Finished this first and have a few comments.
1} The coboose is reversed so that the porch faces the last car, easy to fix.
2} Is the any way to fic the awful sky dome besides DTG donig this? I have never seen the sun glow at 3:30 AM in my part of the U.S. And never have seen the sun rise at 5:00 AM.
Now for the good part.
A really fine route if a bit short, and great scenarios.. WELL DONE!!
