HO SD40 Locomotive Colorado & Southern #878 (ATH87234)

HO Scale Colorado & Southern SD40 Locomotive — a detailed, ready-to-run replica of the Colorado & Southern's SD40 fleet for HO layouts. The model captures authentic prototype styling with chicken wire radiator grills, MU hoses, and a rear pilot-mounted handbrake, along with see-through dynamic brake and cab windows. It is powered by an upgraded 5-pole skew-wound can motor with flywheels for smooth, quiet operation and is DCC-ready with Quick Plug plug-and-play technology, making it easy to upgrade for digital operation or run on DC layouts right away.

On the rails, it rides on RP25-contoured wheels and flexible Flexicoil-C trucks, with details like McHenry scale knuckle couplers for reliable coupling. The locomotive is offered as a fully assembled, ready-to-run model, with options for non-sound and Tsunami2 sound-equipped versions—sound models include onboard DCC/Sound with dual cube speakers and operate on both DC and DCC. A CV chart is included for tuning performance and lighting, and the design is suited to standard HO layouts with a minimum 18" radius (22" recommended) to ensure smooth, trouble-free operation.
