HO GEN AC4400CW Locomotive CP #8621 (ATHG-2045)
Athearn Genesis GE AC4400CW Diesel Locomotive in CP's Golden Beaver livery, CP 8621. This HO-scale model faithfully reproduces GE's AC4400CW, capturing the modern freight locomotive’s silhouette and a host of prototype details—from authentic paint and illuminated number boards to a full cab interior. It’s designed for flexible control, with DCC-ready Quick Plug 21-pin NEM connectors, and is available in sound-equipped versions featuring Tsunami2 sound and dual speakers for immersive layout operation.
Inside, a heavy die-cast frame houses a Genesis drive system with a five-pole skew-wound motor, precision flywheels, and a multi-link drivetrain for smooth, quiet pulling power. Features include all-wheel drive and electrical pickup, RP25-contoured wheels for broad track compatibility, and McHenry scale knuckle couplers for reliable operation. Prototypical detailing spans etched walkways, see-through cab windows, and a full cab interior, along with CP touches such as Sinclair antennas and GE self-steering trucks. For layout planning, the model requires a minimum 18" radius (22" is recommended) to ensure optimal performance on typical HO layouts.
