N GEN 4-8-8-4 Big Boy Locomotive with DCC and Sound, UP #4019 (ATHG-2255)

An N-scale Genesis 4-8-8-4 Big Boy locomotive with DCC and sound for Union Pacific UP 4019. This high-fidelity model brings the iconic 4-8-8-4 Big Boy to life in a compact N-scale package, built for both display and operation on a model railroad. Equipped with an onboard DCC decoder and SoundTraxx Tsunami2 sound, it delivers authentic chuff, whistle, and bell effects and runs on both DC and DCC layouts.

Built around a heavy die-cast frame for traction and featuring prototype-inspired detailing, see-through running boards and cab windows, body-mounted scale knuckle couplers, and directional LEDs that maintain a constant brightness, this model is ready to run right out of the box. It’s designed with accuracy in mind, supports full DCC functionality and multi-unit operation, and fits typical N-scale layouts with a minimum 11-inch radius for smooth, realistic operation.
