"The first part of the book (1856-1916) examines the railway's early strategies and philosophy, relations with employees, and vigorous campaigns to develop the service area. The second part (1916-1970) offers an assessment of a dramatic period of transition for the railroad - international conflicts, the Great Depression, the rise of motor vehicles, increasing labor costs, and stronger unions." "Illustrated with more than two hundred maps, period photographs, and drawings, the volume also includes appendixes listing the original tracklaying history, track removals, ruling grades on main freight routes, and main line ruling grades from Minneapolis to Seattle."--BOOK JACKET.
