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]
