Introducing the HO-scale SD70M Locomotive, Primed for Grime, representing ex-NS 2643. This weather-ready HO model is designed for weathering enthusiasts who want a convincing in-service appearance right out of the box. It features a heavy die-cast frame for traction, a see-through cab with a full interior, and body-mounted scale knuckle couplers for authentic operation. LED headlights, RP25 wheel contours for realistic tracking on HO layouts, and a DCC-ready Quick Plug 21-pin NEM connector make it easy to upgrade; sound-equipped variants include a Tsunami 2 onboard decoder delivering engine, horn, and bell sounds when used in DCC, with DC operation available as well.

Finished in the Primed for Grime scheme, this model recreates the faded base colors of in-service locomotives and provides an ideal canvas for weathering grime and rust. It reflects prototype-level detail drawn from extensive resources, including ex-NS 2643 road-number specifics and PRLX features such as a front plow, K5LAR24 horn, and flared radiators. The model rides on a Genesis driveline with a 5-pole skew wound motor, precision flywheels, and a multi-link drivetrain for smooth, quiet operation, with all-wheel electrical pickup for reliable power. It’s built for HO layouts with a minimum radius of 18 inches (22 inches recommended), making it a compelling weathering-focused centerpiece.
