[5] From 1998 to 2008, the station was the terminus of the Heathrow Express service from London Paddington.

On 20 May 2018, TfL Rail took over the Heathrow Connect service in readiness for becoming part of the Elizabeth line, which at the time was expected to open in December 2018.

All services at Heathrow Terminal 4 are operated by the Elizabeth line using Class 345 EMUs.

The typical service is four trains per hour to and from Abbey Wood.

A small number of early morning and late evening services run only as far as London Paddington.
