AS a train lover, I like to watch youtube videos with trains around the world and so i can say that USAhas some very interesting rail journeys. Recentily I saw a video of trip from Anchorage to Fairbanks in Alaska, i loved the scenarios and sure would love be able to make a travel like that.
the only problem is the price, because both in the USA and europe, mostily is cheaper go by plane than by rail...
