America has a long standing love affair with trains. From its yesteryears of transporting ore through the Wild West to present-day journeys, the railroads were a crucial part of the creation of the National Park System, taking early visitors to Yosemite, Yellowstone, Glacier, and other parks that were nearly inaccessible by other means. Although roads have made access easier in recent history. Today National Parks, National Historic Sites, National Historic Landmarks & Historic Civil Engineering Landmarks preserve America's rich rail history and delight millions of people from around the world through scenic rail excursions and informative interactive exhibits.
