Heathrow Connect is a train service in London provided jointly by Heathrow Express and Great Western Railway (GWR), connecting Heathrow Airport with Paddington. The service follows the same route as the non-stop Heathrow Express service but calls at certain intermediate stations, connecting several locations in west London with each other, the airport, and Central London. It runs every half-hour throughout the day and evening. The service launched on 12 June 2005 and will be replaced by Crossrail in December 2019.
