Model: The locomotive is highly detailed prototypical new tooling constructed of metal. For weight reasons, the locomotive has mixed construction (zinc, aluminum, brass). Essential components such as the frame, boiler, locomotive body, cab, and parts of the tender are constructed of die-cast zinc or die-cast aluminum. Other separately applied parts are mostly constructed of metal (brass). This is an extensive model with many separately applied elements and a highly detailed cab. The smoke box door can be opened. The cab doors and much more can be opened. The locomotive has an mfx digital decoder with 32 functions, controlled high efficiency propulsion, and a sound generator with operating sounds synchronized with the wheels as well as extensive sound functions. It can be operated with AC power, DC power, Märklin Digital, and DCC. The locomotive has a built-in buffer capacitor. All driving axles powered. The locomotive has a built-in smoke unit with smoke exhaust and multi-step cylinder steam synchronized with the wheels, a steam whistle, a smoke exhaust pipe, and a safety valve. The locomotive has running gear lights and other lights that can be controlled. The headlights have a light color correct for the era and that change over with the direction of travel. The headlights will work in conventional operation and can be controlled digitally. Maintenance-free, warm white LEDs are used for the lighting. There is an approaching train lamp as well as marker lights and road number lighting.

The locomotive has a red marker light that can be controlled as well as cab lighting and platform lighting. The firebox has digitally controlled, multi-step firebox lighting (flickering) with a soot light. The valve gear switchover is in 3 steps (forward, reverse, continuous operation). There are built-in figures of a locomotive crew.

An accessory package with a coupler set, smoke fluid, and gloves is included with the locomotive. The locomotive is mounted on an aluminum base painted black for display purposes. Minimum radius for operation 1,020 mm / 40-3/16", recommended minimum radius 1,394 mm / 54-7/8". Length approximately 126.5 cm / 49-13/16". Weight approximately 15.6 kilograms / 34 pounds 6 ounces.
