British Rail Class 334

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 deliveries started to Strathclyde in 1999, the Class 334 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 upon their introduction.

SPT ordered 38 units, but the technical problems led to an additional two units being built as a goodwill gesture.

All units are owned by Eversholt Rail Group. ScotRail leased 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. The units initially ran on the Ayrshire and Inverclyde lines, but became a common sight on the Argyle and North Clyde lines.

From its introduction, the Class 334 operated on the Ayrshire Coast Line, Inverclyde Line, North Clyde Line and Argyle Line, but by June 2011 the class had been largely replaced on the Ayrshire and Inverclyde lines by the Class 380, with only occasional units seen on those routes.

In September 2008, the Scottish Government's agency Transport Scotland announced that all ScotRail trains (including those 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.[2][3]

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.[3][4][5] 334020 was the first unit to be refurbished at Kilmarnock's Brodie Rail Works from 3 February 2012 to 2 May 2012. The last unit to receive a refurbishment was 334006, which left Brodie Works on 8 November 2014.

• 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 when it collided with an empty, stationary Class 318. The train was travelling at less than 4 mph (6 km/h) 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.[6]
• On 15 October 2015, 334016 was involved in a collision on the approach to Uphall railway station. The unit was working the 16:39 Edinburgh to Milngavie service when it collided with an empty Toyota Hilux pick-up truck which had been stolen and abandoned on the tracks. The train was travelling at approximately 75 mph (121 km/h) when the collision occurred. The unit did not derail, but one passenger suffered minor injuries to their hand from broken glass. [7]
