HO GEN 4-8-8-4 Big Boy Locomotive with DCC and Sound (ATHG-2203)

HO-scale Genesis 4-8-8-4 Big Boy with DCC and Sound is a high-detail Union Pacific steam locomotive model designed to bring the power and presence of the iconic Big Boy to an HO layout. This model includes a built-in DCC decoder with SoundTraxx Tsunami2 sound, dual speakers for rich, room-filling audio, and realistic lighting such as illuminated number boards and headlights, plus a tender back-up light. The headlight can be switched off in reverse, and pivoting front and rear engine units help it tackle curves as tight as 22 inches, with current pickup on all wheels for smooth running on standard HO track.

Designed for serious HO hobbyists, this locomotive offers multiple liveries through the Legendary Liveries program, along with grime-ready finishes and road-number variations to reflect different prototype appearances. It operates on both DC and DCC, with NMRA-compatible CV control and a CV chart included for tuning. Upgraded loco-to-tender connections and dual speakers enhance durability and sound, making it a compelling, ready-to-run centerpiece for a proto-freight or Union Pacific roster on the layout.
