HO G2 SD90MAC-H Phase I Locomotive Model UP #8500 (ATHG27224)

An HO-scale Union Pacific SD90MAC-H Phase I locomotive model designed to bring early UP power to life on a model railroad. This faithful replica recreates the Phase I SD90MAC-H units delivered in the late 1990s in Union Pacific livery, giving model railroaders a historically accurate centerpiece for an era-specific layout.

Part of the second and third orders of the SD90MAC-H delivered between 1997 and 1999 before a final renumbering to the 8900-series, this model captures the look and feel of that period. Some examples in this run were produced with the starter capacitor removed and the End-of-Train device relocated forward on the fuel tank, reflecting prototype detail variations. Ideal for HO layouts and collectors seeking era-appropriate UP power, it pairs with typical HO-scale rolling stock and track to create a convincing late-1990s scene.
