HO SD40 Locomotive with DCC and Sound Undecorated (ATH73747)

HO Scale SD40 Locomotive with DCC and Sound in an undecorated shell is a detailed HO‑scale diesel model that faithfully captures the look and operation of the EMD SD40. It includes an onboard DCC decoder and SoundTraxx Econami sound for authentic engine and horn effects, while the undecorated body provides a blank canvas for custom paint schemes or weathering on your roster. Built for HO layouts, it’s designed to deliver smooth, reliable performance on standard HO track and serves as a versatile platform for both display and operation.

In terms of detail and compatibility, the model features LED lighting, see‑through cab windows, photo‑etched windshield wipers, and fine‑scale handrails, along with a detailed 4000‑gallon fuel tank and dynamic brake components. It rides on Flexicoil‑C trucks with RP25 wheel contours, uses McHenry scale knuckle couplers (Kadee compatible), and offers all‑wheel drive with precise gearing for quiet operation. The version with sound includes an onboard DCC decoder with SoundTraxx Econami sound and a single cube speaker; sound functions operate in both DC and DCC, with full NMRA‑compliant functionality in DCC and configurable options via CVs (CV chart included). A minimum 18" radius is recommended (22" for best results).
