London Underground
The world’s first subway was built in London in 1863. At the time，the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work， they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems，the idea of the London Underground，the first subway system，was born.
The plans for building the Underground met with several problems and delays，but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30，000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed)， and pleasant decorations inside each of the cars. However， the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰)， as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems，riding in the Underground did catch on. It carried 9 million riders in its first year.
