Question to the Department for Transport:

To ask Her Majesty's Government what is the estimated cost of the Western Rail Link to Heathrow; and how much of that cost will be contributed by Heathrow Airport.

The total nominal capital cost for the Western Rail Link to Heathrow, in 2018 prices, is estimated at around £1.5bn to construct the rail link between Heathrow Airport Station and the Great Western Main Line. For the scheme to proceed, the Government has been clear that Heathrow Airport Limited would need to secure and provide an acceptable financial contribution.
