HO GEN 4-8-8-4 Big Boy Locomotive with DCC and Sound UP #4020 (ATHG-2206)

The HO-scale Athearn Genesis 4-8-8-4 Big Boy locomotive with DCC and sound is a faithful replica of Union Pacific’s iconic 4-8-8-4 design, scaled for HO layouts. This ready-to-run model features a DCC decoder with SoundTraxx Tsunami2 sound and dual speakers, delivering authentic engine, whistle, and bell effects in both DC and DCC operation.

Designed for dependable performance on typical hobby layouts, it offers illuminated headlights and number boards, a reverse-light in the tender, and a detailed boiler backhead with printed gauges. The drive uses current pickup on all wheels and pivoting front and rear engines to negotiate 22-inch radius curves, while a strengthened loco-to-tender harness improves durability. It presents multiple finish options and Legendary Liveries, including grime-ready variants to capture in-service wear, plus exclusive schemes such as a Greyhound livery. With bright LED lighting and NMRA-compatible CVs for precise slow-speed control, this Big Boy makes a commanding centerpiece on any HO railroad.
