HO GEN SD50 Locomotive CSXT YN2 #8563 (ATHG-1840)

Introducing the HO Genesis EMD SD50 locomotive in CSX livery, an HO-scale model from Athearn Genesis designed for serious hobbyists and layout operators. This reproduction captures the 3,500-horsepower SD50’s distinctive silhouette and power, translating the prototype into a detailed, ready‑to‑run model. From new tooling with correct door placements and weld marks to a longer hood, the model delivers Genesis‑level detailing, including a full cab interior, see‑through cab windows, windscreen wipers, and scale handrails. LED headlights, operating ditch lights, and working number boards add to the authentic appearance, while a heavy die‑cast frame provides realistic weight and traction. It’s compatible with both DC and DCC layouts and ready for easy sound installation if desired.

On the rails, the SD50 is built for flexible operation and faithful performance. It uses Quick Plug plug‑and‑play technology with a 21‑pin NEM connector for straightforward DCC conversion and sound installation; sound‑equipped variants feature Tsunami2 sound with dual speakers for rich horn, bell, and locomotive noises, plus NMRA‑compliant functions for reliable control. Road‑name refinements reproduce CSX era cosmetics such as repaint details, upper body placement, and class‑light plates on both ends, delivering an authentic CSXT appearance with period‑accurate horns and antennas. The model also features all‑wheel drive for smooth, quiet operation, Celcon handrails, walkways, and MU hoses, and a 22‑inch minimum radius to ensure it runs well on a wide range of HO layouts.
