The British Rail Class 390 Pendolino is a type of electric high-speed passenger train operated by Avanti West Coast in the United Kingdom, leased from Angel Trains.[4] They are electric multiple units using Fiat Ferroviaria's tilting train Pendolino technology and built by Alstom. Fifty-three units were originally built between 2001 and 2004 for operation on the West Coast Main Line (WCML). The 8-car units were all later lengthened to 9 cars, then an additional four trains and also a further 62 cars were built between 2009 and 2012. The trains of the original batch were the last to be assembled at Alstom's Washwood Heath plant, before its closure in 2005. The remaining trains in the fleet were built in Italy.

The Class 390 Pendolino is one of the fastest domestic electric multiple units operating in Britain, with a design speed of 140 mph (225 km/h); however, limitations to track signalling systems restrict the trains to a maximum speed of 125 mph (200 km/h) in service. In September 2006, the Pendolino set a new speed record, completing the 401 mi (645 km) length of the West Coast Main Line from Glasgow Central to London Euston in 3 hours, 55 minutes, beating the 4-hour-14-minute record for the southbound run previously set in 1981 by its ancestor, British Rail's Advanced Passenger Train (APT). The APT retains the ultimate speed record for this route, having completed the northbound journey between London Euston and Glasgow Central in 3 hours 52 minutes in 1984, which included a five-minute delay due to a signal fault.[8] The fleet is maintained at Longsight TMD near Manchester Piccadilly station.
