforms, in order in due course to allow four-car trains to run on the London Overground network. After reopening on 1 June 2010, the work continued until May 2011 with a reduced service operating Mondays to Saturdays and no service at all on Sundays.

During the NLL closure of February–May 2010, the through route was moved to the north side of the cutting, and two adjacent brand new platforms provided, an island platform replacing the former eastbound platform. This allowed the extended ELL to serve Canonbury (and Highbury & Islington) on a pair of completely segregated tracks occupying the former route on the south side of the cutting.

Since the northern extension of the East London Line, which was completed and opened in March 2011, Canonbury station has had four platforms, giving interchange between the London Overground East London line (ELL) and North London line (NLL) with step-free access to all platforms and peak service frequencies of 12 trains per hour in each direction.
