The TR RV class, later known as the EAR 21 class, was a class of 1,000 mm (3 ft 3+3⁄8 in) gauge steam locomotives designed and built for the Tanganyika Railway (TR) as a 4-8-2 development of the 2-8-2 TR MK class. The eight members of the RV class were built by Vulcan Foundry, in Newton-le-Willows, Lancashire (now part of Merseyside), England.

The "RV" class designation was short for "River", as each RV class locomotive was named after a river in the Tanganyika Territory. The class entered service on the TR between 1928 and 1930, and its members were later operated by the TR's successor, the East African Railways (EAR).[2]
