Be sure to join Amtrak Guest Rewards, so that you can get some benefits from your train travel! It's their "frequent flyer" program.
I'll 2nd THAT ! I get a lot of free trips using points. I use the AGR MasterCard exclusively...all others are just for emergency. I generally charge over $5k/month on it and accrue points, and QTPs which establishes your "Status" that gives you even more benefits. Yes...you have to read the rules closely as the $5k/month thing is limited, etc., etc. For the ol' timers...don't'ya miss the old system where "points" weren't "dollar-related"!?!? Man, did I work that! "Oh, use my points for the trip back (more expensive in $$$) and I'll pay cash for the trip down (less$$$)". LOL
