The TR GA class, later known as the EAR 53 class, was a class of 1,000 mm (3 ft 3+3⁄8 in) gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives. The three members of the class were built in 1930 by Beyer, Peacock & Co. in Manchester, England, for the Tanganyika Railway (TR). They entered service in 1931, and, with one exception, were later operated by the TR's successor, the East African Railways (EAR).
