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 Abellio ScotRail on their Helensburgh/Milngavie/Balloch-Edinburgh via Bathgate and Dalmuir-Cumbernauld/Lanark/Larkhall routes. They were built for SPT/ScotRail (when part of National Express) 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, the 334s did not enter passenger service until 2001 due to numerous 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. The technical problems led to an extra two Class 170 and 2 additional Class 334 units being added as a goodwill gesture.
SPT purchased a total of 40 units 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.
In December 2010, the Class 334s operated the Ayrshire Coast Line, Inverclyde Line, North Clyde Line and Argyle Line.
