The diesel-mechanical light locomotive of the type V 10 B was manufactured by the LKM Babelsberg for industrial railways and for export. The designation stood for an output of 100 hp and two axles. It was technically based on the N4, which in turn was very similar to the Kleinlokomotiven of power class 2. However, what was new about the V 10 B and the narrow-gauge version V 10 C was that they no longer had a very low driver's cab. The exported locomotives went to several countries in the Eastern Bloc, as well as to friendly countries. The V 15, also built for the Reichsbahn from 1958, was based on the V 10 B, but was more powerful and had hydraulic power transmission.
