I'm pretty sure there are more than 3 that get "within a reasonable distance to the boarder" A good portion of the Wolveriene is withing 100mi of the border (although I have yet to see BP on it...) Even the Blue Water terminates within 100mi of the border.Except for 3 routes (LSL, EB and SL) you should not see BP at all on the trains (except of course the trains that cross the border).
When I took the EB to pPortland we were questioned by BP. We were traveling with a friend of ours from India and the stoped us and had loads of questions for us, the two officers didn't think that someone on a work visa could go from an office in Boston to visit one in Portland, OR by train. I think we made the train about 15 mins late. Interestingly there was a man in the same car as us on a tourist visa here from Nigeria who that barely even looked at (asked for his papers and nationality and then moved on) Our return trip was uninterrupted by BP (although we did have a "run in" with the local police when out train almost hit a car parked on the tracks.)
