Production

The ten members of the class were ordered by the 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.[2]

Service history

The whole class entered service in 1931, and its members were later operated by the KUR's successor, the EAR, both in Kenya/Uganda and in Tanzania.[2]
