Transportation historian Christian Wolmar celebrates the vision and determination of the ambitious pioneers who developed the railroads that would one day span continents, as well as the efforts of the laborers who overcame horrific conditions to enable this global network to emerge. In this book, Wolmar shows how cultures were enriched, and destroyed, by the unrelenting construction of these railroad networks and how they quickly took on a vital role in the U.S. Civil War as well as in two world wars.
