The British Rail Class 158 Express Sprinter is a Diesel Multiple Unit (DMU), built specifically for British Rail's Provincial Services sector between 1989 and 1992 by British Rail Engineering Limited (BREL) at Derby Litchurch Lane Works and outshopped in Regional Railways Provincial livery.
They were built to replace many locomotive-hauled passenger trains, thereby reducing cost of operation, and to allow cascading of existing Sprinter units to replace elderly'heritage' DMUs. The majority of the 182-strong fleet of Class 158 units were built as two-car sets, with 17 three-car units constructed specifically for use on Trans-Pennine services. Similar three-car units were built for use by Network SouthEast but these were converted to Class 159 specification before introduced into service, with toilet retention tanks and other modifications to operate over the third-rail network. All but one of the Class 158s remain in service today (2023), with operators including ScotRail, Northern, Great Western (GWR), East Midlands Trains (now EMR), and Transport for Wales (formerly Arriva). Former operators include Central Trains.
The Class has worked extensively across the UK network, even into East Anglia as far as Stansted Airport and Norwich. Some 158s have been converted to additional Class 159s and now operate for South Western alongside their original classmates.
