In the United States, train transportation is unpopular pared 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. In the past ten years, the number of its passengers has increased by eighteen percent. Although the number of passengers has increased, it is still very small now. In countries such as France, Germany, or Japan, more people use trains.
There are several reasons why many people .
Firstly, Americans love to drive their own cars. On highways, cars can travel as fast as trains. These highways connect all major cities in America．Secondly, many travelers like to be independent. When they use their own cars they can decide when to travel. Thirdly, many buses travel between major cities. Bus travel is less costly than train travel.
In a huge country like the United States, cities are far away from each other. In some cases, travel from one city to another by train may take more than a day. Airplanes can carry passengers over long distances much faster. People who do not want to spend long time traveling by train decide to fly. For these people saving time is the most important thing.
