HO GEN SDP45 Locomotive SP #3201 Plastic Model (ATHG-1995)

HO Scale SDP45 Diesel Locomotive in Southern Pacific livery, SP 3201. This ready-to-run model from Athearn faithfully recreates the SDP45’s long-hood profile and the steam-generator-era styling that defined the prototype for mid-century passenger service.

Designed for HO layouts, the model features a DCC-ready Quick Plug 21-pin interface, LED lighting, a full cab interior, detailed fuel tank, and fine-scale Celcon handrails with body-mounted McHenry knuckle couplers. The Genesis driveline delivers smooth, quiet operation via a 5-pole motor and all-wheel drive, with RP25-contoured wheels for reliable running on popular HO track. Sound-equipped versions add onboard Tsunami2 sound with dual speakers for authentic engine, horn, and bell sounds. Road-number-specific details include SP 3201’s fresh red/grey repaint, and the model is scaled from prototype resources with accurately painted schemes. It is fully assembled and ready to run on layouts with an 18-inch minimum radius (22 inches recommended).
