HO RS-3 Locomotive SOU #6222 (ATH-2145)

HO-scale RS-3 Locomotive in Southern Railway livery, road number 6222, is a detailed, ready-to-run model of the ALCO RS-3 diesel-electric locomotive. It’s designed for HO-layout enthusiasts who want authentic mid-century motive power with reliable operation on their layouts.

It features a powerful, quiet can motor and all-wheel drive for smooth performance, along with DCC-ready Quick Plug 21-pin NEM compatibility and Econami sound options with a cube speaker on sound-equipped versions. Realistic touches such as LED lighting, see-through etched radiator fans and cab windows, metal grab irons, and fine-scale handrails sit on a heavy die-cast frame with RP25 wheels for authentic proportions and traction. The model is fully assembled and ready to run, with an 18-inch minimum radius (22 inches recommended); a CV chart is included to support NMRA-style adjustments and multi-unit lashups.
