The Class 150 Sprinter was designed to revitalise the DMU fleet and remains in service today mainly in the South West and North of England and Wales. The Class 150 had a rival in the Metro-Cammell built Class 151 [2] (and indeed made use of some work Metro-Cammell had already done on next generation DMUs) but following an extensive series of tests the 150 proved to be the more popular with BR (the fact the 151 was late didn't help matters), series production was given the go-ahead [3]. One of the 150 prototypes was fitted with the transmission from the 151 for tests, this was re-designated the Class 154 [4] though it has now been reverted to a standard 150.

The Class 150 was built in either two or three car sets, most 150s in service these days apart from the prototypes are two car though for a time some 150/1s were in three car formations [5].
The original 150/0 prototypes remain in service, the main difference with serial production 150s is that they have smaller fuel tanks and that they are three car sets. The initial series production version was the 150/1 with the 150/2 having front-end gangways. There was also for a time a small 150/9 sub-class in service with GWR which were hybrid 3-car sets with a driving car as the centre car. The Class 150 is currently in service with GWR, Transport for Wales and Northern.
An extra two-car set was built for British Rail as the Class 950 Track Recording Unit which apart from body modifications for various test equipment is mechanically the same as the rest of the Class 150 fleet.
