Okay kiddo, have you ever seen a machine with gears before? Gears are like little wheels with teeth on them that fit together with other gears to make things move.
Now, a drawgear is a special kind of gear on a train that helps connect the train cars together. Think of it like a really strong magnet that holds everything in place.
When the train is moving, the drawgear allows the cars to move together smoothly without coming apart. It's like how your toy cars stay connected when you push them around on the floor.
But drawgears have to be really strong because trains are really heavy and can move really fast. So they are made out of really tough materials like steel and iron.
So basically, a drawgear is a special kind of gear on a train that helps connect the train cars together so they can all move as one big machine. Pretty cool, huh?
