HO Scale SD70M Locomotive — Primed for Grime edition, ex-NS 2636. This weathered model reproduces the look of in-service locomotives, with faded base colors designed as a ready-made starting point for adding grime and rust. It captures the SD70M’s modern freight silhouette with prototype-style detailing to fit a realistic HO roster.

Designed for HO operation, the model rides on a heavy die-cast frame for traction and features RP25-contoured wheels for smooth performance on common HO track. It includes LED lighting, see-through cab windows with a full interior, and body-mounted scale McHenry knuckle couplers compatible with Kadee. The DCC-ready Quick Plug 21-pin NEM system enables easy decoder installation, and sound-equipped variants offer onboard Tsunami2 sound that can operate in both DC and DCC modes. The Primed for Grime finish provides a faithful starting point for adding weathering, and minimum radius is 18 inches (22 inches recommended) for reliable operation on typical layouts.
