     We all know that as the population of a city grows, so do its problems.

Pollution,  too  many cars, and crowded streets are just a  few of these

difficulties.  One way to help with these problems is city trains. Trains

traveling to different parts of a city means fewer cars and buses on our roads, cleaner air, and more open streets. In recent years, cities such as Guangzhou, Shenzhen and Shanghai have all built city train lines.

     The first city train line in China was built in Beijing. The oldest part of the train line, from Beijing Stop to Pingguoyuan, was opened in 1969.  Its length was 23.6 kilometres. As the city grew after 1980, so did the need for more

trains.A newer train line was built to help move people around the city centre. The 16-kilometre-long "circle line" was finished in 1987. Since that time

even more train stations have been built and today the train lines in the city

are over 50 kilometres long.

    For  the  coming beautiful  future,  the trains of Beijing will be very

important.  We all know that most of the people who go to work or go to

school will travel by train.
