Okay, little one! Let’s talk about trains! Imagine a big, long vehicle that travels on special tracks called rails. These trains have strong metal wheels that help them move. It’s like when you ride your toy car on a smooth surface!
Every train has a part called the engine. The engine is like the heart of the train; it helps pull everything along. Behind the engine, there are other parts called carriages. Think of carriages as the train's friends that bring passengers or things along for the ride.
So, trains are super cool! They use metal wheels to roll smoothly on the rails, and they have an engine and carriages that work together to go to many fun places!
