HO SD70M Locomotive Union Pacific Flared #4855 Plastic Model (ATHG71117)

HO-scale Union Pacific SD70M Locomotive with Flared Radiator, road number 4855. This detailed UP model captures the distinctive SD70M look, including a white cab roof, GPS dome, antennas, round ditch lights, and a two-panel flared radiator body. Offered in three road numbers to diversify a UP roster, it’s a realistic centerpiece for any HO-scale layout, ideal for operating sessions or display.

Under the hood, the model features a Genesis driveline with a five-pole motor, precise flywheels, and a multi-link drivetrain for smooth, quiet pulling power. A heavy die-cast frame adds traction, while all-wheel electrical pickup and RP25-contoured wheels ensure reliable running on HO track. LED lighting, see-through cab windows, and a full cab interior heighten realism, while body-mounted McHenry scale knuckle couplers (Kadee-compatible) provide prototypical coupling. DCC-ready Quick Plug technology with a 21-pin NEM connector makes it easy to install on modern layouts, and sound-equipped versions add Tsunami2 sound that works on both DC and DCC. The model is prototype-accurate, drawn from measurements and photos, and specifies an 18-inch minimum radius with 22 inches recommended for the best performance.
