HO SD70M-2 Locomotive Eastern Maine NBSR #6403 (ATHG75568)

An HO-scale SD70M-2 diesel locomotive reproducing the Eastern Maine/NBSR 6403 unit, this ready-to-run model brings a modern freight power to HO layouts. Built on the SD70M-2 platform, it uses a 16‑cylinder, 4300‑horsepower engine that drives an alternator and powers the traction motors, delivering authentic diesel-electric performance. The exterior captures late-era design cues such as a full-height nose door, rectangular windshields, and a large radiator package with two fans, with the dynamic braking equipment positioned behind the long hood and road-number lettering variations reflecting Maine Northern and Eastern Maine schemes.

For layout use, the model is DCC-ready with Quick Plug plug-and-play technology using a 21-pin NEM connector, making decoder installation straightforward. It features LED lighting, a full cab interior with see-through windows, etched steps, lift rings, lit number boards, and functional MU and trainline hoses, all mounted on a heavy die-cast frame for added traction. Scale handrails, a detailed fuel tank with fillers and breather pipes, and RP25 wheel contours enhance realism and reliability on common HO track. It runs smoothly on HO curves with a minimum radius of 18 inches (22 inches recommended), and road-name lettering options include Maine Northern and Eastern Maine schemes to match a roster.
