HO F3A Locomotive Southern Pacific #6105 (ATHG19576)

HO-scale Southern Pacific F3A Locomotive, SP 6105. This finely detailed model faithfully recreates EMD’s Phase II F3A for Southern Pacific freight service, making it a compelling centerpiece for an era-accurate HO layout. It captures signature features such as slot-style dynamic brakes, dual single-note horns on the A-unit, a freight pilot, and the era-typical grab irons and skirts.

Under the hood, a Genesis driveline—with a five-pole skew-wound motor, machined flywheels, and a multi-link drivetrain—delivers smooth, quiet operation and reliable power transfer. See-through cab windows reveal a full interior, and the model carries authentic detailing from etched metal grilles to a detailed fuel tank. LED lighting provides realistic headlights and markers, while RP25-contoured wheels and body-mounted McHenry scale knuckle couplers (Kadee-compatible) ensure dependable operation on HO track. It is DCC-ready with Quick Plug technology and a 21-pin NEM connector for easy decoder upgrades, and the minimum radius is 18 inches (22 inches recommended) for best performance. Sound-equipped versions add onboard DCC with SoundTraxx Tsunami2 and dual speakers, delivering engine, horn, and bell sounds that function in both DC and DCC modes with CVs to tailor lashups and lighting effects.
