All the plans are in the same scarm file posted. Look under the layers tab. The original layout is under the layer 0 tab, plan 1 is under the alt1, plan 2 is under the alt2 tab.
The location of the entrance to the yard is just for an example.
A couple of questions:
How close to the edge of the platform do you want your track?
Is it different on the wall sides versus the non-wall sides?
can we bump out the front left area of the layout to stretch the far left curve to O60?
does the bridge really need to be 7 inches high?
