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
A large table that is home to scale model trains as part of the hobby of model railroading. Commonly known as a layout. Model Railroads can vary in realism from fictional (freelanced) to prototypical, and size from a simple 4x8 plywood sheet to a "basement empire". Often confused for simply running toy trains in a circle, or oval. (which it can include)
Bob: Hey Dave, you got any hobbies?
