context_page_description: The Alstom Coradia Juniper series is a family of electric multiple unit trains built by Alstom Transport Birmingham for use on the railway network in Great Britain. The family is related to the Coradia 1000 series of diesel multiple unit.
  There are currently two types in service with various TOCs, with a total of 76 units in service. All Class 460s are now converted to Class 458/5s for South Western Railway.
context_section_description: The Class 458 is operated by South Western Railway on services from London Waterloo to Reading, Weybridge, Windsor & Eton Riverside, and circular metro routes from Waterloo via Richmond and Hounslow. As with all electrically powered trains on the former Southern Region, the Class 458 units are powered using third rail at 750 V DC current. Initially, a total of thirty 4-car units were built, with deliveries beginning in 1998, with the full complement in service by 2004. However, they suffered from leaky roofs and failing electronics and were therefore stored from 2004 to late 2005, being replaced by more Class 450 units on the routes they operated. For a brief period, they were subleased to Gatwick Express, but were never used on Gatwick Express Services.
  In 2013, former operator South West Trains and Porterbrook began the process of creating a new, 36-strong fleet of 5-car trains by reforming and partially rebuilding the vehicles from the Class 458 and Class 460 fleets; by creating 30 units utilising the original Class 458/0 vehicles, with an extra ex-Class 460 vehicle per unit to create 5-car units, and an additional 6 new 5-car units created entirely from ex-Class 460 stock. The new units have been  renumbered as the Class 458/5. They entered service in March 2014. Work included complete reconstruction of cabs and gangways, as well as changes to the passenger areas. The units are being repainted into the same livery as the Class 450 units (they previously were painted in the South West Trains Express livery carried by the Class 444, 158 and 159 units). This process was completed in 2016. The original 30 ex-Class 458/0 units are numbered 458501-458530, and are distinguishable from the ex-Class 460 stock (458531-458536) by noting the different ribbon-glazed windows on ex-Class 460 units, different door window sizes and the lack of a pantograph recess on ex-Class 460 units. This means that if future conversion to OHLE is required for this fleet, the process will be much simpler on 458501-458530 than 458531-458536.
  All units are now in South Western Railway - branded South West Trains livery, and are due to be replaced on all South Western Railway routes by new Class 701 units from 2019-2020.
