 East Finchley station was built by the Edgware , Highgate and London Railway ( EH & LR ) on its line from Finsbury Park station to Edgware station . Before the line was opened it was purchased in July 1867 by the larger Great Northern Railway ( GNR ) , whose main line from King 's Cross ran through Finsbury Park on its way to Potters Bar and the north . The station , originally named East End , opened along with the railway to Edgware on 22 August 1867 . The station was given its current name in 1886 .
