HO GP7u Locomotive with DCC & Sound, CKRY #903 (ATHG-1500)

An HO-scale GP7u locomotive with DCC and sound, CKRY #903. This highly detailed model captures the GP7u rebuild-era switcher with a heavy die-cast frame, all-wheel drive for smooth, quiet operation, and RP25 wheel contours that run well on standard HO track. Inside, a DCC decoder powers SoundTraxx Tsunami2 sound with dual speakers, delivering authentic engine rumble, horn blasts, and bell chimes whether you’re running on DC or DCC. From see‑through cab windows and etched radiator grilles to body-mounted couplers and precisely printed CKRY livery, it’s built to look right on a yard or mainline scene.

CKRY-specific styling includes four exhaust stacks and a Leslie S-3L-R horn with bracket to mirror the rebuild-era appearance. The GP7u is designed for easy DCC integration with a 21‑pin NEM plug and is compatible with layouts using standard 18-inch-radius curves. Road-number variations and prototype details are documented to support authentic lashups, while the durable construction and detailed finish make this model a capable centerpiece for switching work or through-traffic on an HO layout.
