HO EMD SD40-2 Locomotive with DCC and Sound KCS #681 (ATH-1259)

An HO-scale EMD SD40-2 locomotive with DCC and sound in KCS livery, road number 681, this model offers a detailed, ready-to-run representation of a classic Dash-2 freight locomotive for HO model railroad layouts.

Equipped with a SoundTraxx Econami onboard decoder and a single speaker, it delivers authentic engine, horn, and bell sounds that operate on both DC and DCC layouts, with full NMRA compatibility in DCC mode (some functions are limited in DC). The locomotive features a heavy die-cast frame for traction, all-wheel drive, and a five-pole motor with precision flywheels for smooth operation, along with prototypical detailing such as see-through cab windows, wire grab irons, photo-etched windshield wipers, and a detailed fuel tank with fuel fillers, gauges, and breather pipes. It includes McHenry operating scale knuckle couplers, RP25-contoured wheels for reliable tracking, and LED headlights and ditch lights (with beacons where applicable). Fully assembled and ready to run, it supports MU lashups via CV programming and includes a CV chart in the box; minimum radius is 18 inches with 22 inches recommended for best performance.
