Silver Belle Run

It all started innocently enough, looking at a puzzle by Ted Blaylock called Silver Belle Run. There it was, a crazy thought that it would be nice to have a railroad built around Blaylocks series of train puzzles.  Not that I could pull that off, but I have never liked the fact that I can't follow my train around the middle peninsula, as it goes through a tunnel back to the other side.  After a couple of false starts, I came up with the plan to use a loop back behind Cave Junction, connecting to the logging branch. This loop will have a place for the stone bridge featured in the puzzle, now how to build it.

The track loops around through the wall and back out on the right side of the picture.
