St Ann's Road railway station was opened by the Tottenham & Hampstead Junction Railway on 2 October 1882. It was at the corner of St Ann's Road and Seven Sisters Road in N15, in south west Tottenham, London.
It comprised two wooden platforms, accessed by a footbridge and stairs, and a brick building.
The service at the station was generally between St Pancras or Kentish Town and Barking or Southend, however at times trains ran to some other destinations including Cambridge, Chingford and Victoria.
It was never well used, mainly as it was near South Tottenham and Seven Sisters stations, the latter gave a much faster link to The City. The station was closed on 9 August 1942 as a wartime austerity measure and never reopened. The station building survives, used by a newsagent which is a Transport for London (TfL) ticketstop, so it is possible since the line become part of the London Overground run by TfL in 2007 to buy tickets in the station for passing trains which no longer stop there.
