On the Central line, it is between Perivale and Northolt stations while on National Rail, the next station to the south on the branch is . Greenford station is in Travelcard Zone 4. The original Greenford station was opened by the Great Western Railway on 1 October 1904 on the joint "New North Main Line" (present-day Acton–Northolt line). The present station, adjacent to the original, was designed by Brian Lewis and built in the Central line extension of the 1935-40 New Works Programme of the London Passenger Transport Board. It was completed by Frederick Francis Charles Curtis and opened on 30 June 1947 after delay due to World War II. Service at the original ("main-line") station was gradually reduced and it was closed in 1963. Operational responsibility for the station transferred from British Rail to London Transport with effect from 13 November 1967. The site of the old station for the New North Main Line can still be seen from inside Central line trains. Greenford station is above ground level with an island platform for the Central line. A bay platform facing south-east between the Underground platforms serves the Greenford branch service operated by Great Western Railway. The branch line then continues south and joins the Great Western Main Line at . Platform 1 is for westbound Central line trains, and platform 3 for eastbound trains. The access to the platform via escalators takes passengers to the front of the train for westbound service, and the rear for eastbound service. Greenford was the first London Underground station to have an escalator up to platforms above street level. Until 2014 it remained the final London Underground station with a wooden-treaded escalator in service; all other such escalators were previously converted to fully metal treads, or removed altogether from sub-surface Underground stations in the wake of the fatal 1987 King's Cross fire.
