How Does a Train Driver Know When to Leave and Where to Stop? - Explained for 4-Year-Olds

A train driver is like a captain of a big, fast boat that runs on tracks instead of water. Here’s how they know what to do:

1. Signals: There are colorful lights called signals along the tracks. If the light is green, it means 'Go!' If it's red, it means 'Stop!' It’s like a traffic light for cars!
2. Train Schedule: The train driver has a special book or paper called a schedule. This tells them when the train should start moving and when it should stop at each station, just like when you have a playtime schedule!
3. Stations: The driver knows where the train needs to stop because of the stations. Each station has signs with names, just like your friends have names. When the train gets close, the driver gets ready to stop!
4. Communication: If the driver needs help or more information, they can talk to other train helpers through radios. It’s like using a walkie-talkie!

So, just like how you listen to your teacher or watch the lights when crossing the street, train drivers pay attention to signals and other helpers to know when to go and when to stop!
