Mallard, I have a question. You say you can't mix 031 track with 027 track. Why? Are you saying that I can't have a layout with an outer loop using 031, which switches to an inner loop that has 027 turns?
Geez. this is really complicated.

O and O27 tracks are different heights, and O gauge track pins are a larger diameter. Connecting them together CAN be done, but it's more work than it's worth.
