British Rail Class 29
From Wikipedia, the free encyclopedia
The British Rail Class 29 consisted of 20 diesel locomotives which were rebuilt from the North British Class 21 in 1964-1965 at Polmadie Works with a Paxman 'Ventura' V12 engine (predecessor to the HST 12RP200 'Valenta' engine). Although these offered more power and much improved reliability over the MAN engined Class 21s they were not retained due to their small class size, and the use of a high speed diesel engine. The class 29s were withdrawn at the end of 1971 and no locomotives survive today. along with the class 21s
