The British Rail Class 158 Express Sprinter is a diesel multiple-unit (or DMU), built specifically for British Rail between 1989 and 1992 by British Rail Engineering Limited (BREL) at its Derby Litchurch Lane Works. They were built to replace many locomotive-hauled passenger trains, and allowed cascading of existing Sprinter units to replace elderly 'heritage' DMUs. The Class 159 DMUs are almost identical to the Class 158s, having been converted from Class 158 to Class 159 in two batches.
When introduced, British Rail described the Class 158s as bringing "new standards of comfort and quality to rail travel on Regional Railways' key long-distance cross-country routes". As built, interiors were described as fully carpeted, with "panoramic" windows and a variety of seats arranged both airline-style and in bays of four around tables. Unlike previous members of the Sprinter family, such as the Class 156 SuperSprinter, the Class 158s featured air conditioning, an on-board payphone, power-operated interior doors, a toilet in each carriage, and provision for a refreshment trolley service. Despite an increased top speed of 90 miles per hour (140 km/h), the units also promised a smoother, quieter ride than its predecessors. The Class 158s were expected to achieve 13,500 miles of operation between major services and a range of up to 1,600 miles from each refuelling.
