HO EMD SD39 Locomotive with DCC and Sound, SP #5317 (ATH-1461)

HO-scale EMD SD39 diesel locomotive with DCC and sound recreates a Southern Pacific six-axle freight powerhouse for HO layouts. The model features a detailed injection-molded body, see-through cab windows, fine-scale handrails, and SP-specific details such as a 3600-gallon fuel tank, FARR radiator grilles, large ballast boxes, and front/rear EMD plows. A heavy die-cast frame and precise gearing deliver smooth, quiet pulling power, while SP lighting with Gyralights adds authentic signaling. The design supports 18-inch minimum radius, with 22 inches recommended for best performance.

Sound-equipped variants use onboard Econami Sound by SoundTraxx, providing engine, horn, and bell sounds that operate in both DC and DCC, with full DCC functionality when used in DCC mode. LED headlights and ditch lights, RP25-contoured wheels, and McHenry scale knuckle couplers enhance realism, and the model includes see-through dynamic brake and radiator fans for extra detail. The SD39 lineage comes from late-1960s EMD six-axle designs delivering about 2,000 horsepower. For weathering enthusiasts, primed-for-grime versions offer a ready starting point with base colors matched to the prototype for easy grime and rust work. The model arrives fully assembled and decorated, ready to run on HO layouts.
