HO SD40-2 Locomotive with DCC & Sound, NS #3272 (ATH-1810)
This HO-scale Norfolk Southern SD40-2 locomotive with DCC and sound brings the power and detail of the prototype to your layout. Numbered 3272, it is fully assembled and ready to run, pairing a DCC decoder with SoundTraxx Econami on-board sound for engine, horn, and bell effects that operate on both DC and DCC layouts. A heavy die-cast frame, precise gearing, and all-wheel drive provide smooth, quiet pulling power, while RP25 wheel contours and McHenry scale knuckle couplers ensure reliable operation with standard HO rolling stock. Fine touches like see-through cab windows, wire grab irons, photo-etched windshield wipers, and LED headlights with ditch lights enhance realism.
Road-name specific details reflect NS heritage with practical authenticity, including a high short hood, bell mounted on the long hood, walkways with lighting, and a front/rear plow setup on DCC-equipped units. The model rides on a 4000-gallon fuel tank with detailed fuel fillers and breather pipes, built on a sturdy die-cast frame for stronger pulling power. It is designed for HO layouts with a minimum 18-inch radius (22 inches recommended) and offers NMRA-compatible DCC functionality; CVs can be adjusted for lashups and lighting, with a CV chart included to guide setup.
