Query: Trains Across the Continent: North American Railroad History

This is an excellent depiction of American railroading. The addition of some U.S. History makes this superbly interesting. Whether a railroad or history buff (or not), this reading will grab your attention. The light humor also adds to the enjoyment of this book. Filled with very interesting facts on how the early railroads actually created & perfected many of the technologies we know today. You won't want to put this book down once you start reading it!
