HO GEN AC4400CW Locomotive w/DCC & SOUND Canadian Pacific 'Dual Flags' #8638 (ATHG-2064)

HO-scale GE AC4400CW diesel locomotive with DCC and sound in Canadian Pacific “Dual Flags” livery, road number 8638. This highly detailed model recreates a modern mainline powerhouse, offering DCC-ready operation via a 21-pin NEM connector and an onboard SoundTraxx Tsunami2 sound system paired with dual cube speakers for authentic engine, horn, and bell effects. Realistic lighting includes illuminated number boards, ground lighting above the front truck, front and rear walkway lights, and marker lights, while see‑through cab windows reveal a full cab interior. The Genesis driveline combines a 5-pole skew-wound motor, precision flywheels, and a multi‑link drivetrain mounted on a heavy die-cast frame for smooth, quiet performance and strong pulling power. McHenry scale knuckle couplers are Kadee-compatible, with flexible MU hoses and a trainline hose to recreate realistic lashups, and the model runs on both DC and DCC with full DCC functions and configurable CVs for advanced control.

Designed for HO layouts, this CP Dual Flags AC4400CW brings a commanding presence to modern-era scenes. It rides on RP25 wheels for broad track compatibility, features a meticulously painted CP scheme with road-number touches, and is primed for grime to support weathering for a weathered, “In Service” look. The combination of a heavy frame, all‑wheel electrical pickup, and faithful detailing delivers dependable traction and a believable, high‑powered feel as it hauls freight across the layout. With an 18-inch minimum radius and 22-inch or larger curves recommended, it fits a wide range of layouts, and its DC‑and‑DCC operation, plus CV programming for MU lashups, makes it easy to integrate into existing fleets.
