HO GEN AC4400CW Locomotive CP Dual Flags #8638 (ATHG-2046)

HO-scale GE AC4400CW diesel locomotive in Canadian Pacific Dual Flags livery. This Athearn Genesis model captures the look and feel of GE’s heavy-haul locomotive and is designed for realistic operation on HO layouts. It’s DCC-ready with Quick Plug 21-pin NEM interface and features accurate, printed graphics, LED lighting with illuminated number boards, and front and rear walkway lights to reproduce the prototype’s nighttime visibility, along with see-through cab windows and a full cab interior for an authentic interior view.

On the rails, the locomotive emphasizes performance and durability: a heavy die-cast frame for traction, Genesis driveline with a five-pole skew-wound motor, precision flywheels, and a multi-link drivetrain for smooth, quiet running. All-wheel electrical pickup, RP25-contoured wheels, and McHenry scale knuckle couplers ensure reliable operation and compatibility with a wide range of HO rolling stock. Fine-scale Celcon handrails, etched walkway steps, a detailed fuel tank, and a realistic ground lighting option enhance realism, while a minimum 18-inch radius (22 inches recommended) keeps it track-friendly on common layouts. Road-number-specific details reflect prototype variations, and sound-equipped versions add onboard DCC decoding with SoundTraxx Tsunami2, dual speakers, and full NMRA functions for operating in both DC and DCC modes, with CVs available to tailor performance.
