 Waterloo station was to be the central London terminus for the proposed Heathrow Airtrack rail service.This project, promoted by British Airport Authority Limited (BAA), envisaged the construction of a spur, from on the Waterloo to Reading line, to Heathrow Airport, creating direct rail links from the airport to Waterloo, and Guildford.Airtrack was planned to open in 2015, but was abandoned by BAA during 2011.
