4-6-6-4 Challenger with Coal Tender - 3-Rail - Sound and Digital -- Union Pacific 3969 (1950s, black, silver)

Based on UP's powerful 4-6-6-4s of the 1950s, this superb replica features all-metal construction and traction tires for superb pulling power, close-coupling between engine and tender, and a flywheel-equipped drive for smooth performance. Loaded with features including DCC and sound, warm-white LEDs power the constant and directional headlights, and the model also features selectable class lights, numberboards and cab lighting that can be turned on or off separately. A powerful speaker is mounted in the tender, and the model includes a full range of sounds from coal and water refilling, to opening and closing cab windows and vents! Like the prototype, the model is equipped with two stacks, and both can be fitted with smoke generators (441-7226), sold separately if desired. There's even a handsome wooden presentation box, perfect for transport or display. Like the prototype, this large model (16-3/4", 42.5cm long) works best on larger curves, but can handle a minimum radius of 14-13/16"
