The locomotives with road numbers 51 to 53 of the Brandenburg city railway were tank locomotives with a 1'D1 'wheel arrangement with two-cylinder superheated steam engines. They were delivered by Borsig in 1937 (numbers 51 and 52) and 1939 (number 53) and were the last new locomotives from the commissioning railway administration. They were not given names. 1940 to 1949 they had the train numbers 1-200 to 1-202 and were redesignated as 93 6476, 93 6477 and 93 6479 after they were taken over by the Deutsche Reichsbahn . At least the 93 6479 was still in operation in 1962, the 93 6476 was still in 1966 in the inventory of the Deutsche Reichsbahn.
Locomotives of a similar design, but with smaller coupling wheels only 1130 mm in diameter and with surface preheaters, were also procured from the same manufacturer by the Niederbarnimer Eisenbahn from 1940 to 1942 as track numbers 010 to 014. These were redesignated by the Deutsche Reichsbahn as 93 6679 to 93 6683.
