Engineering work is taking place between London Paddington and Ealing Broadway, closing all lines for 5 days.
As a result, no Heathrow Express trains will run between London Paddington and Heathrow Terminals 2&3 in either direction.
Shuttle trains will only run between Heathrow Terminals 2&3 and Heathrow Terminal 5 every 20 minutes from 05:20 until 23:30.
