As the subtitle states, "The illustrated history of North America's favorite locomotives." Longtime railroad enthusiast and author Solomon surveys the history of the classic streamlined diesel-electric locomotives that revolutionized both the nature of railroading (from steam to diesel) and the nature of locomotive building (from unique designs developed by and for each individual railroad, to standard designs adaptable to any railroad). The book ranges from the birth of the Electro-Motive Company to development of the "567" class diesel engine, through the various models of E and F units in their heyday, to the continued use today of Es and Fs on various railroads' flagship executive fleets. Wonderful vintage color and black-and-white photos, along with modern photos of surviving Es and Fs still in operation, illustrate the text. As is often the case with general history texts, I sometimes found myself wanting more detail: More nuts and bolts, so to speak, about the various iterations of generator sets or traction motors or various truck designs, or more operational details from the perspectives of train crews or railroad executives. But all of those subjects are at least touched on, and I recognize the limits of time and pages--no one book could contain all the details various readers might want. For fans of EMD's first-generation diesel locomotives, this book is a keeper.
