Empire Express: Building the First Transcontinental Railroad is a book written by David Haward Bain, published in 2000. It follows the initial conception of the idea of a transcontinental railroad, during the two decades before the Civil War, to the work of the engineers and entrepreneurs who fixed the route, assembled financing, drafted a work force and launched the two lines toward the eventual meeting point at Promontory Summit, Utah, in 1869. The story alternates between the Union Pacific driving west from Omaha and the Central Pacific blasting through the mountains from California.
