This invaluable volume spans more than 150 years of locomotive technology to examine the wide variety of steam, diesel, and electric locomotives that have powered ninety North American railroads, past and present, through the decades. Since locomotive-building has long been a made-to-order business, the book is arranged alphabetically by railroad to give you a better understanding of how specific technologies suited specific needs.

The railroads featured range from the best-known historic lines, such as the Canadian Pacific, Santa Fe, Union Pacific, and Baltimore & Ohio, to today's giant Class I roads, commuter lines, and selected short lines. The result is a beautifully presented reference guide that features more than 400 locomotive gems, including historic machines such as New York Central's J3a Hudsons, Pennsylvania Railroad's GG1 electrics, and EMD's classic E- and F-Units, to today's most powerful modern diesels.

All the major builders - past and present - are represented, including such heavyweights as Baldwin, Alco, Lima, EMD, GE, and more.
