Greg, Thank you for mentioning my 4'x7' layout that was published elsewhere. The only restriction with that publisher is that I can't show any of the photographs that were in their article.
Holly, The layout was actually developed on a discussion here on the OGR Forum, so we can go over all of that again. Many folks contributed ideas. I started discussion a couple pages before on the long standing topic What Did You Do On Your Layout Today This link is at the bottom of Page 610 dated 11/7/18, and I posted my progress there for several days until the layout was done. Here are some samples.
One thing I will point out is that I made all the supports out of left over plastic porch railing stock. Here is how I did that.
