Operator

The Class first entered service on 19 January 1998 when services commenced from London Paddington to Heathrow Junction. They operated through to Terminal 4 from May 1998 until March 2008, when the Heathrow Express was diverted to serve Terminal 5. The original order was for twelve three-car and two four-car sets. The twelve three-carriage sets were increased to four-car sets by the end of 1998. In 2002, five sets had a fifth car added.


2016 recall

On 29 February 2016, the entire class was withdrawn after a structural defect was found on the underside of a driving car of unit number 332014. They were replaced by
