BR Class 150

The British Rail Class 150 Sprinter is a class of diesel multiple-unit trains built by BREL York from 1984 to 1987. A total of 137 units were produced in three main subclasses, replacing many of the earlier, first-generation "Heritage" DMUs.

The 150s are still operated by Great Western Railway, Northern, West Midlands Trains and Transport for Wales.

Class 154
150002 proved to be the worse of the two for reliability and was consequently chosen for use as the testbed for the Class 158, being re-geared to a maximum speed of 90 mph (140 km/h) and fitted with Cummins engines and Voith transmission, and with a Class 158 interior. One car was fitted with the Class 151 Twin Disc 'hot-shift' transmission, which it used successfully once the control software was sorted out. To distinguish this unit, it was reclassified as the Class 154. It has since been returned to the standard configuration and reverted to its original number. Both prototypes were still in service with London Midland until 2011. 150001 entered service with First Great Western in January 2012, with 150002 to follow after refurbishment and re-livery. They are now used primarily on the Reading-Basingstoke line, with both 150001 & 150002 in the new Great Western Railway green livery.
