Atlas N 40005598 EMD SD45 Low Nose Master Gold, Denver & Rio Grande Western #5325 (DCC and Sound)

This detailed Atlas N Scale Master Gold EMD SD45 with Low Nose is modeledafter diesels built by the Electro-Motive Division of General Motorsbetween 1965 and 1972 and operated by Class I and passed down to regionalsand shortlines. During the 1960s the demand for high HP locomotives droveEMD and competitor GE to continue to push the limits of locomotive design.During the time when 3,000 HP 16-cylinder prime movers were the norm, EMDmade the decision to introduce a 20-cylinder, 3600 HP design. Introduced in1965, the SD45, with its distinctive flared radiator design, was purchasedby many major US railroads, totaling over 1,200 units until the SD45-2replaced it in the EMD catalog in 1972. The SD45 did have some teethingproblems, most notably crankshaft failures. EMD did provide a means toremedy this issue, but some rail- roads chose to derate the SD45 to 3,000HP, or in some cases replace the prime mover with the 16-cylinder 3,000 HPas utilized in the SD40-2. Most railroads decided that the extra 600 HP waspushing the limits of the 645 prime mover and preferred the reliability ofthe 16-cylinder design. The SD40-2 proved to be the best choice for manyrailroads. It would take a new design, the 710 series prime mover firstfeatured in the SD50, for EMD to reach past 3,000 HP once again. Many unitsare still in service today, most being rebuilt as mentioned. Some didretain the stock 20-cylinder prime mover, a beefed-up engine blockmitigated crankshaft failures. Quite a few examples exist in museums,proving that despite some problems the EMD SD45 remains a popularlocomotive.
This Atlas model features details unique to each roadname and working frontand/or rear ditch lights if appropriate. Other features include afive-pole, skew-wound motor with dual flywheels, directional LED lighting,Accumate(R) magnetic knuckle couplers, accurate decoration androadname-appropriate body details. The Atlas N Scale EMD SD45 replica comeswith a low or high nose as appropriate for each roadname. This N Scalelocomotive replica comes equipped with a dual-mode Soundtraxx(R) Tsunami(R)sound and DCC decoder for operation on DCC and DC layouts (DC with reducedsound functions), and features a scale-speed motor with dual flywheels,directional LED lighting, accurate decoration and AccuMate(R) magneticknuckle couplers. This EMD SD45 is one of many Atlas N Scale locomotives.
