Beginning in 1842 with a visionary's dream to span the continent with twin bands of iron, Empire Express captures three dramatic decades in which the United States effectively doubled in size, fought three wars, and began to discover a new national identity. From self-made entrepreneurs such as the Union Pacific's Thomas Durant and the Central Pacific's Collis Huntington, to era-defining figures such as President Lincoln, Generals Grant and Sherman, Mark Twain, and Walt Whitman, to the thousands of nameless laborers -- especially the Irish and Chines -- whose backbreaking work made the railroad possible, this extraordinary narrative summons an astonishing array of voices to give new dimension, not only to this monumental endeavor, but also to the culture, political struggles, and social conflicts of an unforgettable period in American history.
