Ned, a small engine and the turntable solve the alignment problem. Somewhere I have a satellite photo of the Amtrak yard in Maryland where they still turn the cars with a turntable that looks like an Atlas O TT and build the trains that way.
A couple of thoughts:
I liked the idea of shortening the loops and keep the orange line flat.Edit-not careful reading, I like the under and around.
Move the crossovers the turns at the end. EDIT: oops, I see that you can't because of the r-loop switch.
What did you use to make the r-loop fit. It doesn't work for me. Are the 1 3/8" half-roadbed pieces in?
I dont know - it just works - lol
I am using the remote switches with extensions from the Rail Modeler Pro Fastrack lib.
Here is a closeup of the section you are trying to replicate.
