1 . With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it’s comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible.

Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.     1     But no matter when you travel, it’s a good idea to make your reservations at least 90 days in advance.

Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.     2     Then you won’t have to walk through several cars on a moving train three times a day for your meals.

Bring a blanket. When you’re riding on trains, you won’t be provided with a blanket for free, even if your trip is an overnight one.     3     In the summer in particular, the air conditioning can make them quite cold.

Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.     4     Note: The times listed on the schedules are departure times, not arrival times.

Have fun.     5     Read a book, knit, do a crossword puzzle, or simply watch the world unfold outside the window. To calculate your speed as you do, divide 3,600(the number of seconds in an hour)by the number of seconds it takes you to travel one mile(the distance between two mileposts). If it takes the train 53 seconds to travel one mile, you’re going 67.92 mph.
