HO EMD SD40-2 Locomotive BN #8102 (ATH-1236)

HO-scale EMD SD40-2 locomotive in Burlington Northern livery, road number 8102, is a fully assembled, ready-to-run model designed for HO layouts. It captures the Dash-2 era with a heavy die-cast frame, a 5-pole motor, and all-wheel drive for smooth, quiet operation and solid pulling power. Prototypical detailing includes LED headlights and bi-directional front and rear lighting, ditch lights and beacons where applicable, see-through cab windows, flexible MU hoses and trainline hoses, wire grab irons, a detailed fuel tank with gauges and breather pipes, and photo-etched windshield wipers for a lifelike on-the-rails appearance.

Two configurations are offered: a DCC-ready, non-sound version with a 21-pin NEM socket for easy DCC installation, and sound-equipped variants that include an onboard DCC decoder with a single speaker. In DC or DCC, the sound-equipped models deliver engine, horn, and bell sounds, with NMRA-compatible CVs for advanced tuning; some functions may be limited in DC mode. The locomotive rides on RP25-contoured wheels with reliable current pickup and a heavy frame for traction and pulling power, and it is designed for HO layouts with a minimum recommended radius of 18 inches (22 inches preferred) to ensure smooth curves and dependable operation around the layout.
