Prototype History: Notable as the first locomotive with an engine larger than 16 cylinders upon its introduction in 1965, the EMD SD45 was used on nearly every railroad at one time or another. Over the course of six years, EMD built a whopping 1260 SD45 locomotives for freight use on more than 25 railroads, with many more acquiring them second-hand. The SD45, while sharing the same common frame as the EMD SD40, was distinguished by a number of characteristics such as the flared radiator that stretched across the side of the locomotive's long hood. Several SD45 locomotives are still preserved and in service today.
