Model: The locomotive frame, boiler, and tender are constructed chiefly of metal; the engineer's cab and separately applied parts are made of plastic. The locomotive has an mfx digital decoder with motor control. It can be run with DC power, AC power, Märklin Digital, and Märklin Systems. The locomotive has a powerful RE-max motor with a bell-shaped armature, made by the firm maxon motor ag. All of the driving axles are powered. The headlights are LEDs, they will work in conventional operation and can be controlled digitally. The engineer's cab lighting and the running gear lights, many other operating sounds, and the acceleration and braking delay can be controlled with Märklin Systems.
