13Mtrainer, If you look at the attached pic, you will see that the lay out is 14.5'x6.5'. You will also notice that there are only very short straight sections between all the various curves. Couple this with the fact that all of the radii except one are 18" and I would have to say that this particular layout couldn't be "shrunk down" more than a half ft. or so. However, that doesn't mean that you can't incorporate many of the elements that you like best into a smaller space. Why not post a graph paper style pic of the available space you have, along with what you would like to have on the layout, and let the people here help. They all have helped me!.......Miles, thank you for the encouragement. Galen, I'm planning on a deck girder with piers. I'll post more pics when I can....
