Heathrow Express is operating a reduced service and TfL Elizabeth line is currently experiencing disruption due to a power issue affecting the rail network between Paddington and Maidenhead.
London Underground services are operating as normal, and a replacement bus service is running between Terminal 4 and Terminals 2&3. Passengers travelling between Terminal 2, 3 and 5 can continue to use the Piccadilly line, which is operating as usual.
We apologise for any inconvenience.
