Trains are very efficient. The tracks spread the weight of the train. This lets trains carry more than trucks on roads. The wheels also slide easily on rails. This means there is less friction, or rubbing, than with rubber tires. Because of this, we can link many cars into one long train.

Long ago, people used humans or animals to move carts.
