13. When laying cork under switches, the easy way is to get cork sheets and cut and lay them separately. If you prefer to cut and blend the cork strips through the switch zone, first lay down the outer strips for the diverging routes. Then cut, fit, and glue filler piece(s) afterwards.
Thank you KD. I would add that Atlas track can be temporarily screwed in place with the outside edge of a curve for example along the Sharpie center line. This makes a good backstop for the first cork piece. Remove the track and then lay the second piece.
On cork under switches, would love to see that done right in detail the way you describe. The way(s) I've been doing it are a PIA and every one seems to come out a little different.
