The ten members of the class were ordered by the Kenya-Uganda Railway (KUR). Unusually, they were built by North British Locomotive Company in Glasgow, Scotland, instead of Beyer, Peacock & Co., the builder of all the KUR's other Garratt locomotives. They entered service in 1931, and were later operated by the KUR's successor, the East African Railways (EAR), both in Kenya/Uganda and in Tanzania.[2]
