HO GP39-2u Locomotive with DCC & Sound ATSF #3418 (ATHG66354)

HO-scale GP39-2u Locomotive with DCC & Sound — Santa Fe #3418 — is a detailed model that recreates Santa Fe’s mid-1980s GP39-2u rebuilds. It features a PH 1 body with corrugated grilles, a rear-mounted fuel tank, and a newly tooled exhaust stack, along with switcher-style walkway steps and an equipment door behind the cab. Road-number-specific details for #3418 include a Nathan 3-chime horn and illuminated swing-out number boards, with a Stratolight beacon providing a subtle lighting effect in DCC, plus lit number boards and class lights for nighttime realism. See-through cab windows reveal a full cab interior, enhancing the operating experience.

Under the shell, the GP39-2u uses a Genesis driveline with a 5-pole skew-wound motor for smooth, quiet operation, backed by a heavy die-cast frame for traction. All-wheel electrical pickup and RP25-contoured wheels ensure reliable running on HO track, while body-mounted scale knuckle couplers provide prototypical coupling. The model is DCC-ready with Quick Plug technology and a 21-pin NEM connector and includes onboard SoundTraxx Tsunami2 sound with dual speakers that operate in both DC and DCC. It supports full DCC functions, can be used in MU lashups, and has a minimum 18-inch radius for layout compatibility.
