Heathrow Terminal 4 is aLondon Underground station atHeathrow Airport on the Heathrow branch of thePiccadilly line. The next stations areHatton Cross to the east andHeathrow Terminals 2 & 3 in a one-way operation at the airport. The station is located inLondon fare zone 6.
In 1979, approval for afourth terminal at Heathrow Airport was granted. An extension of the Piccadilly line to serve the new terminal was agreed in October 1981.[7] Thestation box would be built by theBritish Airports Authority as part of the £200 million construction cost of the new terminal. By 1982, construction of the fourth terminal building was behind schedule, and in July 1982 the location of the station was moved from below the terminal building to a nearby car park.
Construction began in February 1983.[8]London Regional Transport funded the construction of 2.5 mi (4.0 km) of new tunnels, the track and the fit-out of the station, at a cost of £23 million. Construction was completed by November 1985.[8] It was built byBalfour Beatty, and the ticket hall.[9]
The station was officially opened by thePrince andPrincess of Wales on 1 April 1986, before opening the Terminal 4 itself shortly afterwards.[10] Trains, however, did not stop at the station until 12 April, when the new terminal started to handle flights.[11]
The station is situated on a unidirectional loop tunnel which was constructed between the existingHatton Cross andHeathrow Terminals 2 & 3 stations. The station is one of four on the London Underground with only one platform, and is the only one with one-way train service. It is adjacent toHeathrow Terminal 4 railway station used byElizabeth line services that travel through the newer mainline tunnel.
In-service routing took trains from Hatton Cross to Terminal 4 then Terminals 2 & 3 and back to Hatton Cross. On 7 January 2005, both the loop track and the station were closed temporarily in order to allow the construction of a new rail junction to link to the newHeathrow Terminal 5 station. All trains reverted to using the original westbound track from Hatton Cross direct to Heathrow Terminals 2 & 3 which was used prior to the opening of Heathrow Terminal 4. For passengers travelling to or from Heathrow Terminal 4, a shuttle bus was provided from Hatton Cross tube station. This situation continued until 17 September 2006 when the loop line and station were reopened after construction finished, with new security and customer announcement technologies in place at the station.[12]
Heathrow Terminal 4 tube station is located on a unidirectionalclockwise loop that branches off after Hatton Cross westbound, and rejoins the Heathrow branch eastbound to the west of Heathrow Terminals 2 & 3.
Since the opening ofHeathrow Terminal 5 station, alternate Heathrow branch trains run via the Terminal 4 loop, with the other alternate trains run directly to Heathrow Terminals 2 & 3, and Heathrow Terminal 5.
Until 2012, free transfer was not possible between terminals, in contrast to theHeathrow Express. In January 2012, free travel was introduced forOyster card holders between the three Heathrow stations. But to travel from Heathrow Terminals 2 & 3 or Terminal 5 to Terminal 4 one must change trains at Hatton Cross. This journey is free with Hatton Cross itself being part of the free travel zone.
On 9 May 2020, Heathrow Terminal 4 station closed temporarily until 14 June 2022, due to the closure of the airport's Terminal 4 during theCOVID-19 pandemic in London.[13]
On 14 June 2022, this station reopened for passenger service.
TwoLondon Buses routes serve the station:482 and490.
