HO F7A / F3B Locomotive Set ACL #370 and #336-B (ATHG19586)

This HO-scale F7A / F3B Locomotive Set recreates Seaboard Coast Line’s ACL purple-and-silver freight power in road numbers 370 and 336-B. The two-unit pairing includes an F7A (A-unit) and an F3B (B-unit), featuring see-through cab windows, back-up lights, and period-correct detailing, finished in a distinctive purple livery with large Seaboard Coast Line lettering. It’s designed to add authentic freight power to HO layouts, pairing well with era-appropriate rolling stock for realistic operations.

Under the shell, the locomotives use a Genesis driveline with a five-pole skew-wound motor, a heavy die-cast frame for traction, and all-wheel drive with reliable electrical pickup for smooth, quiet operation on standard HO track. They are DCC-ready with Quick Plug 21-pin NEM connectors and body-mounted McHenry scale knuckle couplers for easy setup; sound-equipped variants add a Tsunami2 decoder with dual speakers for engine, horn, and bell sounds, operable in both DC and DCC. Prototypical detailing includes coupler cut levers, Trainline and MU hoses, windshied wipers, etched metal grilles, see-through cabs, LED lighting, and a detailed fuel system, while minimum 18-inch curves (22-inch recommended) ensure reliable operation on typical layouts.
