So im making a lay out on my living room floor because I am cheap like that.....how ever what is a turn radius that is more real world on a main line I mean o72 obviously would only work in a rail yard but 108 seems huge!!! I mean 9ft to turn around.......I want to be realistic but my living room is not that big.....so I was wondering if o81,90,99 would give me a realistic look so I can save space and not look so awkward on the corners thanks
