I purchased a license for SCARM and was learning to use it. I decided that I had a lot of old 0-27 track and swtiches but not much space. So I set the goal of trying to have an interesting layout in a 36 X 72 inch space. Well I over shot the space by a bit and ended up around 44 X 78 inches. My first version was a flat layout shown here.
So I then moved on to learning elevations so I added a reversing loop on trestles. Kept going and added a sub-level with another reversing loop to make for a very long outer main line and a shorter inner loop.
In the above picture the main level is in blue, the upper reversing loop is in green, an the sub-level reversing loop in in red.
Not sure I'm going to build this yet, but definitely has me intrigued as to how much I could fit into a small space. Be warned if you decide to build this I'm not sure I have proper clearances throughout so you may want to mock it up first.
