ELI5: Explain Like I'm 5

Handcar

Have you ever seen a big train that goes chugga chugga down the tracks? Well, sometimes people need to use their muscles instead of a big engine to move a train! A handcar is a special cart that people pump up and down with their hands to make it move on the train tracks. It's like going for a run, but instead of moving yourself, you're moving the handcar!

The handcar has a long handle on one end and a platform with wheels on the other end. People sit on the platform and push the handle up and down, which moves the wheels and makes the handcar go forward. It's kind of like pedaling a bicycle with your arms instead of your legs!

Handcars were used a long time ago when trains didn't have engines to pull them. People had to use their own strength to move the handcar and make the train go. They were used for things like delivering mail and supplies or helping workers get to where they needed to go.

Nowadays, you might see handcars used for fun on old train tracks that aren't used by real trains anymore. People can ride them for a fun and unique way to travel on the tracks. It's a little bit like going on a rollercoaster, but with your own muscles making the ride happen!
