In the United States, train transportation is unpopular compared with cars and airplanes. Most people like traveling by car or by air. Officials of the United States Department of Transportation made a study in 2001. The study is about how many miles Americans traveled by different means of transportation. They only studied trips longer than 50 miles. The study showed that fifty-six percent of all miles were traveled in personal vehicle. Forty-one percent were traveled in an airplane. Two percent were traveled in a bus. And less than one percent of miles were traveled in a train. Amtrak is the national provider of train transportation in the United States.
