Today I completed the mainline roadbed on the layout:

One thing I’ve read several times online by other modelers is the how overly wide the cork roadbed is, and I think I agree.  Having the roadbed beveled right at the edge of ties seems to give you a cleaner, more prototypical looking ballast line.  So once I get track curves shaped, I’ll mark the tie edges on the cork and trim the edges to narrow the roadbed.
