Making Connections

Heathrow International Airport Terminal 5 Intermodal Station
London, UK

The goal for the Heathrow’s Terminal 5 Intermodal Station was to provide “the best rail to air experience at any airport in the world” for its estimated 3 million annual passengers.

The station connects air passengers with trains, buses, high-speed rail and the Underground.

The station consists of six platforms: two for the London Underground Piccadilly Line extension, two for Heathrow Express and two for rail service expansion. Glass-walled elevators link the subterranean station to the top-floor departures level.

The concourse has the character of a mainline station. Travelers have a clear route from platform to check-in areas, with the link covered by a lightweight tensile fabric roof that allows daylight to permeate into the deepest level. The natural light helps the underground station feel more like an above-ground space.
