John, Even with months of planning, RRTrack designs and input from many, it still evolved once I began building, using fastrack left me without many options for on the fly custom bends, but it all began to take shape when I laid it down, and wound up with a reversing elevated section which added that function and gave me a lot better layout for multiple operations.
I just wish I had more real estate for a larger yard than I got, fortunately, switching is not a huge part of my fun.
I really like the way you optimized and kept the 072, I just couldn't get that much space and wound up with 060 and 048 main lines.
