Trix 25913 H0 U.S. Class 3900 "Challenger" Steam Locomotive, UP, Era VI

Are you looking for an exceptional U.S. steam locomotive for your H0 layout that combines impressive size, state-of-the-art digital technology, and high collector's value? The Trix 25913 US Class 3900 “Challenger” Steam Locomotive of the Union Pacific Railroad is an impressive model of one of the most famous American steam locomotives.

The prototype is a heavy U.S. Class 3900 “Challenger” steam locomotive in the modified version with an oil tender. This version depicts museum locomotive 3977 as it appeared at Cody Park in North Platte, Nebraska. Thus, the model combines historic railway technology with a unique museum-style design.

Limited Edition Challenger from the Union Pacific Railroad

The locomotive impresses with its heavy-duty metal construction and numerous attached details. Distinctive air deflectors, Boxpok wheels, swiveling steam pipes on the front bogie, and the engineer and fireman figures in the cab ensure a particularly realistic representation.

The regulated high-performance drive with a flywheel in the boiler powers six axles and, together with the curve-friendly articulated running gear and traction tires, ensures powerful running characteristics.

DCC/mfx digital technology with dynamic smoke emission

The RailCom-compatible DCC/mfx digital decoder offers extensive lighting and sound functions. In addition to typical operating sounds such as oil and water intake, sounds from the opening and closing of sliding windows and ventilation flaps in the cab can also be digitally controlled.

The standard-equipped smoke generator produces speed-dependent dynamic smoke emission, which is also digitally controllable. A buffer memory bridges short power-free sections and ensures safe operation.
