If you can find a gas station in the middle of a huge desert you should be able to see a train station just outside of town. I'm not sure what you meant about sf since you can only find it by doing the whole tour from VC.
Aye never really does make sense.
Now seeing as we're following the logical train of thought, why isn't there some form of train timetable available at each station?
It certainly would help, but seriously I mean if we can still maintain a train then whacking out a timetable should be a cinch for them. Hell if there that stingy on paper how about a holodisk you can buy from each station that puts a copy of the timetables in to your pipboy.
