This makes me again want to do things with the stupid amount of N scale stuff I bought while working at The Great Train Store briefly before the chain went out of business. We started to put something together in my parent's basement, but it was never finished because I designed it to make good use of turnouts. It's a 10'x10'x L-shaped, double-deck monstrosity that calls for hundreds of #6 turnouts. I couldn't afford them all.
My dad had model trains as a kid and I love miniatures, so I love them as well. My brother has Lionel trains of his own, even, in addition to my father's HO stuff.
