I liked Burkus' design on the first page, I have done many designs with similar features and posted on the forum, but not a 8x10. Constructed with a 4x8 and 4x6. I worked with his design and eliminated the reverse curves, and then added a run-around track spanning the yard.
I also added a few industry spurs. One can do without the run-around track for longer yard spurs if desired. Delete some industry spurs if it looks too busy.
