This map is vastly superior to some of your earlier drafts - you've done a really good job here.
The only things that I would pick up on are as follows:
1. The railroad border between Swan Island and University looks a bit out of place, given that it is so short and doesn't connect to/with anything else. I think you could quite easily lose that as an impassable without any detriment to gameplay - the other option would be to link the railroad to another track, but that would be really difficult on the eye.
2. There appears to be a slight inconsistency with the thickness of you territory border lines, and personally I think they're a little too thick.
3. The lakes at Goose Hollow and Clinton appear to be raised up from the ground rather than sunken in. On the subject of strange bevels, the Picnic table at Mt Tabor looks strangely out of place... I get that it's supposed to be on a hill, but it might be more in keeping with the rest of the map to flatten it out again
4. At first glance, the blue MAX line looks like a river in the Beaverton area - is there any chance you could add a drop shadow in the same way as you have done with the road/bridges? I think the real concern is that the dedge by Beaverton is a bit fuzzy, and not as crisp as I'd expect it to be.
5. The MAX station numbering doesn't appear to be very logical... Is that how they're numbered in real life? If not, then I'd suggest renaming them as follows: 8->1, 7->2, 4->3, 3->4, 2->5, 1->6, 5->7, 6->8. You've also not labeled TC anywhere - I'm guessing it's inferred by the circle symbol - but it might be worth adding TC to the legend too
6. My final thought, is that the road/bridge between Terwilliger Curves and Reed might look a bit better if it was angled up slightly, to be vaguely orientated with the other bridges - this is more for consistency than anything
As I said at the beginning of this post; the map is looking really good now.
I don;t think yiou're too far from getting the graphics stamp now
