Understood, which is why I decided to make BWI my 1/4 and 3/4 stop. It's still only 13 or 14 minutes from BWI to and from BAL, but I figure the conductors are more accustomed to people hopping on Amtrak for that run. And Baltimore Penn Station is a much nicer place to wait between trains than BWI's Amshack.

I did check prices for one ways, and they're about twice as expensive. Amtrak seems to be leaving some money on the table with this multi-city fare--but the railroad has already done well by me this year
