Limited Edition Union Pacific Challenger

The model is constructed of heavy-duty metal and features many attached details. Distinctive air deflectors, attached metal handrails, and driver and fireman figures in the cab underscore the high-quality and prototypical appearance.

For operation, the locomotive is equipped with an mfx+ digital decoder. Extensive lighting, operating, and sound functions, together with the powerful speaker in the tender, ensure a particularly realistic experience.

The speed-dependent dynamic smoke emission is standard and digitally controllable. Additionally, the locomotive features a buffer storage system to bridge short sections without power.

The regulated high-performance drive with a flywheel in the boiler powers 6 axles. The curve-friendly articulated running gear, Boxpok wheels, and traction tires support the powerful operation of this heavy U.S. steam locomotive in H0 scale.
