British Rail Class 150/2

The BR Class 150/2 is the production subclass of the Class 150 Sprinter family, distinguished from the earlier Class 150/1 prototype batch by its longer 23-metre body — approximately 3 metres longer than the 150/1's 20-metre cars — giving greater passenger capacity per vehicle. The 150/2 was built at BREL York between 1986 and 1987 and forms the bulk of the Class 150 fleet.

In all other respects the 150/2 shares the mechanical specification of the wider Class 150 family: Cummins NT855R engines, hydraulic transmission, bogied underframe, and 75 mph maximum speed. The longer body is the primary visible distinction, giving the 150/2 a slightly more substantial appearance than the 150/1 and a meaningfully greater seating capacity that made the subclass more suitable for busier regional routes.
