North Ealing station was opened on 23 June 1903 by the
District Railway (DR, now the
District line) on its new extension from north of Ealing Common to
Park Royal & Twyford Abbey (closed and replaced by
Park Royal in 1931), where the
Royal Agricultural Society's
Park Royal show grounds had been recently opened. The line was opened fully to
South Harrow on 28 June 1903. This new extension was, together with the existing tracks between Ealing Common and
Acton Town, the first section of the Underground's surface lines to be
electrified and operate
electric instead of
steam trains. The deep-level tube lines open at that time (
City & South London Railway,
Waterloo & City Railway and
Central London Railway) had been electrically powered from the start. North Ealing was the only station on the South Harrow branch not rebuilt in the 1930s to the "Holden" style for the start of the Piccadilly Line service. As a result, it retains its slightly rural air. A 1930s railway sub-station is built alongside the Eastbound platform and is typical of the LPTB brick and concrete architectural style of the period. On 4 July 1932 the Piccadilly line was extended to run west of its original terminus at
Hammersmith sharing the route with the District line to Ealing Common. From Ealing Common to South Harrow, the District line was replaced by the Piccadilly line and, from this date, District line trains west from Ealing Common ran to Ealing Broadway only. In 2018, it was announced that the station would gain step free access by 2022, as part of a £200M investment to increase the number of accessible stations on the Tube. ==Services==
