The Köf III Starting in the mid-Fifties it was evident that the small locomotives Performance Group II were no longer able to meet expectations. For that reason development was begun starting in 1958 for more powerful small locomotives in Performance Group III with more than 150 horsepower because there was a need on the German Federal Railroad (DB) for more powerful small locomotives that could also be used to pull heavy freight trains in transfer service. Power was transmitted from the motor via universal joint shafts to a hydraulic transmission and further by means of roller chains to the wheel sets. Between 1962 and 1966 a total of 312 units as road numbers Köf 11 006-317 were delivered with 240 horsepower motors and Voith transmissions. These units consisted of a frame with an engineer's cab arranged facing the rear. The frame consisted of box-shaped sheet metal members welded together with connecting sheet metal cross member pieces welded into the structure which ensured the necessary rigidity for the design. The interchangeable buffer beams were mounted on prefabricated plank-shaped metal members. The engineer's cab was supposed to give a good view in all directions and was therefore set as low as possible.
