A £375m light-rail link to Heathrow airport is one of a number of third-party proposals submitted to the Department for Transport.The scheme, similar in style to the Docklands Light Railway, has been submitted by Spelthorne Council and is an alternative to bids by the Windsor Link Railway and Heathrow Southern Rail, reports New Civil Engineer.It would link a new station in Staines to the airport, which the council claims would release “huge untapped potential” for Heathrow.
