The Western Regions first production diesel-hydraulics introduced in 1958 and based on the German V200 locomotive design. The Warship locomotives were split into two classes, Class 42 for Bristol Siddeley Maybach engined examples and Class 43 with NBL/MAN power plants. As with the Class 52's their hydraulic transmission deemed them non-standard and withdrawals began in 1968 with the final machine leaving its BR employ in December 1972.
