During the time when 3,000 HP 16-cylinder prime movers were the norm, EMD made the decision to introduce a 20-cylinder, 3600 HP design.\u003c\/p\u003e\n\u003cp\u003eIntroduced in 1965, the SD45, with its distinctive flared radiator design, was purchased by many major US railroads, totaling over 1,200 units until the SD45-2 replaced it in the EMD catalog in 1972. The SD45 did have some teething problems, most notably crankshaft failures. EMD did provide a means to remedy this issue, but some rail- roads chose to derate the SD45 to 3,000 HP, or in some cases replace the prime mover with the 16-cylinder 3,000 HP as utilized in the SD40-2. Most railroads decided that the extra 600 HP was pushing the limits of the 645 prime mover and preferred the reliability of the 16-cylinder design. The SD40-2 proved to be the best choice for many railroads. It would take a new design, the 710 series prime mover first featured in the SD50, for EMD to reach past 3,000 HP once again.\u003c\/p\u003e\n\u003cp\u003eMany units are still in service today, most being rebuilt as mentioned. Some did retain the stock 20-cylinder prime mover, a beefed-up engine block mitigated crankshaft failures. Quite a few examples exist in museums, proving that despite some problems the EMD SD45 remains a popular locomotive. The Atlas N Scale SD45 is an accurate rendition of the EMD design, matching many of the variations as seen during the production of the prototype locomotive.\u003c\/p\u003e\n\u003cp\u003eFEATURES:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAll new tooling\u003c\/li\u003e\n\u003cli\u003eGolden-white LEDs\u003c\/li\u003e\n\u003cli\u003ePainted safety rails\u003c\/li\u003e\n\u003cli\u003eDirectional lighting\u003c\/li\u003e\n\u003cli\u003eBlackened metal wheels\u003c\/li\u003e\n\u003cli\u003eMagnetic knuckle couplers\u003c\/li\u003e\n\u003cli\u003eAtlas Master® Series Gold Features:\n\u003cul\u003e\n\u003cli\u003eSoundtraxx Tsunami Decoder equipped\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eAtlas Master® Series Silver Features:\n\u003cul\u003e\n\u003cli\u003eNMRA 18-pin plug for DCC (Decoder-ready)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNOTE: Road number may vary from picture shown.\u003c\/p\u003e","brand":"Atlas","offers":[{"title":"Default Title","offer_id":51040489537749,"sku":"ATL40005598","price":229.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0520\/1972\/4454\/files\/atlas-40005598-n-scale-emd-sd45-diesel-rio-grande-d-rgw-5325-dcc-sound.jpg?v=1738365998","url":"https:\/\/www.whiterosehobbies.com\/products\/atlas-40005598-n-scale-emd-sd45-diesel-rio-grande-d-rgw-5325-dcc-sound","provider":"White Rose Hobbies","version":"1.0","type":"link"}
