HO GP39-2u Locomotive ATSF #3415 (ATHG66253)

HO Scale GP39-2u Locomotive — Santa Fe #3415. This upgraded GP39-2 rebuild is designed for HO model railroaders seeking an authentic Santa Fe prototype. It reproduces the mid-1980s GP39-2u with a phase 1 body and distinctive grille detailing, features like swing-out number boards, a rear-mounted fuel tank, and a new exhaust stack, along with switcher-style walkway steps and an access door behind the cab. A Stratolight beacon adds on-track realism in DCC operation and illuminated number boards enhance daytime visibility.

Built for faithful operation on HO layouts, this model combines a heavy die-cast frame, Genesis drive with a 5-pole motor and all-wheel drive for smooth, quiet performance. See-through cab windows reveal a full interior, while fine-scale Celcon handrails and etched fan grilles add realism. Lighting includes LED headlights, class lights, and beacons, with body-mounted knuckle couplers (Kadee-compatible) and RP25 wheels for scale-true presentation. DCC-ready Quick Plug wiring with a 21-pin NEM connector simplifies decoder installation, and sound-equipped variants feature Tsunami2 with dual speakers for operation in both DC and DCC, with a CV chart included for customization. A grime-ready option provides a weathering-friendly starting point, and the model is designed for an 18-inch minimum radius on HO layouts.
