Northern line trains are scheduled to arrive and depart every 3–9 minutes from the station's three southbound platforms, with trains operating to Morden via Bank or to Kennington or Morden via Charing Cross. On days when Night Tube service is not running, between about 00:00 and 01:00, departing trains run as far as East Finchley only, from where journeys to central London can be continued by night bus N20, which also serves High Barnet station itself. When trains are no longer required to run on the Northern line, they may be stabled on the sidings to the east of the station.
History
High Barnet station was planned by the Edgware, Highgate and London Railway and was originally opened on 1 April 1872 by the Great Northern Railway on the original site of the Barnet Faire. It was the terminus of the branch of a line that ran from Finsbury Park to Edgware via Highgate. After the 1921 Railways Act created the "Big Four" railway companies the line was, from 1923, part of the London & North Eastern Railway. The section of the High Barnet branch north of East Finchley was incorporated into the London Underground network through the "Northern Heights" project begun in the late 1930s. High Barnet station was first served by Northern line trains on 14 April 1940 and, after a period where the station was served by both operators, LNER services ended in 1941. British Rail freight trains continued to serve the station's goods yard until 1 October 1962, when it was closed. The station still retains much of its original Victorian architectural character today, a considerable number of platform buildings dating from the pre-LT era. In the Autumn 2008, a new train crew accommodation block began construction immediately to the south west of the station in part of the station's car park. This accommodation was opened on 31 January 2010. Also further improvements have been introduced: A new covered step-free entrance from the car park to platform one is now available, along with a ramp at the end of the platform connecting it to platforms two and three. There are also two accessible toilets now available. These works were fully completed in October 2009. Therefore, there is full step-free access coverage in the station, although a considerably steep path to the station still exists if approaching from the north and a steep approach from the road to station level from the south also remains.
