It models the six-axle diesel-electric with a 16‑cylinder EMD 645E3 engine delivering 3,000 horsepower, produced between 1974 and 1980, and mirrors the cooling-system modifications that earned the nickname tunnel motor, including rear radiator intakes and see-through grilles. The model includes onboard Econami sound by SoundTraxx and supports both DC and DCC operation, delivering realistic engine, horn, and bell sounds when driven digitally while remaining operable on traditional DC layouts.\u003c\/p\u003e\n\t\u003cp\u003eBuilt for realism and reliability, it features fine-scale handrails, see-through cab windows, see-through radiator grilles, LED lighting, and a detailed injection-molded body. The drivetrain uses all-wheel electrical pickup, a 5-pole motor with flywheels, and a multi-link gear train for smooth, quiet operation on standard HO track, with a recommended minimum radius of 22 inches. A DCC-ready 21-pin NEM Quick Plug connection and RP25-contour wheels ensure compatibility with common HO layouts, while the livery faithful to D\u0026amp;RGW 5344 adds an authentic finishing touch for serious modelers.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn (ATH)","offers":[{"title":"Default Title","offer_id":47906416164916,"sku":"ATH72171","price":239.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATH72171.jpg?v=1781653795","url":"https:\/\/nankinhobby.com\/products\/ath72171","provider":"Nankin Hobby","version":"1.0","type":"link"}
