How did trains standardize time in the United States? - William Heuisler?

Before trains came along, people used to follow sun time, which meant each town had its own version of when noon was, kind of like how your clock at home might be a little different from the one on your phone.

When trains started moving across the country, they needed to know exactly what time it was in every city. If one train left Chicago at 12:00 and another left New York at the same time, but their clocks were off by an hour or two, they might crash, just like if you left your house thinking you had 30 minutes to get to school, but your friend left with only 15!

So, railroad companies decided to use a special kind of time called standard time, which divided the country into zones, like slices of pizza. Each zone had the same time, no matter where you were inside it. This helped trains run smoothly and on schedule.

Now, even though we don’t ride trains everywhere, we still use those time zones today, just like how your favorite bedtime story helps you know when to go to sleep!
