I made this more for myself than in actuality because I was having a hard time visualizing where the RoA was now that they are stripping out the tip of Tom Sawyer's island.
Pink is the old route, purple is the new route. Teal is the old train route and light green is going to be the new train route.
Here just a larger zoomed out view without the markings...
I'm actually shocked how insignificant the change is. If you ask me, the small alteration in RoA was really for the railroad's sake to take its more windy route.
