I was watching an old episode of "King of Queens" that has as it's subject a husband who spends all his time playing with trains and going to train shows. There are a few good shots of a train layout at home and at a train show. It is also a cautionary tail about not getting too involved with your train hobby. Some of us might feel that we can identify a little too closely with the train addict. There is a real layout disaster at the train show towards the end that is very funny.
