The EAR 27 class, previously known as the EAR MR class, was a sub-class of 1,000 mm (3 ft 3+3⁄8 in) gauge 2-8-2 USATC S118 Class steam locomotives operated by the East African Railways (EAR), and, with one exception, previously by the Malayan Railways.

Service history

The first eight members of the class were built in 1944, and were acquired second hand by the Tanganyika Railway (TR) from the Malayan Railways in 1949. Those locomotives entered service on the Central Line in Tanganyika in 1949. By that time, the TR had been succeeded by the EAR, which designated them for a very short time as its MR class, but then, as part of a comprehensive reclassification of all of its locomotives, redesignated and renumbered them as its 27 class.

In 1950, the EAR acquired eight further 27 class locomotives from the Malayan Railways, and in 1953 another 27 class locomotive was built in the EAR's Dar es Salaam Workshops, using spare parts acquired from the Nigerian Railways. The 27 class therefore eventually reached a total of 17 locomotives.

Class list

The builders, build year and fleet numbers of each member of the class were as follows:
