The most important means of transport in the 19th century was
Trains appeared in as early as the 16th century, when miners carried coal out of underground tunnels by putting wagons with wheels on rails. In the early 19th century the first steam train was invented and soon became the most important means of transport in the 19th century. Electric train was introduced towards the end of the 19th century. It soon replaced even the largest steam trains in Europe and America. The electric train has many advantages over steam power. In addition to its speed in running and ease in maintaining, it is quieter, cleaner, and does not produce pollution as a steam train does. It’s commonly chosen to run on subways. However, electric railroads with their rapid transit systems and commuter services can be expensive. Most developing countries cannot afford to replace all their steam trains with electric trains.
Today, trains are still an efficient means of transport throughout the world. For those who are not in a hurry, traveling by train is safer, and more economical than air transport. With more train lines added, and more carriages heated in winter and air-conditioned in summer, passenger trains are more comfortable than airplanes. More importantly, trains can help ease city traffic congestion and pollution. With the development of modern technology, there will be more demand for high-speed electric trains in most parts of the world.
