Question: Can you reach all the tracks for the inevitable derailments, etc in "bad places"?

Suggestion: I'd cut out about 30% of the trackage, or at least plan to add track in stages. I think you'll find the cost and maintenance to be more than you expect.

IME, the more time I have to spend cleaning / maintaining something, the less likely I am to keep using it. But I'm lazy and a lone-wolf, so...

Use the existing bench on the right as stub-end staging or a large industry like a papermill or refinery. Mainline runs on the big rectangle. Then you can also ditch the swing / duck / lift section. Run a scenic divider down the middle of the 5X8 lengthwise.

Just tossing out random ideas...
