HO G2 SD90MAC-H Phase I Model UP #8520 (ATHG27223)

Union Pacific Gen 2 SD90MAC-H Phase I locomotive for HO scale is a faithful recreation of UP's late Phase I high-horsepower freight locomotive, designed to bring authentic UP power to a model railroad layout.

Authentic historical details include Phase I variants where the starter capacitor is removed and the end-of-train device sits farther forward on the fuel tank; the model represents the second and third orders delivered between 1997 and 1999 before renumbering to the 8900-series. This late Phase I example is well suited for dioramas, mainline runs, or UP-focused layouts, offering a precise touch of UP history to any HO-scale collection.
