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, 3 and 4.
A total of six Elizabeth line trains per hour will serve Heathrow Terminals from December 2019. Four will go to Terminals 2, 3 and 4 and two will go to Terminals 2, 3 and 5. This will also increase services to Ealing Broadway, Southall and Hayes & Harlington.
When the service is fully operational in 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.
