Prototype: German Federal Railroad (DB) class 81 heavy switch engine.
Model: The locomotive comes with a digital decoder. 4 axles powered. 2 traction tires. Relex couplers in NEM coupler pockets. The triple headlights change over with the direction of travel, will work in conventional operation, and can be controlled digitally. The acceleration and braking delay can be controlled digitally with a Control Unit or Märklin Systems. Length over the buffers 12.8 cm / 5-1/16".
Almost all of the current Era III cars from Central European railroad prototypes go well with this train set.
