8 1/2 x 11 - Hardbound, 300 pages, 320 illustrations, color plates, rosters, bibliography, and index. The Northern Pacific Railway entered the diesel era with a large fleet of modern steam locomotives, but gradually and then more rapidly, made the transition to diesel-electric motive power. Covering in detail, all of the road's diesels - the first generation switchers, the early road units, and the postwar road- switchers. The more powerful and technologically advanced second-generation units such as U25C, the U28C, the SD-45, and the U33C units are presented."
