Heilmann locomotive

Okay, so imagine you have a toy train that needs to move on a really, really long track. But the train is heavy and needs lots of power to move. That's when people came up with the idea of putting a big engine at the front of the train to push it along.

Now, a Heilmann locomotive is a special type of engine that was developed a long time ago. It had a big boiler full of water and coal that heated up and created steam. This steam made the locomotive's pistons move back and forth, and that made the wheels turn.

But what makes the Heilmann locomotive special is that it had an electric generator that could make electricity from the steam power. And this electricity could be used to power the train's lights, heating, and even the brakes. So, the Heilmann locomotive was really smart and efficient, allowing the train to travel long distances without needing too many stops.

It might sound a bit complicated, but just remember that the Heilmann locomotive was a special type of train engine that was really good at making steam power and electricity to keep the train moving along smoothly.
