Source-derived summary

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).

Specifications

The design of the GA class locomotives was based upon that of the KUR EC2 class, which was built at about the same time by the North British Locomotive Company for the Kenya-Uganda Railway (KUR). The main design difference was that the GAs had higher, narrower front tanks than the EC2s. With their reduced water capacity, the GAs also had a lower axle loading, which made them suitable for operation over the World War I-damaged bridges on the Central Line.

Service history

Upon entry into service in 1931, the GA class locomotives were allocated numbers 300–302. Each of them was also given a name: the first two carried the names Arusha and Iringa, respectively, after the locations of the TR's big road depots, and no. 302 was named Bukoba, as that town had a jetty for marine services.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1930, 1931—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with class, East and African providing the first useful test.
