HO GEN SD90MAC Locomotive w/DCC & Sound, UP #3712 (ATHG-1932)

An HO-scale Union Pacific SD90MAC diesel locomotive with DCC and sound, UP 3712, this Genesis model delivers authentic power and detail for serious model railroaders. Fully assembled and ready to run, it features a heavy die-cast frame for traction, LED lighting with lit number boards and truck lights, etched see-through steps, a full cab interior, and fine-scale Celcon handrails for a lifelike silhouette. The onboard DCC decoder with SoundTraxx Tsunami2 sound provides engine, horn, and bell effects that operate in both DC and DCC modes, with full DCC functionality on a DCC layout, and dual speakers for robust audio. Quick Plug plug-and-play technology with a 21-pin NMRA connector ensures easy DCC installation.

Prototype-informed details include road-number-specific nose doors (with or without windows), front ditch lights, and EOTD placement, along with an authentic UP paint scheme and related road-number features. The Genesis driveline combines a five-pole skew-wound motor, all-wheel drive, precision gears, and reliable electrical pickup for smooth operation on HO tracks, with RP25-contoured wheels for compatibility across brands. Designed for HO layouts with a minimum radius of 18 inches (22 inches recommended), this model serves as a striking, ready-to-run centerpiece for Union Pacific rosters.
