Paul,
I have to pack the computer for moving tomorrow, so here is my last idea to think about.
The thought process behind my track diagrams is to get the trains coming from the outer mainline on to the inner mainline, through the reverse loop, and off of the inner mainline as fast as possible.
With this in mind, I added a double slip switch to the left leg.
Pros:
- This is the closest point to the beginning of the reverse loop that the outer mainline can be.
- Trains departing the yard area can be quickly reversed and enter either the inner or outer mainline.
Cons:
- The lower level will be closer to the upper part of the layout.
- In order to accomodate the extra space, the curves will need to be O-72 on the outside mainline and O-63 on the inside mainline.
Again, this is something for you to consider for efficient reverse loops.
