HO GP9 Locomotive #3777 (ATHG82726)

An HO-scale GP9 diesel locomotive reproduced as a Phase II GRIP rebuild, featuring a front SP full-light package, late-modified skirts, large end plows, and a long-hood air-filter box. This fully assembled model is ready to run on standard HO layouts, offering a prototypical look and proven reliability for mid-century switching scenes.

Beyond the shell, it delivers a wealth of scale details—full cab interior with see-through windows, etched radiator and fan grilles, wire grab irons, scale handrails, and RP25 wheels on Blomberg-B trucks for authentic appearance and smooth operation. It rides on a heavy die-cast frame for traction and includes DCC-ready Quick Plug with a 21-pin NEM connector for easy decoder upgrades, plus a Genesis driveline with a 5-pole motor for quiet, steady performance and precise slow-speed control. Lighting stays directional for realistic operation, and accurately painted schemes complete the prototype look. Some variants may include onboard DCC with Tsunami2 sound and dual speakers. For layout planning, a minimum recommended radius is 22 inches (18 inches minimum).
