The article discusses the extension of the London transport underground to Heathrow airport and how it operates within the existing underground services. One of the main benefits of the underground extension has been to reduce road congestion in the approach roads to the airport by carrying an expected 30% of air travellers. The Piccadilly Line, of which the extension forms a part, operates fifteen trains per hour at peak periods. The 3.5 ml extension from Hounslow West was constructed by cut and cover methods to the airport and then by deep level tube tunnels under the runways to the centre of the airport. It is at this location that Heathrow Central station has been built in a reinforced concrete construction 400 ft long and 75 ft wide. The ticket hall is connected with each of the three air terminals by wide subways equipped with moving walkways in both directions. It is thought that early misgivings concerning the possibility of conflict between air passengers and other users of the Piccadilly Line are unlikely to be justified even with further traffic growth.
