The eighteen members of the class were ordered by the Kenya-Uganda Railway (KUR) immediately after World War II, and were a slightly modified, oil-burning version of the KUR's existing coal-fired EC3 class. By the time the new locomotives were built and entered service, the KUR had been succeeded by the East African Railways (EAR), which designated the coal-fired EC3s as its 57 class, and the new, oil-burning EC3s as its 58 class.{{sfn|Ramaer|1974|p=66}} Class listThe numbers and build dates of each member of the class were as follows:{{sfn|Durrant|1981|pp=189-90}}
