HO GP7 Locomotive with DCC and Sound, AMTK #776 (ATHG-1248)

An HO-scale GP7 Locomotive with DCC and Sound, AMTK 776, is a precise, high-detail recreation of EMD’s GP7 diesel switcher. It rides on a heavy die-cast frame with a Genesis driveline and a 5-pole skew-wound motor for solid pulling power and smooth, quiet operation. LED lighting illuminates the model, and see-through cab windows reveal a full cab interior. Fine-scale Celcon handrails, etched radiator and fan grilles, and a detailed fuel tank with fillers and gauges add realism, while body-mounted scale knuckle couplers are Kadee-compatible and RP25 wheels ensure smooth performance on most tracks. The design is DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector, and it can run on DC or DCC; the sound-equipped version includes an onboard DCC decoder with SoundTraxx Tsunami2 and dual speakers for authentic engine, horn, and bell sounds.

Designed for HO-layout enthusiasts, this GP7 is built from prototype resources to match authentic paint schemes and detailing. It features Blomberg-B trucks with bearing caps, an accurately detailed fuel tank, roof features including hatches on non-dynamic units, and trainline/MU hoses along with coupler cut levers for added realism. With an 18-inch minimum radius, it delivers reliable operation on typical layouts, and CV-based tuning allows full DCC functionality and MU lashup programming (lead-unit horn, bell, and lights). The packaging protects the model during storage, making this a compelling, prototype-faithful centerpiece for any HO-scale roster.
