HO GEN 4-8-8-4 Big Boy Locomotive UP 4019 Plastic Model (ATHG-2197)

HO-scale Genesis 4-8-8-4 Big Boy locomotive UP 4019—a highly detailed Union Pacific steam replica designed to anchor a model railroad layout. This iconic 4-8-8-4 model captures the Big Boy’s massive profile and is built to deliver authentic operation on HO-scale layouts, making it a standout centerpiece for layout realism.

Features include illuminated number boards and headlights (headlight off in reverse), a tender back-up light, accurate boiler backhead detailing with printed gauges, and pivoting front and rear engines to negotiate 22" curves. The model uses an on-board DCC decoder with SoundTraxx Tsunami2 and dual speakers for rich, realistic sound on both DC and DCC layouts, with full NMRA compatibility and configurable options. Road-number variants include #4000, #4003, #4019, #4020 and #4024, including Legendary Liveries such as the Greyhound scheme, and Primed for Grime finishes to evoke an in-service look. A front coupler pocket accommodates an operating coupler, and a robust loco-to-tender harness plus current pickup on all wheels contribute to smooth, durable performance on a wide range of layouts.
