From Sunday 20 May TfL will take over the Heathrow Connect services between Paddington and Heathrow terminals 2/3 and 4 in another major milestone in the creation of the Elizabeth line.
From Monday 21 May it will also take over the half hourly Great Western Railway (GWR) services from Paddington which terminate at Hayes & Harlington.
These services will be operated as TfL Rail, which will become Elizabeth line services in December this year when the line opens through central London, transforming travel with quicker, easier and more accessible journeys for customers.
The new railway, jointly sponsored by the Department for Transport and TfL with support from London’s business community, will connect stations such as Paddington to Canary Wharf in only 17 minutes, transforming how Londoners and visitors move across the capital.
Under TfL Rail, the current service frequency of two trains an hour between Paddington and Heathrow will be maintained using the existing trains, alongside two trains an hour between Paddington and Hayes & Harlington using new Elizabeth line trains, which replace part of the Great Western inner suburban route.
Testing continues to enable TfL to introduce the new, spacious, air-conditioned Elizabeth line trains on services to the airport.
