The TR MK class, later known as the EAR 25 class, was a class of 1,000 mm (3 ft 3 3⁄8 in) gauge 2-8-2 steam locomotives. The eleven members of the class were built by Vulcan Foundry, in Newton-le-Willows, Lancashire (now part of Merseyside), England, for the Tanganyika Railway (TR). They entered service on the TR in 1925–1926, and were later operated by the TR's successor, the East African Railways (EAR).[2]
