HO SD40 Locomotive Western Maryland #7448 (ATH87231)

HO Scale SD40 Locomotive in Western Maryland livery, number 7448. This ready-to-run HO model reproduces the 3,000-horsepower EMD SD40 six-axle locomotive, offering an authentic Western Maryland representative for operating on a home or club layout.

Designed for realistic performance, the model features bi-directional LED lighting, see-through dynamic brake and cab windows, and fine-scale handrails, plus a 4,000-gallon fuel tank and McHenry scale knuckle couplers compatible with Kadee. It rides on Flexicoil-C trucks with high brake cylinders and RP25-contoured wheels for smooth operation on common tracks. A newly designed can motor delivers stronger, quieter power, and DCC-ready Quick Plug plug-and-play enables easy digital upgrades; sound-equipped versions include an onboard Tsunami2 DCC/Sound decoder with dual cube speakers for authentic engine, horn and bell sounds and operate on both DC and DCC, with NMRA-compatible function control. The model supports multi-unit lash-ups and features prototype detailing, with a minimum radius of 18 inches (22 inches recommended for best performance).
