The KUR EC2 class, later known as the EAR 52 class, was a class of gauge Garratt-type articulated steam locomotives operated by the Kenya-Uganda Railway (KUR) and the East African Railways (EAR).
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.
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.
The numbers, build dates and names of each member of the class were as follows:
