British Rail Class 334

The British Rail Class 334 Coradia Juniper is a suburban electric multiple unit passenger train built by Alstom in Birmingham, part of the Coradia Juniper family along with Classes 458 and 460. The trains are operated by ScotRail and mainly run on the North Clyde Line between Helensburgh Central and Edinburgh, Springburn to Milngavie and Airdrie to Balloch, and sometimes on the Argyle Line. They were ordered by SPT and ScotRail, then part of National Express, for outer-suburban services in Glasgow, and their introduction saw the withdrawal of the last of Glasgow's Class 303 Blue Train sets, which had been in service since 1960. Deliveries to Strathclyde started in 1999, but the Class 334 did not enter passenger service until 2001 because of numerous teething problems and technical failures. All units are owned by Eversholt Rail Group and ScotRail leased a total of 40. Relivery in blue with white Saltire markings began in November 2010, and from early 2015 Eversholt commissioned Alstom to perform a 36.1 million pound overhaul adding air conditioning, at-seat charging points, provision for wi-fi, LED lighting and CCTV.
