Flashback from the 90s.

I remember when I was a toddler there was a mall in a city an hour from where I live that had display cases with trains. The display cases were big enough to house a small model train layout and there were usually 2 or 3 trains in them. You put a coin in and push a button and make them go for a couple of minutes. That mall was torn down over 20 years ago. Those were the days.
