John. It looks like you understood my explanation about placing the turnout on a grade in SCARM. Just be aware that during construction you don't want to start/end a grade at a turnout. As Mark will tell you, it's not easy to ease into or out of a grade to get a smooth transition and a turnout just complicates things. The main point of the exercise in SCARM though is just to see how things will fit, adjustments are always needed when actually constructing grades to get things to work smoothly.
Anyway, I took the liberty of further color coding the grades. This allows you to select them simply by double-clicking to check or change the grade. Color coding also lets you readily see where grades begin/end. I noticed the grade down to the bridge wasn't set and the yard area was elevated to 7", so I fixed those. Further, I know you're just playing around with things, but I'm curious how you think you'd use the long spur that goes just beneath the yard and the lone spur coming off the yard. I'm hesitant to fiddle with the yard design until I get a better feel for your thoughts.
