The EMD SD45 stands as one of the most powerful and distinctive 20-cylinder diesel locomotives ever produced. Built on proven frames with other EMD staples like the SD40 and SD38, EMD manufactured 1,260 SD45 locomotives between 1965 and 1971. These impressive freight haulers featured EMD's revolutionary 645E3 20-cylinder prime mover delivering a remarkable 3,600 horsepower, making them standout performers on major railroads including Burlington Northern, Southern Pacific, Santa Fe, Pennsylvania, Great Northern, UP, NP, and many others. Broadway Limited's HO scale SD45 models capture the prototype's legendary power and distinctive appearance with museum-quality detail.
