HO GP7u Locomotive with DCC and Sound, CKRY #701 (ATHG-1499)

This HO-scale GP7u locomotive with DCC and sound, CKRY #701, is a precisely detailed model built to bring the look and feel of a Santa Fe GP7 rebuild to an HO layout. It captures the GP7’s compact, rugged silhouette with see-through cab windows and a full cab interior, plus etched radiator grilles, scale handrails, and a heavy die-cast frame for traction. LED lighting adds realism, and RP25 wheels with all-wheel-drive gearing deliver smooth, quiet operation on standard HO track. The DCC-ready Quick Plug technology with a 21-pin NEM connector keeps installation straightforward, while DC operation remains possible for mixed-layout use.

Road-number specifics for CKRY #701 include a cab-mounted headlight, a large firecracker antenna with ground plane, and roof-mounted air tanks. CKRY-specific features add four exhaust stacks and a Leslie S-3L-R horn for an authentic prototypical presence. The sound-equipped variant houses a SoundTraxx Tsunami2 onboard decoder with dual speakers, delivering engine, horn, and bell sounds plus precise slow-speed control and full DCC functionality. It supports MU lashups and CV adjustments (CV chart included) and, with an 18-inch minimum radius, offers reliable, smooth performance on most HO layouts.
