The British Rail Class 489 (or GLV) is a type of electrical multiple unit, specially converted for use on Gatwick Express trains, from London Victoria to Gatwick Airport.The units were converted from Class 414 driving motors cars, by Eastleigh works in 1983-84, for use on the new Gatwick Express service. They were used to allow push-pull operations, on the London-end of the rakes of Class 488 stock, with a Class 73 locomotive at the other end and both used for propulsion.
