The British Rail Class 458 Juniper (5-JUP) is a class of electric multiple-unit passenger trains of the Alstom Coradia Juniper family, built at Washwood Heath between 1998 and 2002 for South West Trains.[7] The order for the original fleet of 30 four-car trains was placed in 1997, and delivery of the first unit followed in October 1998.[8] The fleet entered passenger service between 2000 and 2003 and is maintained at Bournemouth depot.[3][9]
Between 2013 and 2016, the class was merged with the mechanically similar Class 460 fleet and extensively rebuilt to form a fleet of 36 five-car units—designated Class 458/5—to provide an increase in capacity on services into London Waterloo.[10] The trains are now used by South Western Railway.[11]
In March 2021, South Western Railway announced that 28 Class 458 units would be refurbished for use on long-distance services on the Portsmouth Direct line, as a result of the company deciding to abandon its original plan to use upgraded Class 442 units for this purpose.[12] By 2024, this plan had been dropped, and the refurbished units were instead deployed on limited services out of London Waterloo from 24 June 2024.
