The Tottenham & Hampstead Junction Railway was a railway line in north London, formed by an Act of Parliament of 28 July 1862, and was effectively part of an attempt by the Great Eastern Railway to obtain a west end terminus, alongside Bishopsgate Station in east London. The line opened on 21 July 1868 between Tottenham North Junction (on the Great Eastern Railway) and Highgate Road. An extension to Kentish Town Station opened in 1870. An extension to Gospel Oak Station opened on 4 June 1888. More information on the Wikipedia page [1].
