I am brand-new to the world of model trains after a 35-year hiatus. My house is small and I am trying to design a shelf layout in my "man cave". The room is small (about 10' x 9'), is more or less square but it has multiple 45 degree angles yielding a total of ten faces ranging from 17" to 116" in length.

I picked up a good sized lot of EZ track on eBay which consists of 18" radius (I think) curves and 9" straight sections.

I am having trouble figuring out how to lay this out to maximize my layout size while, at the same time, keeping the track as close to the wall as possible.

Does anyone have experience with this that can help me to engineer this? I am thinking that I will need curves of multiple radii but I do not even know what radii are available.

Thanks in advance!
