I had two buddies in St. Louis that had trains in the 1950s, me Marx, one Lionel and other American Flyer. Our layout were on the living room floor for about 2 weeks during the Christmas holidays. My family moved to the county and I lost touch as we moved three more times through high school. My brother and I lost interest in trains about age 8 and 10 and moved on to model building, U control planes and boats with radio control that had tubes!
I got interest in trains 1970 s when married, with two children, and built a portable layout, in Jamaica, that moved 7 times and to 6 states. This is the same layout I have now and have written about in long topic on OGR.
Several years ago I located one of my buddies from the 1950s and contacted him, he replied and followed up but he dropped the communication. We never got to writing about trains but I found out he was an engineer with McDonald Douglas in St. Louis where his father had been a machinist when were were kids. My father had been an engineer for 43 years with Alcoa and I was an engineer for Alcoa for 20 years. We both sort of followed our fathers.
