Model: The locomotive is completely new tooling with the frame and locomotive body with boiler constructed of die-cast zinc. Other separately applied parts are mostly made of metal. This is a highly detailed model with many separately applied details and a detailed engineer‘s cab. The locomotive has older design buffers, does not have a raised addition to the coal bunker, a prototypically long smoke stack, a reproduction of the smoke box door with a central locking mechanism, a water tank hatch that can be opened, a sand dome that can be opened, cab doors that can be opened, and much more. The locomotive has an mfx digital decoder, controlled high-efficiency propulsion, and a sound generator with operating sounds synchronized with the wheels as well as extensive sound functions. The locomotive can be operated with AC power, DC power, Märklin Digital, and DCC. 3 axles powered. The locomotive has a built-in smoke unit with smoke exhaust synchronized with the wheels, cylinder steam, and a steam whistle. The locomotive has dual headlights that change over with the direction of travel with a reproduction of the gas lamps for oil gas and a light color correct for the era. The headlights will work in conventional operation and can be controlled digitally. Maintenance-free warm white LEDs are used for the lighting. Cab and firebox lighting are included. The locomotive has a prototype reproduction coupler on the front and a claw coupler on the rear. Both can be changed to the other type of coupler. An accessory package with a prototype reproduction coupler and a claw coupler, smoke fluid, and figures of an engineer and fireman is included with the locomotive Minimum radius for operation is 1,020 mm / 40-1/8“. Length over the buffers 39.7 cm / 15-5/8“.
