Reply to "Is Your Train Purchasing Rational?"

For me, I wouldn’t Exactly call spending the amount of money that I have on this hobby  “rational”, but I do have a system. I limit my purchases to certain lines (lirr, Military,  mta, etc) and the curve limitations of my existing layout. I rarely purchase duplicates, even if the newer model has an upgraded command system and the era for everything must be earlier than the 1990s (no modern).  My other rule is that everything must either fit on the layout (mainline or side track) or on my shelves- nothing is purchased and kept in a box. Needless to say, I’ve added considerable shelving over the years, LOL!
