Paul,
ok, 10"s everywhere. One more item...the switch at the top of the grades. I was thinking of two options:
Option 1
moving it past the junction to the left, over the tunnel. That would have it supported on the elevated deck.
But, two concerns
1. Coming from the outside loop and switching in top the start of the r-loop it would be a wiggle and then a turn.
2. Difficult to make a bridge for the two tracks coming together.
Option 2
Move it one straight towards the door. Then, build something like a butte for it to sit on at 6.5"
This wouldn't affect the grade much and leave a single straight for a bridge crossing over the junction. Most of the train would be straight and then enter the first turn for the r-loop. ( now a balloon)
What did you have in mind for supporting that switch?
