British company Expedition Engineering, together with architects Weston Williamson + Partners (WW+P) and planning and development consultants Turley, will submit their plans on high-speed rail development to the UK Department for Transport in response to a call for ideas within the rail sector.
The “HS4Air” is a proposal for a new high-speed railway around London that passes via both Gatwick and Heathrow Airports. The new railway line, estimated at £10 billion (EUR 11.2 billion), will connect HS1 at Ashford to HS2 North West of London via Heathrow and Gatwick airports with a spur connection to the Great Western Main Line.
HS4Air would allow train journey times to be slashed from the UK’s two most important airports together with their hinterlands in South East England to the Midlands, North England and South Wales.
According to the proposal, four new stations along HS4Air at Ashford, Tonbridge, Gatwick and Heathrow will provide important new points of new transport connectivity to the rest of the UK beyond London. Both Heathrow and Gatwick airports will become multi-modal regional transport hubs with many passengers using these stations even if they are not catching a plane.
HS4Air will provide a fast “bypass” rail route around London and fast direct passenger and freight trains from the Midlands and North England to Europe.
