HO EMD SD39 Locomotive Southern Pacific #5313 (ATH-1452)

HO Scale EMD SD39 Locomotive, Southern Pacific 5313, is a highly detailed model designed for authentic operation on HO layouts. It captures the prototype’s distinctive look with a front and rear SP lighting package featuring gyralights, a 3600-gallon fuel tank with dual fillers, FARR radiator grilles, and large ballast boxes. Front and rear EMD plows, dynamic brakes, rear walkway brakes, a cab roof bell, and an L-style front window contribute to an era-accurate silhouette, while see-through cab windows and visible radiator and brake components add realism. Available in sound-equipped and non-sound configurations, it’s DCC-ready with a 21-pin NEM plug and arrives fully assembled, painted, and decorated for immediate operation. It is built for HO layouts with an 18-inch minimum radius (22 inches recommended) and offers weathering-ready options such as Primed for Grime finishes.

Under the shell, the SD39 features a heavy die-cast frame for traction and stability, driven by a 5-pole motor with flywheels and a multi-link drive train for smooth, quiet operation. All-wheel electrical pickup, RP25-contoured wheels for compatibility with popular HO tracks, and McHenry scale knuckle couplers deliver reliable performance and realistic handling. The model includes fine-scale handrails, separately applied detail parts, and see-through dynamic brake and radiator fans for added authenticity. Sound-equipped versions showcase Onboard Econami Sound by SoundTraxx with full DCC functionality, engine and horn sounds, and advanced slow-speed control, while non-sound variants support DC/DCC operation via a 21-pin plug. Genesis motor retrofit compatibility provides upgrade options, making this SP SD39 a versatile addition to any HO fleet. Minimum radius remains 18 inches with 22 inches recommended, and Primed-for-Grime finishes offer a ready starting point for weathering enthusiasts.
