Background
The machines were produced from 1963 onwards from the North British Type 2 (later Class 21 under TOPS) by replacing the original unreliable licence-built MAN of the Class 21s with Paxman Ventura V12 engine at Paxman's Colchester works. The first unit to be re-engined was D6123, a further 19 machines were re-engined in 1965–1967 at Glasgow Works and mostly Inverurie Works, along with other modifications including the fitting of four-character headcode displays in the nose ends (D6123 retained its original front ends and so did not receive a headcode panel). After rebuilding, they returned to service from Eastfield depot in Glasgow. The allocation of all twenty locomotives in August 1967 was Eastfield. Withdrawal
Although these offered more power and much improved reliability over the original Class 21s, they did not survive much longer, due to their small class size and the use of a non-standard high-speed diesel engine. D6108 was withdrawn in May 1969 and scrapped by McWilliams of Shettleston in 1971, while the other 19 were withdrawn between April and December 1971 and scrapped at BR's Glasgow Works in 1971–72.
