Reply to "Can I fit 2 072 3 rail loops in this space?"

Working on my bench work no track plan yet. I'd like to fit 2 o72 loops I have a 45 inch double track truss bridge with 8.5 inches of track width space so I may have to change the curves at the bridge end or widen the middle isle. 11x20 

Ok, remember when I said that doing the benchwork and then making the layout makes it harder? Well, I've been trying to do a track plan for you that is something other than a symmetrical oval. When you throw in a 45" bridge attaching to a three foot wide benchwork, AND want 072 curves, there just isn't enough room. The 072 is diameter is measured from the center rail. A circle of 072 is MORE that 72" outer edge-to-edge.

So, here's my question. Is your isle centered to a door entering the room?
