My father was one of the biggest model railroad enthusiasts that I had ever heard of. He used to love to get "caught" at railroad crossings so he could watch the trains go by. And the more the better. He was a civil/structural engineer by trade. We lived in NW Philadelphia suburbs and he worked in downtown. Mom would drive him to the train station in the morning so he could take the Reading down to work. Me, being the innocent little tike that I was, thought he was a train engineer!
Here is a picture of part of the first train set that he ever received. It's part of a Lionel set that he got from Santa one year. My brothers and sister have just as many! I just put them up on a peg rail in the living room. I think I need to make some stitcheries to hang on the wall behind them.
