British Rail Class 48

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. 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.
