HO GEN GP7 Locomotive Southern Railway SOU #8248 (ATHG-2281)

An HO-scale EMD GP7 diesel locomotive modeled after Southern Railway’s 8248, this unit captures the 1949 GP7 look with a short hood and a full-height hood housing the engine and mechanical components. The model features see-through cab windows, a detailed fuel tank with fillers and gauges, etched radiator grilles, scale handrails, and a heavy die-cast frame for solid pulling power. It rides on period-accurate Blomberg-B or AAR Type-A trucks with precise gearing and RP25 wheel contours for reliable HO-track operation, complemented by LED lighting for a lifelike appearance. The DCC-ready Quick Plug interface uses a 21-pin NM connector, making layout operation simple on DC or DCC layouts, with sound-equipped variants offering Tsunami2 engine, horn, and bell sounds through dual speakers.

In the Southern SOU livery, the version features an 800-gallon fuel tank, sunshades, no dynamic brakes, cut skirts, and mixed wheel bearings to mirror prototype equipment. The GP7’s Genesis driveline uses a 5-pole skew-wound motor with precision flywheels and a multi-link drivetrain for smooth, quiet operation, plus all-wheel electrical pickup for dependable power on HO layouts with an 18-inch minimum radius. Road-number- and road-name-specific variations provide authentic detailing across schemes, while the model’s fine detailing invites weathering to recreate grime and wear for a truly era-accurate display.
