Transforming access to Heathrow from the south

Heathrow Southern Rail is a privately funded proposal for Southern rail access to Heathrow Airport.

Heathrow Southern Railway (HSR) is all about allowing fast, easy and relaxing access to Heathrow Airport through the construction of up to 8 miles of new railway from the west end of the existing Terminal 5 station, linking the south western and great western rail corridors.

HSR would open up access to and through Heathrow from the South West and South East by enabling trains to operate between Heathrow and Waterloo via Clapham Junction, Putney, Hounslow, Twickenham, Richmond, Staines and other intermediate stations; and Heathrow and Woking, Guildford and Basingstoke. Trains could set out on these journeys from as far away as the south coast.

Our new railway will also improve connectivity between Surrey and London for commuters, creating a new route from Basingstoke, Guildford and Woking, via Heathrow Airport, to Old Oak Common (for HS2 and the Elizabeth Line) and London Paddington.

Whether or not a third runway is built, many more passengers and airport workers need to be accessing Heathrow by train. The Government’s recent M25 South West Quadrant Study ruled out widening the motorway.

HSR provides the alternative, switching traffic from the roads and contributing to improving local air quality. We estimate that HSR will reduce road use around Heathrow by over three million car trips a year around half of which are removed from the busiest section of the M25.

Appraised under the Department for Transport’s formula, HSR has a High value for money rating if the airport is expanded, and a Medium value for money rating with Heathrow’s current passenger numbers and two runways. HSR will be financed privately and can operate at no cost to taxpayers and could open by 2025.

Our construction plans minimise the impact on neighbouring communities by providing a route mainly in tunnel. Unlike the previous “Airtrack” proposals, HSR avoids level crossings in the Egham area.
Through this website we introduce our project. Further information will be posted as the plans for HSR are developed. We welcome enquiries from residents, communities, elected representatives, media, businesses and other stakeholders. Please go to our contact page if you would like to get in touch.
