Model: The locomotive has an mfx+ digital decoder and extensive sound functions. It also has controlled high-efficiency propulsion with a flywheel, mounted in the boiler. 3 axles powered. Traction tires. The locomotive and tender are constructed mostly of metal. A 7226 smoke unit can be installed in the locomotive. The triple headlights change over with the direction of travel. They and the smoke unit that can be installed will work in conventional operation and can be controlled digitally. The locomotive has firebox flickering that can also be controlled digitally. Maintenance-free warm white and red LEDs are used for the lighting. There is a permanent close coupling with a guide mechanism between the locomotive and tender that can be adjusted for track curves. The rear of the tender has a guide mechanism and a close coupler with an NEM pocket. A mechanism is built into the tender to lower the coal load in order to represent visually the consumption of coal in the tender in the World of Operation mode. For digital central controllers without mfx+ the lowering and raising of the coal load can be activated by means of special function F8. The minimum radius for operation is 360 mm / 14-3/16". Protective piston sleeves, brake hoses, and figures of a locomotive engineer and a fireman are included. Length over the buffers 27.5 cm / 10-13/16".
