TREVOR'S SWITCHING PLAN
Here's a few revisions to your plan in response to some comments & my ideas. The engine service track is now on it's own vs off a wasted lead. Also there are 4 yard tracks + the interchange track. Or you could use the top yard track for unloading covered hoppers for ADM. The track next to ADM could be used for loading the processed flour into boxcars &/or airslide hoppers. Also mills like ADM ship out the bran for animal feed. Moved the switch to the plastics place on the curve to get rid of the S curve leading into it. If your plastics place has inbound (pellets in hoppers) & out bound traffic (bags, boxes, etc) add a 2nd track off the main for that. That way you won't have to move cars out of the way all the time.
