HO G2 SD90MAC-H Phase I with DCC & Sound UP #8509 (ATHG27325)

HO-scale Union Pacific SD90MAC-H Phase I locomotive with DCC and sound, road number UP 8509, designed for realistic operation on an HO layout. This model delivers authentic late-1990s UP power with a built-in DCC decoder and sound for immersive control and performance.

Notably, the UP 8509 unit is depicted with the starter capacitor removed and the End-of-Train beacon mounted further forward on the fuel tank, a detail associated with certain 8500-series units. The 8500-series represents the second and third orders delivered from 1997 to 1999 before their renumbering to the 8900 series, and Union Pacific was the sole buyer of these machines. Early examples were known to wear multiple numbers during pre-production, adding historical authenticity to a late-1990s UP roster piece.
