The Elizabeth line will significantly improve links between Heathrow and a number of central London destinations, including the West End, the City and Canary Wharf.
The new Elizabeth line service will replace Heathrow Connect trains. Heathrow Express will continue to provide a non-stop service between Heathrow and Paddington.
From May 2018, four trains an hour will run between Paddington and Heathrow terminals 2 to 4.
From December 2019, Elizabeth line trains will run from the airport through the new tunnels, providing a direct link to central London destinations including Bond Street, Liverpool Street and Canary Wharf.
