Question to the Department for Transport:

To ask the Secretary of State for Transport, whether the Civil Aviation Authority has undertaken any recent work with (a) her Department, (b) Heathrow Airport, (c) Network Rail and (d) others to make progress on the construction of a Western Rail Link to Heathrow.

Since plans for expansion were paused in 2020, the CAA has not conducted any work in relation to a Western Rail link to Heathrow. Should any such plans emerge as part of fresh proposals for Heathrow expansion, the CAA would review the elements of those plans relevant to its role as economic regulator of Heathrow in accordance with its statutory duties.
