EAR 30 class

The EAR 30 class was a class of oil-burning 1,000 mm (3 ft 3 ³⁄₈ in) gauge 2-8-4 steam locomotives. The class was built in 1955 by North British Locomotive Company in Glasgow, Scotland, for the East African Railways (EAR). Its design was derived from the 2-8-2 EAR 29 class, which, in turn, was based upon the Nigerian Railways River class.[2]
