HO AC4400CW Locomotive with DCC and Sound CP #8621 (ATHG-2063)

HO-scale Athearn Genesis GE AC4400CW diesel locomotive in CP’s Golden Beaver scheme, numbered 8621, designed to deliver a modern freight unit with authentic DCC and sound. This model includes an on-board DCC decoder with Tsunami2 sound and dual speakers, offering lifelike engine, horn, and bell performance with NMRA-compatible functionality for smooth operation on both DC and DCC layouts. Prototypical features shine through with carefully painted and printed livery, illuminated number boards, rear and walkway lighting, ground lights, and a see-through cab with a detailed interior.

Built on a heavy die-cast frame with a Genesis drivetrain and a 5-pole skew-wound motor, it provides smooth, quiet operation and strong pulling power. Prototypical details include GE self-steering trucks, Sinclair antennas, anticlimber front ditch lights, and low-mounted number boards, complemented by realistic cab and exterior touches to enhance authenticity. The model is best suited to layouts with an 18-inch minimum radius (22 inches and larger recommended) to ensure reliable performance and an optimal appearance on typical modern layouts.
