Gospel Oak railway station is in the borough of Camden in north London. It is on the North London Line (NLL) and is also the western passenger terminus of the Gospel Oak to Barking Line. Passengers using Oyster cards are required to tap on interchange Oyster card readers when changing between the two lines. The station is in Travelcard Zone 2, and is managed by London Overground which runs all passenger trains at the station.
To allow four-car trains to run on the London Overground network, the North London Line between this station and Stratford closed from February 2010 to 1 June 2010, for installing a new signalling system and for extending 30 platforms. Until May 2011, there was a reduced service with no services on Sundays while the upgrade work continued.
