Sounds like you're having fun with your trains, and that's what it's all about, isn't it? Our previous house had a nice low shelf layout with two drop leaf style turns, dog-bone style. The previous owner took up all the O gauge track, but you could see where that 3-rail stuff was. I used it for my Flyer trains, and it served me well for years. Be sure to post some photos for us, OK?
I'm in the process of taking up my present layout in preparation for an eventual move, hopefully this coming Spring. It's sectional, so moving it is no big problem. But it's amazing how many trains I've accumulated over the years, though... I'll have a LOT of 1:64 vehicles and a few trains for sale at the upcoming Spring S Spree (shameless plug).
