HO GEN 4-8-8-4 Big Boy Locomotive Legendary Liveries SOU #4075 (ATHG-2201)

HO-scale Genesis 4-8-8-4 Big Boy locomotive in Legendary Liveries, Southern Railway SOU 4075, is a meticulously detailed, sound-equipped model for HO layouts. It features illuminated number boards and headlights, a tender back-up light, and synchronized chuff, whistle, bell, blow-down, air compressor, dyno and pop-off valve sounds from a DCC-compatible SoundTrax Tsunami2 decoder with dual speakers for rich, realistic sound in both DC and DCC operation. Realistic detailing includes a boiler backhead with printed gauges, piped fittings, and individually applied parts, plus a rugged loco-to-tender connection and current pickup on all wheels to keep long trains moving smoothly. The model can negotiate tight 22-inch-radius curves, making it a striking centerpiece on a capable HO layout.

As part of the Legendary Liveries program, this Big Boy wears a distinctive Southern Railway SOU 4075 paint scheme and road-number-specific finish variations, including as-delivered and Primed For Grime looks as well as other scheme options such as the Greyhound-era yellow-trim version. It supports full DCC operation with NMRA-compliant CVs for precise slow-speed control and MU lashups, and includes a CV chart for reference. Weathering-ready by design, it invites hobbyists to add grime and rust for a lifelike presence on an authentic-looking HO layout with a dramatic, era-appropriate centerpiece.
