HO SD70M Locomotive UP #4354 (ATHG-1590)

HO Scale SD70M Locomotive — Union Pacific #4354. This HO model faithfully reproduces EMD’s SD70M with a heavy die-cast frame for traction and a Genesis driveline that delivers smooth, quiet pulling power. It features a see-through cab with a full interior, body-mounted McHenry scale knuckle couplers (Kadee compatible), LED headlights, and RP25 wheel contours for reliable operation on common HO track. DCC-ready with Quick Plug plug‑and‑play technology and a 21-pin NEM connector, it’s built for easy digital upgrades, while all-wheel electrical pickup supports dependable DC or DCC performance on your layout.

For the UP #4354 road-number variant, the model carries authentic detailing such as flat radiators, a non-standard K5LA horn, and PTC antennas, finished in a Union Pacific repaint with flag and Building America branding for a faithful prototype look. It features a heavy-duty die-cast frame, a 5-pole skew-wound Genesis driveline with precision flywheels, and scale handrails that enhance realism. Sound-equipped versions include an onboard DCC decoder with SoundTraxx Tsunami2 sound, delivering engine, horn, and bell sounds that operate in both DC and DCC with full NMRA function control and CV customization for MU lashups. The locomotive is designed to run on minimum 18" radius curves (22" recommended) and serves as a compelling centerpiece for modern-era freight on a model railroad setup.
