This is a new layout I am looking at building in a spare basement room. The dead end track in the lower right goes to a living room loop. 
The idea here is that I can run up to 3 trains with no user input or 1 train that covers all the main lines. Basically an upper loop, lower loop, living room loop or combine this all. 
As of right now I am in the brainstorming stage. Only focusing on the main lines. Still need to decide where to put tunnels and bridges.

I am happy with the layout. I could go wider with the tables but I think the physical reach will become too large. I plan to use all flex track for the layout but find found it easier to use this tool with the short sections for the most part. The layout will be mostly mountains tree covered. I will only have a few structures on the layout. It is designed for running long trains.
