HO EMD SD90MAC-H Phase 2 Locomotive UP #8561 (ATHG-1035)

HO scale EMD SD90MAC-H Phase 2 Locomotive in Union Pacific livery, road number 8561, is a highly detailed, ready-to-run model designed for serious HO-scale layouts. Built around a heavy die-cast frame for traction and a Genesis driveline with a 5-pole motor for smooth, quiet operation, it features authentic prototype detailing—from etched see-through steps to a full cab interior and LED lighting—so it captures the presence of the prototype on the layout. Designed for easy integration into modern layouts, it offers DCC-ready plug-and-play with a 21-pin NEM connector, reliable all-wheel electrical pickup, and RP25-profile wheels for dependable operation on common tracks, plus body-mounted knuckle couplers for straightforward coupling.

Sound-equipped versions add onboard DCC decoding with Tsunami2 sound and dual speakers, delivering engine, horn, and bell sounds that function in both DC and DCC modes and offering full NMRA compatibility with CV-based tuning. The prototype accuracy continues with careful paint and lettering, while the heavy frame and precise gearing provide solid pulling power and realistic operation, making it a compelling centerpiece for Union Pacific power on a hobbyist’s HO-scale layout.
