Railway station in opened 1 March 1899 by the Great Eastern Railway on their Main Line which opened sixty years earlier.
Before the London Underground's Central line was extended from Stratford via Gants Hill to Newbury Park in 1947, Seven Kings was one of two junctions for the Fairlop Loop to Woodford via Hainault. Seven Kings West Junction (used for freight, excursion and empty stock traffic) was closed in 1956, though the other connection, from Ilford, was severed as early as 1947 due to the expansion of Ilford Carriage Sheds, which are easily visible from the western end of Seven Kings station. The carriage sheds comprise a large depot which includes two workshops.
It is proposed that the Crossrail line will stop here. The station is in Travelcard Zone 4.
