This locomotive is designed for operation on 0 gauge track (32mm gauge). Recommended diameter of curved rails is 137cm. When driving curves with a diameter of 125 cm, it is necessary to insert a straight track in front of the switch so that the locomotive does not drive out of the curve directly into the deviation of the switch. It can be operated with 0-18 volts of direct current or with pulse voltage from an ETS controller. A consumption of the locomotive is 1-2 amps. The locomotives´s two motors and great weight combine to ensure substantial pulling power. All driving axles are equipped with the ETS clutch mechanism, which allows the wheels to be turned when the power is shut off. Each locomotive is carefully manufactured and individually tested. All locomotives have serial numbers on their frames. All metal construction.
