Great photograph!!
I did very similarly. I put the trains away when I moved away for my first job. I built about a dozen 1/24 model cars during my single apartment days, and carried the tools and paints in a small box. I still have the cars, although several are in need of some parts glued back on. Fortunately I put each in the plastic show cases, so all the parts are still there. I may get to repairing them when I retire. When we got engaged I was 27, my wife to be got me an N scale train set, which I ran in our first house.
