So far, after much trying, I've found that it's $17.85 from Portland Maine to Boston. Cannot get beyond that, it wants such specific information, and won't give a schedule to guess from. You're not stupid, Amtrak's site is badly designed.

Mayb Sandra (Tattsxx11) would know Boston to NY train schedules? I know her husband sometimes works in NYC, but I don't know whether he drives down or what.
