Hop on board classic steam engines and see the United States as it once was: rugged, beautiful and, if you were a settler, more than a little bit daunting. From the Continental Divide and Donner Summit to the "Surfline," from Mt. Ranier to Mississippi and the Shenandoah, you'll see why the creation of the railway made travel less tragic than it used to be, and the natural beauty and spirit of adventure that helped a nation grow.
