HO-scale Athearn Genesis EMD SD90MAC diesel locomotive in CEFX 106 livery is a faithful, fully assembled representation of the prototype designed for serious HO-scale operations. This ready-to-run model captures the SD90MAC’s imposing presence with a heavy die-cast frame, meticulous detailing, and realistic lighting, including working number boards and ground lights, etched see-through steps and cab windows, windshield wipers, and LED headlights to bring the unit to life on the layout. DCC-ready with Quick Plug technology and a 21-pin NEM connector makes it straightforward to add decoders or sound, while the full cab interior and fine scale handrails contribute to an authentic, magazine-worthy appearance.

Across the rails the SD90MAC model delivers authentic operation. The Genesis driveline uses a 5-pole skew-wound motor, precision flywheels, and a multi-link drivetrain for smooth, powerful pulling, with all-wheel drive and all-wheel electrical pickup for reliable current flow. RP25-contoured wheels, LED lighting, and body-mounted scale knuckle couplers create a realistic silhouette and dependable performance on typical HO track. The model also offers prototype cues such as nose-door options and front ditch lights, with Legendary Liveries providing iconic paint schemes for collectors. Sound-equipped versions feature onboard DCC decoders with Tsunami2 sound, dual speakers, and NMRA-compatible CVs for fine-tuning; grime-ready finishes let modelers recreate years of service. For layout planning, a minimum radius of 18 inches is recommended, with 22 inches or more preferred for smooth travel around curves and through yards.
