HO GP38-2 Locomotive Union Pacific Baby Wings Yellow Sill #594 (ATHG-1398)

HO-scale GP38-2 diesel locomotive in Union Pacific's Baby Wings with Yellow Sill livery, UP 594. This model is designed for authentic operation on HO layouts, delivering the look and feel of late-20th-century UP power for mainline runs, switching duties, or display.

It combines modern operation with classic detailing, featuring a DCC-ready Quick Plug 21-pin NEM interface, full cab interior, see-through cab windows, LED lighting, and a heavy die-cast frame for traction. RP25-wheel contours and body-mounted scale knuckles ensure smooth tracking and prototypical coupling, while fine Celcon handrails, a detailed fuel tank, MU hoses, walkways, and other period-correct touches heighten realism. Sound-equipped variants add onboard DCC with SoundTraxx Tsunami2 and dual speakers for authentic engine, horn, and bell sounds, with NMRA-compatible functions and CV-based control for lashups. The model suits HO layouts with an 18-inch minimum radius, delivering reliable operation and striking UP presence.
