Welcome... I am a very visual person and I found that I could draw out the track plan a hundred times and not get a real good feel for it. I made mock up scale buildings out of dollar store foam core, played with layout and track. i used drywall tape and switch templates pulled off the internet to "see" how my plan actually worked and it only cost me like $4 This is the saw mill complex that I am building as a module. I agree with Ken, come up with a working track plan and build some mock ups.... O scale is huge but so worthwhile. my shop is 25X30 and I am thinking about an expansion. good luck keep us posted
