It was the first production AC traction freight locomotive in North America, with Burlington Northern receiving its first 9400 series units in late 1993. The key difference with AC traction motors is their higher durability compared to DC traction motors. AC motors do not burn out at low speeds from overheating, though they cost more than DC motors.\u003cbr\u003e\u003cbr\u003eFor some railroads in the 1990s, this was a clear advantage. BN had a booming volume of Powder River unit coal trains moving to powerplants, facing long, tough grades along the way. Colorado’s Joint Line is one, with a 40+ mile 1-1.5% continuous grade. BN was using sets of 5 DC SD40-2s and C30-7s as head end power to get up that grade, and the train had to stay above 10mph or more to prevent burnout on the DC traction motors. \u003cbr\u003e\u003cbr\u003eWith AC traction motors on SD70MACs, BN only needed three units on the head end, and they could grind away at any speed to conquer the grade. For BN, the cost advantage on this heavy haul traffic was huge, so the SD70MAC orders continued into the BNSF era. Ultimately, BNSF rostered 795 SD70MACs, far more than any other railroad. At present, much of the fleet is in storage, but the remaining active units are an interesting mixture of patched executive schemes and rebuilt SD70MACs.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Homeshops","offers":[{"title":"Default Title","offer_id":54778332315923,"sku":"RAP1058537","price":359.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/9283\/4323\/files\/RapidoSD70MACV_O_02bcb63e-2172-479a-8807-7e17edac5ee3.png?v=1790095218","url":"https:\/\/southeasthobbies.com\/products\/homeshops-rapido-1048537-ho-scale-sd70-mac-dcc-sound-virginian-ohio-v-o-4070-copy","provider":"SoutheastHobbies","version":"1.0","type":"link"}
