A subway is like a train that runs underground and takes people from one place to another quickly.
Imagine you're playing with toy trains in your room, instead of moving along the floor, these big trains zoom through tunnels beneath the city, just like how your toy train might go under a table or couch.
Subways are special because they help lots of people travel at the same time, even when it’s busy outside. They have cars, which are like the compartments in your toy train, except these ones hold many people and can be as long as several cars lined up together!
How a Subway Works
When you want to ride a subway, you go into a station, kind of like how you enter a playroom. You find the right track (or path) for where you're going, then the train comes in and takes you through the city like it's playing a game of hide-and-seek with the streets above.
Sometimes people say subways are "like moving sidewalks that go really fast", because they carry you underground without needing to walk.
