HO GEN SD90MAC Locomotive with DCC and Sound, SLRG Iowa Pacific Holdings #111 (ATHG-1942)

HO-Scale SD90MAC Diesel Locomotive with DCC and Sound — SLRG Iowa Pacific Holdings #111. This ready-to-run HO model recreates EMD’s high-powered SD90MAC for HO layouts, faithfully representing the SLRG unit #111. It includes a built-in DCC decoder and SoundTraxx Tsunami2 sound with dual speakers for authentic engine, horn, and bell audio that works in both DC and DCC modes, with 21-pin NMRA plug-and-play connectivity for easy decoder upgrades.

Built around a heavy die-cast frame for traction and pulling power, the locomotive features LED headlights, ground lights, etched see-through steps, a full cab interior, and fine-scale Celcon handrails for realism. Road-number-specific detail options, including nose-door variations, and patches to mirror prototype schemes add authenticity, while RP25 wheels ensure smooth operation on common HO tracks. Minimum radius is 18 inches (22 inches recommended), and the model supports full DCC functionality and easy lashups with other locomotives for versatile operation on an HO layout.
