HO EMD SD90MAC-H Phase 2 Locomotive UP Wings #8543 (ATHG-1033)

HO-scale EMD SD90MAC-H Phase 2 locomotive in Union Pacific Wings livery. This ready-to-run model is designed for model railroaders seeking a high-horsepower UP powerhouse on an HO layout, delivering prototypical styling and a commanding presence as a centerpiece or working locomotive in a UP roster.

Built for realistic operation, it features a heavy die-cast frame for traction and a detailed surface with LED lighting, see-through steps and cab windows, a full cab interior, etched handrails, and other scale-accurate details. The drive system uses a Genesis-style, five-pole motor with all-wheel drive for smooth, quiet pulling power. It’s DCC-ready with Quick Plug and a 21-pin NEM connector for easy decoder upgrades, and sound-equipped versions add onboard DCC with Tsunami2 sound and dual speakers to reproduce engine, horn, and bell effects. For layout planning, a minimum 18-inch radius is required, with 22 inches recommended for best performance.
