This carefully researched and well written book by an eminent western railroad historian describes the conception and building of the Western Pacific, a railroad that was a pacific extension for the Denver and Rio Grande. Coverage includes the northern California extension, built to connect with the Great Northern 1931 entrance into the Golden State, as well as a summary of later WP operation right up to the 1982 merger into Union Pacific and subsequent developments. 232 pages, 27 maps, 17 color and over 200 black-and-white illustrations, detailed index. This is in very good condition.
