I played around a bit tonight and I think I am pretty close to what the final plan will be. I think at this point I just need to mock up the structures and sit them and the track out on the modules to get everything finalized.

Original plan with lost of nice scenery etc added:

 Revisions from tonight:

The coal dealer will be in the bottom left now and hopefully will become a coal and fuel dealer with a tank car spot just off the turnout. I'll have to see how it works out. The lumberyard moves to the upper right. There is now 2' past the upper left turnout, which should leave space for a steam engine and a car or two to get up there. With the staging extension on the lower right, there is plenty of space there as well.

Let me know if you have any feedback or suggestions!

Thanks!
