Okay, little buddy! Let’s talk about trains and traffic lights!
First, trains are like big, fast friends that move on special paths called tracks. These tracks are just like roads for cars, but they are made of metal and let the train glide along smoothly.
Now, trains need to know where to go, just like cars do. That’s where traffic lights come in, but not the same kind you see on the road. Trains have special lights called semaphore lights!
Semaphore lights help trains know when it’s safe to go. When the light is green, the train can move fast! But when the light is red, the train has to stop and wait until the light turns green again. Just like how we stop at red lights when we are in a car!
So, trains use their tracks to travel and special semaphore lights to know when to go or stop. Isn’t that cool?
