The station is served by the Heathrow Express 'shuttle' service providing a train every 15 minutes between Terminal 4 and Heathrow Central. Some early morning, late evening and most Sunday services are operated by Heathrow Connect. Heathrow Express operate the station and tickets are sold for both Heathrow Express and Heathrow Connect services. Heathrow Express customers must first catch either a Heathrow Connect or shuttle service to Heathrow Central for access to Heathrow Express.
Heathrow Express previously operated services from Terminal 4 railway station to London Paddington. When Heathrow Terminal 5 opened on 27 March 2008, Heathrow Express terminated services to Terminal 4; their trains now run directly to Heathrow Terminal 5 instead. Up until 22 May 2010, Heathrow Connect operated all services from Terminal 4.
