Heathrow Express
The station opened on 23 June 1998, together with the Heathrow Express. From 1998 to 2008, the station was the terminus of the Heathrow Express service from London Paddington. All services terminated here after calling at Heathrow Central. In 2005, the Heathrow Connect service was introduced, which provided a slower service to Paddington but calling at local stations along the way, as well as offering cheaper fares. This service also terminated at Terminal 4, together with the Heathrow Express. Upon the opening of the new Heathrow Terminal 5 station in 2008, all Heathrow Express services were re-routed to terminate there, and services to Terminal 4 were replaced with an every 15 minute shuttle service, which ran between Heathrow Central and Terminal 4. Most Heathrow Connect services then terminated at Heathrow Central, although on Sundays, they continued to Terminal 4.
