The British Rail Class 334 is a suburban electric multiple-unit train built by Alstom in Birmingham. They are part of the Juniper family of trains along with Classes 458 and 460. The trains are operated by First ScotRail on its Helensburgh/Milgavie/Balloch-Edinburgh via Bathgate and Dalmuir-Springburn/Lanark/Larkhall routes. They were built for SPT/ScotRail (when part of National Express Group) outer-suburban services in Glasgow.
Their introduction saw the withdrawal of the last of Glasgow's venerable Class 303 "Blue Train" sets which had been in service since 1960. Although delivered to Strathclyde in 1999-2002, they did not enter passenger service until 2001 due to a large number of teething problems (in common with other Juniper-based classes) and technical failures which plagued the new units at their introduction. SPT had ordered 38 Juniper units originally, but two were added to the order as a goodwill gesture due to teething problems.Template:Citation needed
SPT purchased a total of 40 units, although only paying for 38 of the units (2 were given free, with the reason stated above) which can be seen in use daily across the SPT electric network. On the maiden run of the units, 334010 and 334020 ran to Gourock. Initially the units ran Ayrshire Coast Line and Inverclyde Line but then become a common sight on the Argyle Line and North Clyde Line.
Relivery and RefurbishmentEdit
In September 2008, the Scottish Government's agency Transport Scotland announced that all ScotRail trains (including from the Strathclyde Partnership for Transport) would be eventually repainted in a new, blue livery with white Saltire markings on the carriage ends. Class 334 re-livery began in November 2010 in preparation for the Airdrie to Bathgate reopening. 
On 24 August 2011, ScotRail announced plans to refurbish all the fleet, with the project expected to start in November 2011 and take two years to complete. 334020 was the first to be properly refurbished at Kilmarnock's Brodie Rail Works. It was there for 3 months from 3 February 2012 to 2 May 2012.
On 16 January 2008, 334017 was involved in a minor collision whilst entering Glasgow Central station. The unit was working the 08:24 Gourock to Glasgow Central service (2G16) when it collided with an empty, stationary Class 318 unit (318267). The train was travelling at less than Template:Convert when the collision occurred. Four passengers were slightly injured; however only one required hospital attention, and was transferred to Glasgow Southern General hospital in a taxi. The unit was undamaged.
