Heathrow Connect is a train service in London that runs between Paddington station and Heathrow Airport. It is provided by the Heathrow Express company together with First Great Western and the first train ran on 12 June 2005.
The Heathrow Connect service runs every half-hour throughout the day and evening from Monday to Saturday and every hour on Sunday. It follows the same route as the Heathrow Express service, but while Heathrow Express runs non-stop between Paddington and the airport, Heathrow Connect stops at some stations in between. Altogether, there are eight stations at which Heathrow Connect trains stop, so the train can connect places in west London with each other, the airport, and Central London. The trains used on the line are five Class 360s made by Siemens.
In 2018, Heathrow Connect will be replaced by Crossrail and its Class 345 trains, and trains will run into new tunnels under Central London and on to places east of London as far as Shenfield in Essex.
