HO EMD SD40-2 Locomotive with DCC and Sound, BN #8102 (ATH-1264)

An HO-scale EMD SD40-2 locomotive with DCC and sound that recreates Burlington Northern’s Dash 2 freight hauler on a model railroad. This fully assembled, ready-to-run model includes an onboard DCC decoder with SoundTraxx Econami sound and a single cube speaker for clear, authentic audio, and it runs on both DC and DCC. Engine, horn, and bell sounds are active in DC, with some functions limited, while DCC mode provides full function control and NMRA compatibility. Built on a heavy die-cast frame with all-wheel drive and a 5-pole motor, it delivers strong traction and smooth, quiet operation, aided by RP25-contoured wheels and bi-directional LED lighting for realistic appearances.

Detail is faithful to the prototype: see-through cab windows, flexible rubber MU hoses, coupler cut levers, wire grab irons, and an exhaust stack, plus see-through dynamic brake and radiator fans, a detailed fuel tank with gauges and breather pipes, and separately applied air tanks. Fine-scale Celcon handrails and photo-etched stainless-steel windshield wipers boost the scale look, while McHenry operating scale knuckle couplers ensure accurate coupling. Minimum curve radius is 18 inches, with 22 inches recommended for the best performance on tighter layouts, letting this SD40-2 handle yard runs or mainline runs with ease.
