Marklin 36811 - Diesel Locomotive KoeF 381

Model: The locomotive comes with a digital decoder and a controlled miniature can motor. 2 axles powered. 2 track adhesion magnets for greater pulling power. Separately applied metal grab irons. The locomotive has dual headlights the will work in conventional operation and can be controlled digitally. The upper headlight does not work. The acceleration / braking delay can be controlled with a Control Unit or Märklin Systems. Length over the buffers 7.4 cm / 2-15/16".

Prototype:Switch Engine Dwarf with Storage Battery Power - From 1935 to 1937 a total of 41 locomotives with electric traction motors suspended over the axles powered by storage batteries were built parallel to the small locomotives built with diesel and Otto motors. Similar frames were used as a basis as with the variations with combustion motors. For that reason the locomotives designated as the class Ks were very similar externally to the class Kö (small locomotive with an diesel oil motor) and the class Kb (small locomotive with a gasoline motor) and had a comparable power output. The critical advantages of this class were that it was immediately ready to be run and could be used in areas or plants where exhaust gases were prohibited due to the danger of explosion. The DB still had a number of these locomotives powered from storage batteries well into the 1980"s. They were initially designated as the class Ka and later with the computer numbering designation 381. Several units were then acquired by private firms and museums.
