  • Improving rail links to Heathrow

    A new direct rail link connecting the west to Heathrow will improve journeys to the UK’s busiest airport and help increase economic productivity across the Thames valley

  • Hero
  • As part of our Railway Upgrade Plan we are developing plans to build a new rail tunnel to link the Great Western Main Line to London Heathrow Terminal 5. The proposed rail connection will speed up journeys to the UK’s busiest international airport, by allowing passengers to travel to the airport from Reading, Twyford, Maidenhead and Slough without going into London Paddington.


  • For passengers

    • Reduce rail journey times between Reading and Heathrow (by approximately 35 minutes)
    • Direct trains between Reading, Slough and Heathrow (approximate journey time from Reading will be 26 minutes)
    • Improved access to Heathrow from the South Coast, South West, South Wales and West Midlands
    • More travel options for leisure and business travellers as well as Heathrow employees to London Heathrow
    • Reduced congestion at London Paddington 

    Wider benefits

    • Over £800 million of UK economic activity, including additional economic benefits for the region
    • Create potential for 42,000 new jobs
    • Make CO2 savings equating to approximately 30 million road miles a year
    • Give 20 per cent of the UK population access to Heathrow via one interchange
    • Help to provide much needed congestion relief for the M4, M25 and M3 (55% of journeys on the proposed service will be abstracted from the road)
  • Public consultation update

    Thank you to everyone who has taken the time to provide us with feedback throughout this formal stage of consultation for the proposed rail link to Heathrow. The consultation deadline for this phase has now closed.

    Our consultation and project team will now compile the feedback that has been submitted during consultation, and present this via a consultation feedback newsletter that will be available on this webpage soon.

    The statutory phase of consultation is planned for early 2017, where we will be able to share the details surrounding the design updates, which will have been informed by the formal phase of consultation. At the next phase, we will be presenting our final design, ahead of the Development Consent Order submission, which is planned for later in 2017.

    If you would like to review the information and documents that were available during consultation, you can still access these on the consultation hub.

    In the meantime, if you have any further comments or questions about the plans, you can send us an email at:
