Since then it has carried East London Line services between Shoreditch High Street and Dalston.
Previously the North London Line's access from west of Dalston to the City was by a circuitous route via Hackney, Homerton, Bow and Stepney to Fenchurch Street.
The extension, originally with three lines, shortened this considerably by providing a direct route from Dalston over the Kingsland Viaduct.
The lines were electrified with two conductor rails at 600 V DC, with services beginning on 1 October 1916, using Oerlikon rolling stock.
[1][2] The plan received the support of a public inquiry in 1994 and it was envisaged that the construction of the extension and the station itself would begin in 1996, to be completed by 1998.
