Branch line/ISL

If your plan isn't "cast in concrete" yet w/ glue & ballast, here's a few revisions you might want to consider. Put the run around along the ladder & put the engine house to the left. Both gives you more useable yard tracks.
Moved your industry on left to other side of the spur. That way you don't have to reach over/around it when spotting cars.
To avoid having to handle your rolling stock alot. you might want to think about some kind of portable tray system for your interchange/staging track.
