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 {{Whyte|2-8-2}} EAR 29 class, which, in turn, was based upon the Nigerian Railways River class.{{sfn|Ramaer|1974|pp=80–81}} The 26 members of the class served their entire careers in Tanganyika/Tanzania, one of the three territories/countries served by the EAR.{{sfn|Durrant|Lewis|Jorgensen|1981|p=83}} Class listThe numbers and names of each member of the class were as follows:{{sfn|Ramaer|1974|p=83, 89}}
