"The essential photographic reference to modern North American locomotives." This remarkable large-format reference is a revised, updated and expanded work based on the author's "Field Guide to Modern Diesel Locomotives." Locomotives covers all mainline models built for North American railroads from the mid-1 970s to today, from EMD Dash 2s and GE Dash 7s to the latest 70 Series and Evolution Series models, as well as Green Goats, Gensets and mainline passenger electric-powered locomotives. Containing nearly 300 photographs of the more than 120 featured locomotive models from every locomotive manufacturer, this is the definitive reference for the North American rail fan. Greg McDonnell provides concise yet comprehensive information on each model, along with easy-to-read tables of production totals, build dates and mechanical specifications.
