The KHD A4M 220 R / 420 R was a two-axle diesel locomotive with a rod drive that was designed for shunting service. A total of 47 locomotives were built by Klöckner-Humboldt-Deutz (KHD) between 1934 and 1943 , and they were in service until the 1970s.

Four locomotives have been preserved at various locations.


Starting in 1933, the locomotives were built using the modular principle with engines with upright cylinders. The type of engine is included in the locomotive designation. With the KHD A4M 420 R, the result is A = stationary vehicle engine, 4 = number of cylinders, M = type of cooling water-cooled , the following 2 is the second version of the engine with 20 piston strokes = 20 cm. R is a shunter. [1]

The first locomotive was built in 1934 with a type 4 engine. Therefore, it was as KHD A4M 420 R , respectively. Later locomotives are equipped with the motor of type 2 in parallel, the term KHD A4M 220 R were given. [1] [2]

Because of their power and top speed, the locomotives were only suitable for subordinate services. They were used in German plants as well as on private railways such as the Cologne-Frechen-Benzelrath Railway , the Cologne-Bonn Railways , the Brandenburg City Railway and the Bergedorf-Geesthacht Railway . [2]


The locomotives had a machine front and a driver's cab behind it. The power was transmitted by means of a rod drive , with the jackshaft as a transmission output shaft located under the driver's cab between the drive wheels. The locomotives had a connecting rod and a coupling rod as well as a high-speed four-cylinder four-stroke diesel engine from KHD, which was followed by a 4-speed change gearbox with reversing gear after a dry single-disk clutch .

The Brandenburg City Railway's locomotive was switched to run on town gas during the Second World War . The gas bottles required for this were on the roof of the driver's cab. [3]


Portland Zementwerke

At Portland cement works in Erwitte , a locomotive was put into service in 1937 to move the works. It was retired in 1981. In 2002 it was erected as a memorial in front of the plant in Erwitte. [5]

Dynamit AG

At Dynamit AG in Herzberg , a locomotive was discontinued in 1941 and named D2 . It was sold to a private company in Cologne in 1946 . In 1991 the locomotive was handed over to the Rheinische Industriebahn-Museum in Cologne. [6] [7]

Coswig paper mill

The Coswig paper factory received a locomotive in 1941, which in 1967 was passed on to the Erzgebirge cardboard and cardboard factory in Raschau . It was located there until 1993 and was then given to the Schwarzenberg Railway Museum. [8] [9]

VW works

In 1943, the VW works in Fallersleben received a locomotive to move the works. It remained in various company divisions until 1965 and was then passed on to Rheinstahl Nordseewerke in Emden . She stayed there until the early 1990s and has been with the Ostfriesland Coastal Railway Museum Railway since 2001 . [10] [11]

Brandenburg city railway

The diesel locomotive was used by the Arado aircraft factory before it was used on the private railway . From 1946 it was listed as number V 95 on the Brandenburg city railway . The whereabouts of the locomotive are not known.

Meppen-Haselünner Railway

The locomotive with the serial number 26130 was procured in 1939 by the procurement office for airport construction, Berlin, for Achmer airport near Bramsche and after the war it was part of the Deutsche Bundesbahn as Kö 6040 , but was taken out of service again in 1951.

The locomotive then served as a shunting device in the inventory of the Hamburg-Harburg repair shop ( works locomotive 2). The locomotive came to the Meppen-Haselünner Railway at a point in time that was not known in terms of time and was put into operation there in 1967 after major repairs. The locomotive only had a handbrake and could therefore only move two cars. In 1972 the locomotive was shut down. In 1986 she came to the Paderborn Museum Railway in Paderborn . Here it was visually refurbished, but sold to a scrap dealer in 1988 and scrapped in 1991. [12] [13]
