British Rail Class 43 (Warship Class)

The British Rail Class 43 Warship, first classified D800 Warship, was a class of 33 diesel-hydraulic B-B locomotives built by the North British Locomotive Company from 1960 to 1962 and numbered D833 to D865. They were a subclass of the Swindon-built Class 42, but used two MAN L12V18/21B diesel engines, each rated at 1,100 horsepower, with Voith LT306r transmissions, all made by the builder under licence. In service they proved less reliable than the Swindon locomotives because mild steel exhaust manifolds cracked and filled the cabs with fumes. They worked from Bristol Bath Road, Laira, Newton Abbot and Old Oak Common, were withdrawn before their Class 42 sisters and none survive in preservation.
