HO GP15-1 Locomotive Rock Island Rail #1106 (ATHG13245)

HO Scale GP15-1 Locomotive in Rock Island Rail livery, #1106, is a ready-to-run model that captures the look of a classic four-axle diesel yard switcher. Officially approved by Rock Island Rail, it features period-accurate touches inspired by an ex-CNW 4411, including a relocated bell, M-3 horn, UP-style front plow, Sinclair and Can antennas, and front and rear ditch lights.

Built on a Genesis driveline inside a heavy die-cast frame, this GP15-1 delivers solid pulling power and smooth operation with a 5-pole skew-wound motor, precision flywheels, and a multi-link drivetrain. It rides on RP25-contoured wheels for reliable tracking on HO track and includes LED lighting, a full cab interior with see-through windows, walkways, windshield wipers, lift rings, and scale handrails. The locomotive is DCC-ready with Quick Plug 21-pin NEM wiring, and some versions offer onboard SoundTraxx Tsunami2 sound with dual speakers for authentic engine and horn effects; CV changes and a chart let enthusiasts tailor performance. Minimum operating radius is 18 inches, with 22 inches recommended for best results on typical HO layouts.
