Railfan

Well, a railfan is a person who really loves trains! They think trains are super cool and interesting, and they like to watch them and learn about them. Just like some kids really like cars or airplanes, some grown-ups really like trains!

They might go to train stations and watch the trains come and go, or they might even ride trains just for fun. They might also collect things related to trains, like pictures or models.

Railfans also like to learn about the history of trains and how they work. They might know a lot about different kinds of trains, like steam engines or high-speed trains. They might even be able to tell you lots of interesting facts about trains, like how they were invented or how they help move things around the country.

Overall, being a railfan is just like having a hobby, but it's all about trains!
