Built between November 1950 and December 1953 by General Motors Electro-Motive Division in the United States, with additional units constructed by General Motors Diesel (GMD) in Ontario, Canada, the SW9 was designed primarily for yard switching, industrial service, and light transfer work.\u003cbr\u003e\u003cbr\u003ePowered by an EMD 12-567B 12-cylinder two-stroke diesel engine producing 1,200 hp, the SW9 delivered dependable performance with robust low-speed tractive effort suited to frequent starts and stops typical of switching duty. Unlike its predecessor, the SW7, the SW9 lacked the upper hood vents and generally featured improved internal components, and late in production some units received a 567BC variant of the prime mover (with one final unit even equipped with a full 567C).\u003cbr\u003e\u003cbr\u003eDuring its relatively short production run, about 786 units were built for American railroads and 29 for Canadian operators, making it one of the more widely seen medium-power switchers of the era. The locomotive rode on B-B (four-axle) trucks and was adaptable enough that some railroads acquired paired \"cow-calf\" sets (TR5) where two units were semipermanently coupled for heavier switching tasks.\u003cbr\u003e\u003cbr\u003eRailroads appreciated the SW9 for its versatility, reliability, and ease of maintenance, traits that kept many in service for decades; numerous examples continued to work on short lines, industrial properties, and even on excursion or heritage assignments long after their Class I careers ended.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eGolden-white LEDs\u003cbr\u003eDirectional lighting\u003cbr\u003eSeparately-applied painted handrails (where appropriate)\u003cbr\u003eBlackened metal wheels\u003cbr\u003eScale Speed motor\u003cbr\u003eFactory-installed 1015 style magnetic knuckle couplers\u003cbr\u003eAccurate painting and printing\u003cbr\u003e\u003cbr\u003eDCC Operation Features GOLD LOCOMOTIVES ONLY)\u003cbr\u003eSupports all DCC-programming modes\u003cbr\u003eDCC includes RailCom and RailComPlus, with 14, 28 or 128 speed steps and with 2-digit and 4-digit addressing.\u003cbr\u003eFlexible mapping of function keys F0 to F28.\u003cbr\u003eA total of 6 DCC function outputs are available, and all can be function mapped (disable, brightness, light effects) individually\u003cbr\u003eFollows all NMRA DCC standards and recommended practices.\u003cbr\u003e\u003cbr\u003eESU LokSound Features (GOLD LOCOMOTIVES ONLY):\u003cbr\u003eOver 20 sound effects are available, including engine start-up and shutdown, prime mover sounds through all eight notches, bell, air horn, air compressor, dynamic brakes and more.\u003cbr\u003eThere are up to 16 user-selectable horns, 2 user-selectable bells, and 2 user-selectable synchronized brake squeals.\u003cbr\u003eManual and Automatic Notching modes with the ability to change modes \"on the fly\" are provided for true realism.","brand":"Atlas","offers":[{"title":"Default Title","offer_id":42323337281618,"sku":"ATL-40006396-PRE","price":24.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0581\/3410\/2098\/files\/n40006377_57e900dd-3553-476e-a176-fcc965f7c86c.jpg?v=1773773274","url":"https:\/\/modeltrainstuff.com\/products\/preorder-atlas-n-40006396-emd-sw9-psr-1816","provider":"Model Train Stuff","version":"1.0","type":"link"}
