Thanks Jumijo, I am keeping it simple like I did on the last layout. The old Greenbrook layout was influenced by my time with the Glancy modular layout. At the time I had an O31/O54 apartment layout and I always liked it when we would just set up a big oval with O72 curves. Big stuff just looked and ran better on the comparatively wider curves. The long straight shots always looked good too.
I considered an over/under design but I just couldn't resolve the grades. I wanted to keep them under 2%. I think the slight grade separations are just enough to add some scenic interest without making an operational headache.
I am hoping to finish tacking up the backdrop this weekend so I can move onto patching the seams and painting...
