Overview
- A defective section of track near Hayes & Harlington has triggered a speed restriction that reduces the number of trains able to run.
- Services between Reading or Heathrow Terminal 5 and London Paddington are being cancelled, delayed or revised, with some trains starting or terminating at intermediate stations.
- Passengers can use tickets at no extra cost on Great Western Railway between Reading and Paddington, on local buses between West Drayton and Paddington, and on the London Underground by reasonable routes.
- Transport for London says engineers are working with Network Rail to fix the fault, and disruption is expected to continue through the day with no firm restoration time given.
- Heathrow Express is operating a half-hourly service despite the restriction, and customers are urged to check for last‑minute changes and platform alterations.
