What's a Train?
Trains are big vehicles that travel on tracks. They carry people and things from one place to another.
Special Routes for Trains
Trains can only go where the tracks are. These tracks are set up in a special way, called routes. Just like a game path, trains follow these tracks to reach their destination.
What Are Traffic Lights?
Traffic lights are signals that tell cars, buses, and even trains when to stop and go. This way, everything can move safely without crashing into each other.
What is a Semaphore?
A semaphore is a kind of traffic light that looks different from the ones you see on the road. It uses colorful flags or lights to show trains if they should stop or go. When the light is green, it means the train can move forward, and when it’s red, the train must stop. Semaphores help keep trains safe on their special routes!
