A word used to describe someone that films trains. It is not a job, it’s a hobby that anyone can do. It doesn’t matter what, at what time, when, and where you railfan, as long as you enjoy it. Anyone can become a railfan if they want. It doesn’t matter what device you use to film trains
John is a railfan that always goes to a train station near him.
