British Rail Class 42

The British Rail Class 42, the Swindon-built Warship, was a class of diesel-hydraulic locomotives introduced in 1958 for the Western Region of British Railways. Its design scaled down the German Federal Railway's V200 to fit the smaller British loading gauge, under a licence with the German manufacturers. The locomotives built at Swindon Works were numbered D800 to D832 and D866 to D870, while a further 33 built by the North British Locomotive Company became Class 43. Most were powered by two Maybach MD650 engines built under licence by Bristol Siddeley and coupled to Mekydro transmissions, and nearly all carried the name of a Royal Navy ship. Withdrawals began in 1968 and the last were withdrawn by the end of 1972.
