Station Information
Forest Gate railway station is located in the London Borough of Newham, in East London.
It is in Travelcard Zone 3 on the Great Eastern Main Line, and was first opened in 1840, a year after the line was built, but closed in 1843, before re-opening after pressure from local residents on 31 May 1846.
The station, and all trains serving it, is operated by Abellio Greater Anglia.
The typical off-peak service is six trains per hour to Liverpool Street and six trains per hour to Shenfield. Of the four platforms, those serving the fast lines are only in operation during engineering works affecting the slow lines.
The station is a short distance (330m according to TfL's journey planner) from Wanstead Park station on the Gospel Oak to Barking Line, and is a suggested interchange in the National Rail Timetable.
