Heathrow Southern Railway (HSR) is a privately financed proposal for a Southern Rail Link to Heathrow Airport (SRLtH). HSR is an important project that would help resolve the long term problem of rail inaccessibility to the Airport from the south, specifically from Surrey and South West London. The scheme entails 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.

The 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.

Alongside the Heathrow Express, the Piccadilly line and from 2019, the Elizabeth line, HSR will create new routes from the south into central London for airport passengers and commuters providing an enormous increase in rail connectivity. In addition, it will ensure that the current level of road travel from the airport does not increase and will contribute to improving local air quality. All things being equal, the new rail link will be open to passengers between 2025 and 2027. The proposed construction planned will endeavour to minimise the impact on neighbouring communities by providing a route mainly in tunnel, mainly avoiding level crossings in the Egham area.
