British Rail Class 150

The British Rail Class 150 Sprinter is a class of diesel-hydraulic multiple unit passenger trains developed and built by British Rail Engineering Limited at York Carriage Works between 1984 and 1987. It was designed for regional services across Great Britain and is a second-generation design, built to more modern standards and based on British Rail's Mark 3 body for longer-distance services. It was developed alongside the cheaper Pacers, which were built with bus parts for short-distance routes. Two prototype units were built first, followed by 135 production units in two batches. The units usually run as two-car sets and have a maximum speed of 75 miles per hour, and they were built to replace some of the first-generation diesel multiple units. Later members of the Sprinter group that followed the Class 150 include the Class 155, Class 156, Class 158 and Class 159.
