Biography

British Rail Engineering Limited (BREL) was a wholly-owned subsidiary of British Rail established on 1 January 1970 (under the Transport Act 1968) to consolidate the British Railways Workshops into a single corporate engineering entity. Its 13 main sites at formation, including Crewe, Derby, Doncaster, Eastleigh, York, Swindon and Wolverton, between them undertook all major BR new-build and heavy overhaul work.

BREL's design portfolio in the 1970s and 1980s spanned the Class 56 (1976), Class 58 (1983), the High Speed Train (HST/Class 43) power car (1976), the Class 150–158 Sprinter family of diesel multiple-units, and the Class 313–323 series of electric multiple-units. From 1989 BREL was progressively privatised; the locomotive-building component became BREL Limited and was sold to ABB Transportation in 1992 (later ADtranz, then Bombardier, and now Alstom Transport UK).
