The station was opened on 23 June 1998 upon the completion of the Heathrow Express Rail Link linking Heathrow Airport with direct non-stop services to Central London. In contrast to the stations Terminals 4 and 5, the platforms at Heathrow Central do not lie  adjacent to the London Underground Piccadilly line platforms at Heathrow Terminals 2 & 3 station. Instead they lie perpendicular, and at a far deeper level. The reasoning behind this is because the Heathrow Express line was tunnelled into Heathrow from the north, whereas the Piccadilly line approaches from the east. Access to the station is reached via an underground pedestrian walkway which links Terminal 3 to the Central Bus Station and the Piccadilly line's Heathrow Terminals 2 & 3 station. Since May 2018, the station has been served by TfL Rail, part of the new Crossrail project, replacing the Heathrow Connect  service. Services initially run as far as London Paddington calling at all intermediate stations. Towards Paddington, TfL Rail services operate along the Eastern end of the Great Western Main Line calling at Hayes & Harlington, Southall, Hanwell, West Ealing where it connects with the Greenford branch, Ealing Broadway, Acton Main Line and finally London Paddington where it connects with all National Rail services on GWR and the London Underground network.
