Heathrow Terminal 5 station

Heathrow Terminal 5 station is a shared railway station at London Heathrow Airport Terminal 5 which was opened on 27 March 2008. It was designed by architects HOK International in conjunction with Rogers, Stirk, Harbour & Partners.

The station is staffed by Heathrow Express staff unlike the underground stations at Heathrow Terminal 4 and Heathrow Terminals 1, 2, 3. The station is situated in Travelcard Zone 6. It is the westernmost below-ground station on the London Underground network.

Although situated underground, parts of its roofing are made of translucent ETFE laminate panels, allowing natural daylight to flood down both ends of all six platforms.

The Terminal 5 station is served by the following rail services :
 * Piccadilly Line: half the trains on the Heathrow branch terminate here, via Hatton Cross and Heathrow Terminals 1, 2, 3. The other half run via Hatton Cross, Heathrow Terminal 4 and Heathrow Terminals 1, 2, 3, and back to Hatton Cross.
 * Heathrow Express: terminates here. This service replaced the Express service to Terminal 4, which instead became the terminus for Heathrow Connect.

Future links
In addition to the above rail links, the T5 Rail Station also has two safeguarded "heavy rail" platforms for use by a west-facing connection to the National Rail network. This proposed link starting from near the existing Staines railway station is called Heathrow Airtrack and would offer half-hourly services to London Waterloo, Reading, Woking and Guildford. BAA have published as part of the Airtrack consultation that they also want to extend the Heathrow Express to a new platform at Staines railway station. The plans originally included the rebuilding of Staines High Street railway station but, due to local opposition and passenger projections, the station has been dropped.

Transport links
London bus routes 350, 423, 482, 490 and night route N9.
