description British Rail Class 57 Overview
The British Rail Class 57 is a fleet of diesel-electric locomotives rebuilt during the late 1990s and early 2000s using redundant Class 47 body shells. The rebuilds were primarily conducted by Brush Traction and involved re-engining the older locomotives with General Motors 12-cylinder 645E prime movers to significantly extend their operational lifespan. These locomotives are utilized by British freight operators and passenger companies for heavy haulage and as rescue locomotives for failed trains.
