It has occurred to me - belatedly, I'm afraid - that if you're interested enough to read some of these posts, I can certainly take the time to answer any questions you might have about train travel.
I've been a passenger on every one of Amtrak's long-distance trains, most of them a half dozen times or more, and most of VIA Rail's trains in Canada. I won't have all the answers, but will do the best I can. At the very least, I'll either refer you to the right source or dig up the answer for you.
If you would like to contact me, please feel free to do so at firstname.lastname@example.org or by using "comment".
