A. In the 19th century, railroad travel became the fastest way to travel long distances overland. It was a great improvement over travelling by horse and wagon, which could take weeks longer than the train. But early trains weren't comfortable. Seats were hard and the soot from the coal engine made the air very dirty. In addition, the cars were cold in winter and hot in summer because there was no heat or air conditioning. But fortunately, since those early years, train travel has become much more pleasant.
B. Some long-distance passenger trains have become famous. For example, the Trans- Siberian Railway in Russia is the longest railway in the world, covering 9,259 kilometers and 10 time zones. In the United States, the California Zephyr travels between Chicago and San Francisco, and during the 3-day trip, passengers can enjoy amazing views of the Rocky Mountains. The Orient Express between Venice and Istanbul offers old-fashioned service that is luxurious, romantic, and expensive.
C. In many countries, overnight trains are a good option to air travel. For example, you might leave one city at 11:00 at night, and arrive at your destination at 7:00 the next morning. Typically, you share a cabin with three other people, who you might be travelling with, or who you might not know at all. Your seats become your beds and the price of your ticket includes your bedding. If you want, you can order tea and a snack from the cabin attendant.
D. Of course, not all trains carry passengers. Many trains are freight trains, transporting goods from one location to another. The busiest freight system in the world is in China. Freight trains are usually much longer than passenger trains. The longest freight train recorded was in Australia with over 682 cars. Freight trains can carry anything — coal, cars, clothing — anything that people need. Refrigeration, which keeps food cold and fresh, revolutionized freight transportation.

Many countries around the world are investing in high-speed trains. Today's high-speed railways are amazing. They can go twice as fast as regular trains, and they are designed for passenger comfort with spacious chairs, internet access, and multi-media entertainment. High speed rail makes it possible to move many more people much faster over longer distances. High speed rail also can help the environment because it is more energy efficient and reduces cars on the roads.

E. The invention of the steam locomotive made a breakthrough in the development of the railway system in the 19th century. Today the technology seems ordinary, but two hundred years ago it was revolutionary. Steam locomotives were fueled by burning coal, wood or oil, to produce steam in a boiler, which drove the engine. Of course, large amounts of water were also needed. In the 20th century, steam engines were gradually replaced with trains fueled by diesel or electricity.
F. Authors have been using trains in literature for as long as trains have been running. Indeed, it's hard to imagine some stories without a train in them. Even people who have never read Anna Karenina know how the famous novel's heroine dies at the end. Many American children learn the important lessons of optimism and hard-work reading the classic story The Little Engine that Could. And of course almost everyone on the planet knows about Hogwarts Express in the Harry Potter books.
