HO Genesis SD50 Locomotive CSXT YN2 #8556 Plastic Model (ATHG-1839)

HO Genesis EMD SD50 Locomotive in CSXT YN2 #8556 livery is an HO-scale model built for serious model railroading. It faithfully recreates EMD’s 3,500-horsepower SD50 transition locomotive from the early 1980s, with authentic door placements, weld marks, and a detailed cab interior. The CSX Huntington repaint on #8556 captures the distinctive look, including black anticlimbers and CSX body placement. Available in DCC-ready form or with Tsunami2 sound in certain configurations, the model uses a 21-pin NEM connector for easy DCC upgrades.

Designed around a heavy die-cast frame and Genesis drivetrain, it delivers smooth, quiet operation and strong pulling power, with all-wheel electrical pickup and RP25 wheel contours for reliable performance. Realistic features include LED headlights, operating number boards, see-through cab windows, and prototype-specific detailing such as antennas, horns, and bells. The model supports DC and DCC, with plug-and-play options for quick digital upgrades, and is optimized for layouts with a 22-inch minimum radius.
