The six members of the ML class were built in 1947 by W. G. Bagnall , in Stafford , England, and delivered to the TR. They were later operated by the TR's successor, the East African Railways (EAR), as its 26 class. In 1952, six further members of the 26 class were delivered to the EAR. They had been built by Vulcan Foundry , of Newton-le-Willows , Lancashire (now part of Merseyside ), England, and Robert Stephenson and Hawthorns of North East England .
