Padarn railway is like a little train that runs on a track around a lake called Llyn Padarn. It's a special train because it's powered by electricity instead of coal or gas like old trains were.
The train might look small, but it's actually really strong! It can carry lots of people at once, even though it looks like it might be only for kids.
People like riding on the Padarn railway because they can see lots of interesting things along the way, like pretty trees and flowers, the glittering lake, and even an old slate quarry.
It's like going on a special adventure, where you get to ride through beautiful scenery and learn about the history of the place you're visiting. So if you get the chance to ride the Padarn railway, give it a go!
