The new locomotive was to use EMD’s newly-developed 265H prime mover, featuring 6000 horsepower. However, this engine was experiencing technical problems in development, which led to the first groups of locomotives being delivered with the EMD 710G prime mover of 4300 horsepower (the intent being to retrofit these with the more-powerful 265H at a later date). Ironically, the technical problems with the 265H were never fully resolved, and no conversions were done. The 710G-engined SD90MACs outlasted their later 265H cousins in service by a wide margin, with some units only recently having been retired or sold by Union Pacific, and other railroads choosing to rebuild them for continued service.\u003c\/p\u003e\n\u003cp\u003eThe Athearn Genesis SD90MAC features all of the cutting-edge detail and operational features that are expected by discerning modelers: Working number boards and ground lights, see-through steps, numerous separately-applied details on the body and underframe, and a heavy die-cast frame for massive pulling power.\u003c\/p\u003e\n\u003cp\u003eDuring the horsepower race of the 1990’s, EMD offered an “upgradable” SD90MAC. EMD’s 6000hp 256H prime mover was still being tested for reliability and issues at the time and UP needed power quickly. To combat this, EMD offered the SD90 with the 4300hp 710 prime mover in it’s place until the 256H prime mover was ready to be installed after successful testing. Unfortunately, the 256H was deemed too problematic and the conversion was never completed. UP classed these as SD9043MAC’s. Purchased in 1996, these big brutes were initially used in coal drag service before ultimately being used in other types of service. They were factory delivered with the “We Will Deliver” slogan. By the mid 2010’s, a large batch were sold to NS for rebuilding into SD70ACU’s.\u003c\/p\u003e\n\u003cp\u003eFEATURES:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLeslie 3-chime horn\u003c\/li\u003e\n\u003cli\u003eFront ditch lights\u003c\/li\u003e\n\u003cli\u003eLarge EMD plow\u003c\/li\u003e\n\u003cli\u003eIlluminated ground lights\u003c\/li\u003e\n\u003cli\u003eIlluminated number boards\u003c\/li\u003e\n\u003cli\u003eEtched, see-through walkway steps\u003c\/li\u003e\n\u003cli\u003eDual Sugarcube speakers for optimal sound quality\u003c\/li\u003e\n\u003cli\u003eMinimum radius: 18” — Recommended radius: 22”\u003c\/li\u003e\n\u003cli\u003eAnimated Roller Bearing Trucks\u003c\/li\u003e\n\u003cli\u003eCoupler cut levers\u003c\/li\u003e\n\u003cli\u003eTrainline hose\u003c\/li\u003e\n\u003cli\u003eFull cab interior\u003c\/li\u003e\n\u003cli\u003eWindshield wipers\u003c\/li\u003e\n\u003cli\u003eWire grab irons\u003c\/li\u003e\n\u003cli\u003eRubber MU hoses\u003c\/li\u003e\n\u003cli\u003eSee through cab windows\u003c\/li\u003e\n\u003cli\u003eWalkway tread\u003c\/li\u003e\n\u003cli\u003eLift rings\u003c\/li\u003e\n\u003cli\u003eSander lines\u003c\/li\u003e\n\u003cli\u003eDCC-ready features Quick Plug\u003csup\u003eTM\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eplug-and-play technology with 21-pin NEM connector\u003c\/li\u003e\n\u003cli\u003eFine-scale Celcon handrails for scale appearance\u003c\/li\u003e\n\u003cli\u003eDetailed fuel tank with fuel fillers, fuel gauges, and breather pipes\u003c\/li\u003e\n\u003cli\u003eBody-mounted McHenry® operating scale knuckle couplers\u003c\/li\u003e\n\u003cli\u003eGenesis driveline with 5-pole skew wound motor, precision machined flywheels, and multi-link drivetrain for trouble free operation\u003c\/li\u003e\n\u003cli\u003eEight-wheel drive with precision gears for smooth and quiet operation\u003c\/li\u003e\n\u003cli\u003eAll-wheel electrical pickup provides reliable current flow\u003c\/li\u003e\n\u003cli\u003eWheels with RP25 contours operate on all popular brands of track\u003c\/li\u003e\n\u003cli\u003eLED Lighting for trouble free operation\u003c\/li\u003e\n\u003cli\u003eHeavy die-cast frame for greater traction and more pulling power\u003c\/li\u003e\n\u003cli\u003eScaled from prototype resources including drawings, field measurements, photographs, and more\u003c\/li\u003e\n\u003cli\u003eAccurately painted and printed paint schemes\u003c\/li\u003e\n\u003cli\u003eFully assembled and ready-to-run\u003c\/li\u003e\n\u003cli\u003ePackaging securely holds the model for safe storage\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Athearn Genesis","offers":[{"title":"Default Title","offer_id":43529638281429,"sku":"ATHG27278","price":220.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0520\/1972\/4454\/products\/athearn-genesis-g27278-ho-scale-emd-sd90mac-union-pacific-up-8037.png?v=1661705309","url":"https:\/\/www.whiterosehobbies.com\/products\/athearn-genesis-g27278-ho-scale-emd-sd90mac-union-pacific-up-8037","provider":"White Rose Hobbies","version":"1.0","type":"link"}
