The Deutz OMZ 122 is a diesel locomotive that was built in 176 copies by Humboldt-Deutz in Cologne between 1932 and 1942 . It was intended for use in shunting services; their wheel arrangement is B.

The locomotives were primarily procured by industrial companies for their works railways. For this, the construction was made as simple as possible and the locomotives were built to be as low-maintenance as possible. Since very low speeds were driven, the locomotives are only equipped with a simple gearbox and without a compressed air brake. One wheel set is driven directly, the second driven by coupling rods.

The Deutz OMZ122R series with 176 manufactured copies was the one with the largest sales of the Deutz OM series .

The designation of the locomotive is derived from the engine designation: OMZ 122R means : engine series O = two-stroke diesel engine series O , M = water-cooled, Z = two-cylinder engine, 1 = development stage 1 of the engine, 22 = piston stroke of the engine in cm, R = regular gauge Shunter. The locomotives were available for operation on gauges between 900 and 1,676 mm.

The OMZ 122 belongs to the so-called OM series from Deutz, which comprised numerous versions with different engines for different gauges. So there was a version as OMZ 122 F ( F for light rail) for the track width of 600 mm with a 36 HP crude oil engine and a total weight of 7.8 t. It is 3800 mm long, 1600 mm wide and 2600 mm high. Its wheelbase is 1150 mm. Its top speed is 17.5 km / h. The engine is started with compressed air. In addition, 2 locomotives are known that were manufactured in the meter gauge. These two vehicles are preserved today (2020).

technology

The locomotives have a front end for the machine system and a driver's cab, similar to the DR small locomotive performance group I (Kö). The semicircular shape of the front and the three round cab windows at the front and rear are features of Deutz locomotives.

The machine system is a two-cylinder, two-stroke diesel engine with upright cylinders, which drives a four-speed gearbox with reversing gear via a multi-plate clutch . The drive axle is driven from the gearbox output via a chain, the other axle is driven via a coupling rod . This form of construction saved space, and the running smoothness is increased compared to vehicles with a jackshaft.

Via an angle lever in the middle of the locomotive, both brake pads of the locomotive were braked on the inside.

commitment

The use of the locomotives was easy shunting. They could travel at a very low continuous speed of half walking speed.

There are 30 locomotives either as memorials or in museums:

Osthannoversche Eisenbahnen DL 0605

As an example of a curriculum vitae, the serial number 42990 of the Osthannoversche Eisenbahnen should be reproduced here.

The locomotive was delivered to the Rheinisch-Westfälische Wasserwerkgesellschaft in 1942 . In 1960 it was passed on to the Osthannoversche Eisenbahnen , where it was the smallest locomotive in the stock. Immediately after its takeover, the original engine was swapped for a new three-cylinder engine of the type A3L514 . Thanks to the air-cooled design, the cooling water system could be dispensed with. The service weight of the locomotive was then reduced to 10 t.

The locomotive was used to move the station in Amelinghausen station until 1988 and was then placed in Bleckede . After 1995 the locomotive came to the former Salzwedel Railway Museum, where it was used in shunting. After the museum was closed in 2012, it was transferred to the Historic Locomotive Shed in Wittenberge .

Preserved narrow gauge locomotives

The Frankfurter Feldbahn-Museum (FFM) owns a locomotive OMZ 122 F (V 22) with 600 mm gauge, which was probably delivered in 1936 with the road number 16373. Originally in use near Nuremberg, it ran from 1955 (or 1957) to 1981 at a gravel works near Gudow . Then she came to the Britzer Museumbahn and in 2009 to the FFM. Another locomotive from this gravel railway came via the same route to the Feld- und Kleinbahn Betriebsgesellschaft in Bad Malente and is now with the Feldbahnbetrieb on the Böhmetalbahn .
