When people think of traveling, it is usually in terms of the ultimate destination and less often about the journey itself. You may point out cruises as an exception — but cruises are different in the sense that companies have created ships so packed with activities, attractions, and specialty dining that even cruise ships have become destinations themselves.
Trains, however, are much different. They strip away all the extra distractions and focus on only a few things — dining, sleeping, and luxury comfort — leaving the natural beauty of the passing surroundings to do the heavy lifting in terms of visual entertainment. Some journeys can last as long as two weeks with stops in various cities, such as the Golden Eagle Danube Express’ Treasures of Eastern Europe tour, or as short as an hour and a half, such as the Western Highland, which takes you to Mallaig (or possibly Hogwarts) from Glasgow by way of the Glenfinnan Viaduct on Scotland’s west coast.
