Train travel in the United States may not be as common or practical as in other parts of the world, but that does not mean it’s nonexistent — far from it. There are high-speed trains operating on the coast of Florida; there are Amtrak trains that will take you through some of the nation’s most beautiful national parks; there is a train in Colorado that runs at the bottom of a 1,200-foot-deep gorge and one that goes through California’s most celebrated wine region; and there are trains in Alaska that will take you for the ride of a lifetime through the most spectacular scenery — in glass-ceiling cars, no less!
