How do trains run?
Trains run on rails, which are two parallel tracks of steel. The wheels of the train fit onto the rails and roll along them. The engine of the train pulls the rest of the train along the rails. The engine is usually a diesel engine, which burns diesel fuel to create power. The power from the engine is used to turn the wheels of the train, which then move the train forward.
Trains can also run on electricity. Electric trains have an electric motor instead of a diesel engine. The electric motor is powered by electricity from an overhead wire or a third rail. The electricity from the wire or rail is used to turn the wheels of the train, which then move the train forward.
Trains are a very efficient way to travel. They can carry a lot of people and freight, and they are relatively fuel-efficient. Trains are also a safe way to travel, and they are not as polluting as cars or airplanes.
