The DR HK 94-100 is a Mallet locomotive that was built in 1918. 7 copies were built by her for use on army-run railways. Some of them are still in use with the "Harzer Schmalspurbahnen".
 The model can be motorized with a Power Functions XL motor. The engine is installed in the driver's cab, the battery box and the IR receiver in the boiler. Due to the engine and the gearbox, this locomotive has a similar pulling power as the "Smaragd Express" from LEGO. The model is equipped with numerous details, such as the functioning chassis, the boiler superstructures or the detailed driver's cab (only for the driver's cab variant). Depending on the version, it consists of approx. 505 individual parts and is approx. 34 knobs long. The locomotive offers excellent driving characteristics.
