Heathrow Connect Trains
Heathrow Connect was an operating company jointly run by Heathrow Express and Great Western Railway until May 2018. The service ran between Heathrow Airport and London Paddington, the same route as the Heathrow Express but included several West London stations en route.
Transport for London took over the services with a view to incorporate them into a new Elizabeth Line, due to be launched in 2021.

If you’re looking to travel abroad, Heathrow Airport is a great location to fly from. While the Heathrow Connect services have now ceased to operate, the Heathrow Express offers a direct route to the airport from London Paddington.
The Heathrow Express does not include intermediate stations in West London, these will be on offer as part of the new Elizabeth Line.
