HO-scale GP38-2 diesel locomotive in CSX Ex-SBD Primed For Grime finish, road number 2623. This model captures the look of an in-service freight locomotive, with weathered base colors and patchwork CSX markings that make it a natural starting point for adding grime and rust to taste.

Built for authentic operation, the GP38-2 features a heavy die-cast frame for traction, a Genesis driveline with a 5-pole motor and precision flywheels, and fine detailing such as see-through cab windows, full cab interior, windshield wipers, coupler cut levers, MU hoses, trainline hoses, and LED lighting. It uses a DCC-ready Quick Plug 21-pin NEM connector for easy digital conversion, with RP25 wheel contours to match HO track brands and body-mounted scale knuckle couplers for prototypical coupling. Sound-equipped variants include a Tsunami2 onboard decoder with dual speakers, delivering engine, horn, and bell sounds in both DC and DCC modes, with full NMRA-compatible functions when in DCC. The model is designed to scale from prototype references—from paint and lettering to gear detail—with features like Celcon handrails, a detailed fuel tank, walkways, and an 18-inch minimum radius for smooth operation. Road-number-specific CSX Ex-SBD patches help achieve a faithful, ready-to-run representation of this weathered CSX unit.
