The Coradia Juniper series is a family of electric multiple unit trains built by Alstom Transport Birmingham, subcontractor: Ganz Hunslet, Hungary, 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 (36 class 458s and 40 class 334s). All Class 460s are now converted to Class 458/5s for South West Trains.
The Class 334 is an EMU in service with Abellio ScotRail on the suburban network around Glasgow, including services to Edinburgh Waverley via Airdrie and Bathgate on the North Clyde Line. Class 334 trains are powered using overhead wires at 25 kV AC. A total of 40 three car units are in use (numbered 001-040), of which 38 were delivered from Alstom trains in 1999, although due to teething problems, two extra were ordered and they did not enter service until 2001.
The Class 458 (also known as 4Jop) is operated by South West Trains on services from London Waterloo to Reading, and Ascot to Guildford. 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. 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.
South West Trains and Porterbrook are in 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. The new units have been renumbered as the Class 458/5. They entered service in March 2014. Work includes 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).
The Class 460 electric multiple units (also known as 8Gat) were originally built for use on the dedicated Gatwick Express airport service to London Victoria. The units were delivered between 2000 and 2001 and like the similar Class 458 they are powered using 750 V DC current on the third rail. The fleet consists of 8 units in total numbered 460001-008, each formed of 8 vehicles (driving motor luggage van, two intermediate 1st-class/composite trailers, two intermediate 2nd-class motor carriages, an intermediate 2nd-class trailer, another 2nd-class motor carriage, and a 2nd-class driving motor).
Following their removal from the Gatwick Express franchise in September 2012 a decision was made to reform and merge the Class 460s with the Class 458 vehicles in order to form 36 x 5-car trains to boost capacity on the South West Trains network. The first two of the 5-car sets were delivered in October 2013, and are undergoing testing ahead of the introduction of the first 10-car train into service in December 2013. Passenger service had started in March 2014.
