HO EMD SD9043MAC Locomotive with DCC & Sound, CPR #3712 (ATHG27381)
HO scale EMD SD9043MAC Locomotive with DCC & Sound in CPR 3712 livery is a detailed, ready-to-run model that recreates CP’s patchwork ex-UP power from a former Union Pacific SD90MAC. This unit carries CP lettering over its UP heritage, reflecting CP’s 2021 program to patch a small batch of ex-UP locomotives into service. It features a Nathan 3-chime horn, a large EMD plow, front ditch lights, and illuminated ground lights and number boards for realistic operation day or night, with the faded base paint visible beneath the CP patches.
Under the hood, the model offers modern performance and detail: DCC-ready Quick Plug 21-pin NEM compatibility, onboard DCC decoder with SoundTraxx Tsunami2 sound, and dual cube speakers for full, authentic diesel audio. It rides on a heavy die-cast frame with eight-wheel drive and all-wheel electrical pickup for smooth, powerful operation, while RP25 wheel contours ensure compatibility with popular track. Realistic touches include see-through cab windows and a full cab interior, etched walkway steps, windscreen wipers, scale Celcon handrails, and LED lighting for ground lights and number boards; the model ships fully assembled and ready to run, and it’s primed for grime to help weather it to a prototypical finish.
