The EAR 58 class was a class of 1,000 mm (3 ft 3+ 3 ⁄8 in ) gauge 4-8-4+4-8-4 Garratt -type articulated steam locomotives built by Beyer, Peacock & Co. in Manchester , England, in 1949.
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.
The numbers and build dates of each member of the class were as follows:
