Description
The Heathrow Express Link provides a 15 minute high speed rail service between Paddington Station and Heathrow Airport. A 7.25 km spur running for the most part in tunnel provides the airport with underground stations at the Central Terminal area (Terminals 1, 2 & 3) and Terminal 4. Provision was also made for a link to the at this point proposed Terminal 5. The 5.5 km long tunnelled section will pass under the M4 motorway with the portal located to the north.
