The DWK D350 was a three-axle diesel locomotive with mechanical power transmission and rod drive , which was designed for the middle shunting service in the performance class similar to the Wehrmacht locomotive WR 360 C 14 of the Deutsche Reichsbahn. It was built in 1938 by Deutsche Werke in Kiel and was the prototype of a subsequent series.

The locomotive was in operation until 1974 and is no longer available today.

development

In 1938, Deutsche Werke delivered the first shunting locomotive for the German Wehrmacht . Compared to the WR 360 C 14, it had mechanical power transmission and was equipped with a central driver's cab and two stems.

It was tested by the Deutsche Reichsbahn in the LVA Grunewald . According to the final report, it had a higher starting tractive effort; the interruptions in tractive effort when shifting the mechanical transmission were less favorable. The smooth running at higher speeds has been viewed negatively, for which the small wheelbase and the out-of-axle group Blindwelle were blamed. The locomotive had different Achsdrücke , characterized occurred in certain situations to roll . For the subsequent DWK 360 C , the entire construction had to be completely changed by the manufacturer.

This one locomotive was delivered to the Reich Ministry of Aviation in Berlin . It came from the manufacturer's range from 1932, the series locomotives were part of the 1938 range.

technology

Compared to the WR 360 C 14, which had been produced since 1937, the DWK construction had its own engines and gearboxes. The visibility over the smaller porch was better. The motor was housed in the larger front end and the transmission in the smaller one. Power was transmitted from the engine to the gearbox by a shaft under the cab floor.

The machine system consisted of a six-cylinder four-stroke diesel engine DWK 6M 30 from DWK, which could originally be started with compressed air. The engine delivered its power via a multi-plate clutch to a mechanical four-speed gearbox, which was also controlled with compressed air. The gearbox had a secondary gearbox for the top speeds of 30 km / h and 60 km / h. The jackshaft located outside the axle group was used to drive an axle via a drive rod and the other axles with coupling rods. The advantage of the shorter connecting rod on the closest axis led to a less than ideal mass balance, which led to a negative assessment.

commitment

DB V 36 310

After the delivery to the Reich Aviation Ministry, the locomotive was in the locomotive count in Bremen after the Second World War in 1947 and was designated as V 36 310 . In 1949 it came to the Deutsche Bundesbahn and was classified there as V 36 310 . The unique piece was used in front of a rail grinding train and especially in the Hanover area, where it had the device number 9678 . It had a special speed controller for particularly constant slow travel. In 1961 the rail grinding train was replaced and the locomotive was dispensable.

WLE VL 0608

In October 1961, the Westphalian State Railroad acquired the locomotive. During the main repair, it got a new engine and was prepared for one-man operation. The first use took place in 1963. It was used in shunting and freight train services from the Warstein and Soest stations .

In 1973 it was shut down after a gearbox damage and a year later it was scrapped in Lippstadt .
