The English Electric Company used three locations to build locomotives fitted with the 12CSVT Diesel engine, two in the United Kingdom and one in Australia. The Vulcan Foundry at Newton le Willows on Merseyside and the Darlington Works of Robert Stephenson & Hawthorn produced locomotives from 1959 to 1970, whilst Rocklea Works at Brisbane in Queensland produced locomotives from 1966 to 1976. A full history of the company appears in the ´Growlette´ section of the site.
The class lists have been divided into two separate lists, ´British Built´ and ´Australian Built´, each accessible from the links to the left. The menu is then divided again into three possible sections, New contains classifications of locomotives when they were new to service, Rebuilt includes classes that were either rebuilt or reclassified during their working life but retained the English Electric 12CSVT diesel engine, the last topic is Re-Engined which as suggests, means that a new class was created when a locomotive was rebuilt or reclassified but was fitted with an alternative engine instead of the E.E.12CSVT or indeed no engine at all. All will be explained as you delve deeper into the site and class information.
