Multiple Unit

Have you ever seen a train with many cars, like a subway train or a city tram? Sometimes, those are called multiple units! That means that all the cars are connected to each other and are controlled by the same driver. Imagine a toy train with many cars, but instead of pushing it with your hand, there's a person inside a special driver's cabin who is in charge of making all the cars go. This way, the train can move smoothly and take lots of passengers from one place to another. Multiple units are great for transportation because they are efficient and can carry many people at once!
