The six members of the DL/23 class were built by Beyer, Peacock & Co. in Gorton, Manchester, England, for the Tanganyika Railway (TR). They entered service on the TR in 1923, and were later operated by the TR's successor, the East African Railways (EAR).{{sfn|Ramaer|1974|pp=55–56, 84}} Class listThe builder's and fleet numbers of each member of the class were as follows:{{sfn|Ramaer|1974|p=62}}
