The frame and the truck frames are constructed of metal. The superstructure is constructed mostly of metal. The locomotive has an mfx digital decoder, controlled high-efficiency propulsion, and extensive sound functions. It can be operated with AC power, DC power, Märklin Digital, and DCC. The locomotive has a powerful, centrally mounted motor and drives all of the axles in both trucks by means of cardan shafts. The white headlights and red marker lights are LEDs. They will work in conventional operation and can be controlled digitally.
White LED lights are on in the engineer's cab at the front of the locomotive, depending on the direction of travel. The doors for the engineer's cab can be opened. The cabs have interior details and Engineer's Cab 1 has a figure of a locomotive engineer. There are metal grab irons and many other separately applied details: DB sign plates, antenna, windshield wipers, a whistle and buffer beams with sprung buffers and separately applied brake lines.
The locomotive comes from the factory with claw couplers mounted on it; they can be replaced by 2 reproduction prototype couplers that are included with the locomotive. The minimum radius for operation is 1,020 mm / 40-1/8". Length over the buffers 51.5 cm / 20-1/4".
