Before you commit to a plan, ask yourself how you plan to operate. If you just want a plan to make up a few trains in a yard and run them around a loop (a folded dogbone is just a loop in disguise with an up-and-over), then this plan may be perfect for you after modification to fit your room space.
But, if you really want to "operate," then this plan needs modifications. As far as I can tell, there is only one industry track where "full" cars can be dropped off and "empties" picked up, or vice versa. Every other car that leaves your yard will just be returning to the starting point. Oh, sure, you can mix the cars up in the trains that leave and return, but after a while, that will get boring in itself. Several more industries, and maybe even an interchange with another railroad, can surely spice things up!
Think about this concept before you invest a lot of time and money in a layout that may not meet all of your desires.
