North Acton is a London Underground station in North Acton, west London in the London Borough of Ealing. The station is on the Central line between East Acton and Hanger Lane on the West Ruislip Branch and West Acton on the Ealing Broadway Branch. It is on the boundary of Travelcard Zone 2 and Zone 3. History The joint "New North Main Line" (NNML; the present day Acton–Northolt line) of the Great Central and Great Western opened in 1903 and its North Acton Halt railway station followed in 1904, though it was closed by 1913. The Great Western Railway (GWR) built the Ealing & Shepherd's Bush Railway, which connected the Central London Railway (CLR) with the GWR's Ealing Broadway station. CLR trains began using the route on 3 August 1920. The stations at North Acton and were built and owned by the GWR, and both opened on 5 November 1923, the new North Acton being a short distance east of the 1904 halt. As Transport for London explains: North of the Central line tracks were two freight lines, removed in the 1960s, running alongside the Central line as far as White City; to the north of those at a slightly higher level were the two tracks of the NNML. The NNML platforms closed when the Central line was extended on new track from North Acton to Greenford station in 1947. Today, only the outer-most NNML platform remains partially intact, having been removed in the early 1950s. Between South Ruislip station and Old Oak Junction, the GWR line was progressively run down, and in many places it is now single-track, including the stretch running past North Acton, which was reduced to single-track in 1993. From May 2008 until December 2018 only freight trains and a once-daily passenger service provided by Chiltern Railways used this stretch of line. The Underground station had only two platforms until 1992, whereby for operational flexibility an island platform was created by building a third platform north of the other two, where the old freight line track bed had been. The third platform became the eastbound road while the eastbound platform (now the middle platform) was resignalled to allow it to be used also for terminating and starting services. This change allows shuttle services to be run to White City from Ealing Broadway and from West Ruislip in the event of problems elsewhere on the Central line,
