Paperback. Condizione: New. Print on Demand. This book introduces the theory of maximum economy in grades and curves as a complete whole. It brings together in one volume the results of extensive experience and investigation on the part of the author and the practices of leading railroad companies. The author begins with an examination of the problem of balancing the forces that resist the movement of a train, and then derives the formula of maximum train movement and the formula for the most economical rate of grade. From this follows an investigation of the relation between grade and curvature, with a view to the production of the most economical line. The question of grade lines is treated at length, as is the establishment of vertical curves. The book concludes with a discussion of the calculation of earthwork and the methods of minimizing the cost of excavation.
