An innovative, privately financed new railway expanding train connections across London and southern England
Heathrow Southern Railway (HSR) is a privately financed proposal for a Southern Rail Link to Heathrow Airport (SRLtH).
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 of England by enabling trains to operate between Heathrow and Waterloo via Clapham Junction, Putney, Hounslow, Twickenham, Richmond, Staines and other intermediate stations; and between Heathrow, Woking, Guildford, Farnborough and Basingstoke. Trains could set out on journeys to Heathrow 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 each year HSR will reduce the number of road journeys by around 3 million and avoid the release of 2 tons of NOx and 8,600 tons of CO2 into the atmosphere.
Crucially, many of the road journeys removed would otherwise use the M25 which, adjoining Heathrow, is the busiest motorway in Europe and contributes to the current illegally poor levels of air quality around the Airport.
HSR will be financed privately and can operate at no cost to taxpayers. With a quick start, our new railway could open by the end of 2026, coincident with the third runway.
Although HSR can be built and operated without the need for taxpayers’ money, it does need Government action in two other ways. Firstly, by running a process to identify a Preferred Developer for the SRLtH and, secondly, by giving an assurance that once the new railway is built it will specify that trains must use it. Such a guarantee will unlock low cost capital and obviate the need for premium fares or subsidies. We are awaiting the Government describing the outcomes it wants to see and the process it will run for maximising private sector involvement in the SRLtH.
Our construction plans minimise the impact on neighbouring communities by providing a route mainly in tunnel and using only electric trains. 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.
