HO GEN 4-8-8-4 Big Boy Locomotive with DCC and Sound (ATHG-2210)

HO-scale Athearn Genesis 4-8-8-4 Big Boy with DCC and Sound is a detailed HO-model of Union Pacific’s iconic 4-8-8-4 Big Boy steam locomotive, designed to bring the locomotive’s size and presence to modern layouts. It features an on-board DCC decoder and SoundTraxx Tsunami2 sound for authentic chuff, whistle and bell effects, delivering realistic operation and audio that enhance every run.

Illuminated number boards and headlights, a tender back-up light and finely modeled details such as piping and valves add convincing realism, while current pickup on all wheels and a robust loco-to-tender connection support durable performance on 22-inch-radius curves. The model runs on both DC and DCC, with NMRA-compliant functions and precise slow-speed control, and dual speakers deliver full, immersive sound. Road-number options and Legendary Liveries—including schemes like NdeM #4000—offer flexible choices for building a prototypical roster or proto-freelance scenes on an HO railroad.
