On the other hand, a café car purchase on a San Joaquin did post at 3X, although I don't know if it was travel or dining.

There's apparently no wiki due to this series of posts being moved but perhaps there's some value in listing out the specific Amtrak lines and how they're counted by Chase. For what it's worth, when I added Amtrak last year the Pacific Surfliner (San Diego-LA train) was one of those that counted as travel.
