HO SD60M Tri-Clops Locomotive Union Pacific #2257 (ATHG75532)

An HO-scale Union Pacific SD60M Tri-Clops Locomotive, designed to bring authentic modern UP freight power to HO layouts. This road-number–specific model replicates the distinctive Tri-Clops three-window cab and offers four paint variations, including a weathered “Grime” option to reflect in-service appearance for UP units such as 2257, 2285, 2365, and 2367.

The locomotive delivers realistic operation and detail, with lit number boards and class lights, front ditch lights, and see-through cab windows with a full interior. A heavy die-cast frame provides traction, supported by RP25 wheel contours for smooth running and McHenry knuckle couplers for prototypical coupling. DCC-ready Quick Plug 21-pin NEM compatibility is available, and some versions include Tsunami2 sound with dual speakers for authentic engine, horn, and bell effects. Minimum radius is 18 inches (22 inches recommended) to ensure smooth operation on common layouts.
