           De K staat voor Kleinlokomotive, de ö voor Öl (dieselmotor), de f voor
           Flüssigkeitsgetriebe (hydraulische aandrijving). Daarachter kan met een Romeins cijfer
           (I, II of III) worden aangegeven tot welke Leistungsgruppe het locje behoort. 
           Dit locje is een Köf II (50-150 pk) in dienst bij Dampf Lokomotive Werkstatt Meiningen.
           Het ontwerp dateert uit 1932. In de jaren vijftig is een grote vervolgserie gebouwd.
           Ook zijn veel oudere locs aangepast, zodat er nogal wat verschillende subtypen
           bestaan.
           Er is ook een versie gebouwd die op accu's reed, type Ka (A = Akkumulator).
           In Oost-Duitsland zijn in de jaren vijftig ook Kö II's gebouwd, met een mechanische
           overbrenging.
           German Kleinlokomotiven (literally: small locomotives) like the DRG Kö II 
           (later: Köf II) were developed as locomotives with a low weight and driving power for
           light shunting duties. There were two classes, based on engine power. 
           The Class II were engines which developed more than 40 (later 50) PS.
           After tests with several trial locomotives, they were placed in service from 1932
           onwards by the Deutsche Reichsbahn (DRG) and used on small stations for light shunting
           and marshalling work. They were intended to make the handling of goods traffic more
           economical. To do that an appropriately-trained controller had to be able to handle
           shunting duties using the locomotive. Accordingly the locomotive was designed to be
           robust and easy to operate.
           Light locomotives mainly used diesel motors (originally classified as Kö/Köf/Köe by
           the DRG), as their source of energy, but there were also versions with Benzolmotors,
           designated as Kb/Kbf/Kbe, and with electrical batteries (accumulator cars: Ks/Ka), as
           well as one locomotive with a steam engine. The third letter indicated the type of
           power transmission. If there wasn't one, the locomotive had a gear system. An f stood
           for an hydraulic drive and an e for electric traction motors, that were fed by a
           generator. Köf, therefore, stood for a light locomotive (Kleinlok) with diesel
           (Öl-(Diesel-)Motor) engine and hydraulic transmission (Flüssigkeitsgetriebe).
           The locomotive is very small and of standard gauge size, but only fills about half the
           loading gauge profile. As a result, it can be loaded onto flat wagons. That was
           necessary, because if it had to move under its own power, its top speed of only 30
           km/h would have seriously held up rail traffic. It is driven by a diesel engine,
           that works through a mechanical gear transmission system and dry clutch. Power is
           transmitted to the axles using a chain linkage.
           The light diesel locomotives were the first German diesel engines that were built in
           batches by several manufacturers. They were initially divided into two power groups:
           * Class I (initially 40, later 50 PS)
           * Class II (up to 90 PS)
           In the DR and DB over 100 new Köf II engines were further developed and built after
           the war. In the DR over 60 vehicles were produced and referred to as N4 by the 
           manufacturers. These resembled the classical light locomotive very closely, but had a
           side rod drive. The first real development of the Köf in the GDR was the V15/V23. 
           As in the DB, a decision was made to build a Köf III. This plan was subsequently
           discarded and replaced by the DR V60 project.
           The DB later developed a Köf III with up to 240 PS. In 1987, the Class 260/261 
           (up to 1968 called V 60) engines were classified as light locomotives.
           The brake effort of the Kö was initially only the weight of the engine driver and the
           maximum force he could transmit via the brake pedal. With the introduction of new,
           more powerful motors (up to 128 PS) and the corresponding increase in tractive effort
           this proved far too little; as a result many light locos in the DB and DR were
           equipped with a compressed-air brake, that could also operated the brakes of attached
           wagons. In the DB the permitted top speed was raised from 30 to 45 km/h where
           compressed-air brakes had been installed. These locos can be easily recognised by
           their air reservoirs on the front. Because the open cab gave no real protection from
           the weather in winter, these were added during the course of main inspections from
           the late 1950s.
