The KUR EC4 class, later known as the EAR 54 class, was a class of 1,000 mm (3 ft 3 ³⁄₈ in) gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives developed under and for use in wartime conditions.

The seven members of the class were built during the latter stages of World War II by Beyer, Peacock & Co. in Manchester, England, for the War Department of the United Kingdom and the Kenya-Uganda Railway (KUR). They entered service on the KUR in 1944, and were later operated by the KUR's successor, the East African Railways (EAR).^[2]
