The British Rail Class 48 was a diesel locomotive class which consisted of five examples, built at Brush Falcon Works in Loughborough and delivered between September 1965 and July 1966.[1] They were part of the British Rail Class 47 order, but differed from their classmates by being fitted with a Sulzer V12 12LVA24 power unit producing 2,650 bhp (1,976 kW), as opposed to the standard 12LDA28C twin-bank twelve-cylinder unit of the remaining fleet.
