内容説明 A revision of the classic text on railroad engineering， considered the ``bible’’ of the field for three decades. Presents railroad engineering principles quantitatively but without excessive resort to mathematics， and applies these principles to day-by-day design， construction， operation， and maintenance. Relates practice to principles in an orderly， sequential pattern (subgrade， ballast， ties， rails). Applicable to both conventional railroads and rapid transit systems.
