HO GP39-2u Locomotive ATSF #3418 (ATHG66254)

HO GP39-2u Locomotive ATSF #3418 is an HO-scale recreation of Santa Fe’s GP39-2u upgrade program, designed for model railroaders who value prototype-accurate detailing. This road-numbered model features a Phase 1 body with corrugated grilles, a rear-mounted fuel tank, switcher-style walkways, illuminated swing-out number boards, and a Stratolight beacon that lights in DCC-enabled setups. For #3418, a Nathan 3-chime horn and an access door behind the cab complete the prototype profile.

Under the hood, the locomotive delivers authentic performance with a Genesis-style drive, five-pole motor, and full cab interior visible through see-through windows. Realistic detailing includes fine-scale Celcon handrails, etched fan grilles, and body-mounted, Kadee-compatible knuckle couplers, all on a heavy die-cast frame for solid pulling power. The model is DCC-ready with Quick Plug and a 21-pin NEM connector, features LED lighting and reliable all-wheel pickup, and carries RP25-wheel contours for smooth operation on standard track. Optional sound-equipped variants include a Tsunami2 decoder with dual speakers and full DCC functionality, offering authentic engine, horn, and bell sounds that work on both DC and DCC, with a minimum radius of 18 inches.
