Western Rail Approach to Heathrow
The Western Rail Approach to Heathrow is a proposed rail link in Berkshire, England, which would create an additional connection between London's Heathrow Airport and the Great Western Main Line. Beginning at Heathrow Terminal 5 station, the link would run via a tunnel to a junction east of Langley station, allowing trains to run westwards towards Reading and Slough. When completed, the link would improve rail connections to Heathrow from the Thames Valley as well as from South-West England and South Wales. It would also reduce congestion at London Paddington station by removing the need for Heathrow passengers on this route to travel into central London.

The project was announced by the Department of Transport in July 2012. Theresa Villiers, the rail minister at the time, included the project in the High Level Output Statement published in 2012. This stated 'The Government wishes to see a new railway link to give western rail access to Heathrow Airport' but did not commit to the scheme, making it 'subject to a satisfactory business case and the agreement of acceptable terms with the Heathrow aviation industry'.
Network Rail originally estimated that the project could be operational by 2020. In January 2017, Network Rail's estimate was 2024. Slough Borough Council has cited 'parliamentary activity' as the reason for the delay but not offered further explanation.
In May 2018, it was reported that Network Rail intended to apply for a Development Consent Order in 2019, and that construction of the railway link would be privately financed.
The currently proposed route is a new 5.5 kilometres (3.4 miles) railway line that would leave the Great Western Main Line between Langley and Iver before entering a new tunnel. The tunnel (composed of two smaller tunnels) would pass under Richings Park and Colnbrook and then join existing rail lines at Heathrow Terminal 5.
Four access buildings will be built along the route to provide emergency access to the tunnels, with two additionally providing ventilation.
Realignment of the existing tracks will also be required between Langley and Iver.
The Western Rail Approach is, according to the Aircraft Expansion Consultation, designed to be "independent yet compatible" with the Heathrow expansion.
It is envisaged that there would be a service of four trains an hour from Heathrow to Slough and Reading. Earlier publicity also suggested there would be two trains per hour to Twyford and Maidenhead.
Alternative & complementary schemesEdit
Another alternative scheme is the Windsor Link Railway, which would provide both western and southern access to Heathrow.
A complementary scheme which could be developed at a later date, or alongside the Western Rail Approach, is the Heathrow Southern Railway, which envisages links from the airport to the south and south west.
