How Trains and Traffic Lights Work

Okay little one, let’s talk about trains and traffic lights!

Trains

Trains are big and fast, like a giant toy that goes choo-choo! They have special paths called tracks, just like your toy cars have special roads to drive on. The trains always follow these tracks so they know where to go.

Traffic Lights

Now, let’s learn about traffic lights. These lights help cars stop and go. When the light is green, it's like saying 'Go!' and the cars can move. When it's red, it means 'Stop!' so cars don't bump into each other. It helps keep everyone safe.

Semaphore

There’s something special called semaphore for trains! It's like a traffic light for trains. It uses colors and signals to tell trains when to go or stay still.

So, trains follow their tracks and traffic lights help cars. Everything works together to keep us safe, just like how you have to stay on the sidewalk when you're walking!
