Proposal for HS4Air High Speed Rail Line between Gatwick and Heathrow

A new high speed rail line which would allow people to travel between Heathrow and Gatwick in just 15 minutes would see tunnels dug under the Surrey Hills and a train line built alongside the M25.

The proposal, named HS4Air, would cut through a large swathe of Surrey, running from just north of Heathrow to Gatwick and then east to Ashford in Kent.

There would be three sections of tunnel, running under part of Mole Valley, Gatwick, and under Staines and Heathrow.

The rest of the route would be overground and after leaving Gatwick travelling east, it would would cut across the A22 between Newchapel and Blindley Heath, past Lingfield to Edenbridge where it would head along the existing railway between Tonbridge and Ashford, to connect up with the forthcoming HS2 line.

Engineering firm Expedition and architects Weston Williamson have submitted the proposal in answer to a call for private sector projects by the Department for Transport (DfT).
