HO SD40T-2 Locomotive SP/Kodachrome #8315 (ATH73047)

HO scale Southern Pacific Kodachrome SD40T-2 tunnel-motor locomotive in the mid‑1980s Kodachrome scheme captures the bold SP/Santa Fe-inspired repaint and is designed for use on HO model layouts. This model covers three road-number variants—8315, 8351, and 8377—each with small, era‑appropriate detail differences in nose length, bell placement, plow configuration, and lettering, reflecting the distinctive “snoot-nose” tunnel-motor look from that period.

Designed for authentic operation, the model features fine‑scale handrails, see‑through radiator grilles and dynamic brakes, separately applied air tanks, LED lighting with Gyra lights that operate in DCC, cab roof A/C, and a P3 horn with see‑through lower air intakes. It rides on nickel‑plated, blackened machined wheels with RP25 contours for reliable track performance and comes fully assembled and ready to run. The base model is DCC‑ready with a 21‑pin NEM Quick Plug, while sound‑equipped versions include Tsunami2 sound with full DCC functionality and realistic engine, horn, and bell sounds; many functions are NMRA‑compatible with DC operation as well. The six‑axle GM‑EMD 645E3 engine models 3,000 horsepower, and the model includes McHenry operating knuckle couplers and all‑wheel drive for smooth, quiet operation on HO layouts. A 22‑inch minimum curve radius is recommended for optimal operation.
