A simple explanation for children about how trains operate, their components, and their purposes.
A train is a big vehicle that moves on tracks made of metal called rails. It has strong wheels made of metal that help it roll smoothly along these tracks. The front part of the train is called a locomotive, and it pulls long connected sections called carriages.
Some trains are designed to carry people. These are called passenger trains, and they take people from one place to another. Other trains carry goods, like food or toys, and these are called freight trains. So, trains are very helpful because they can transport both people and things!
