The booths in the diner cannot be adjusted. If she is concerned about her size, she can ask her SCA if she can have meals delivered to her room. For what it's worth (and you can share this with your friend), I could sit in the diner just fine when I weighed 300 pounds (I'm 5'6"). I carry most of my weight in my lower body. It was pretty tight when I was 315+, though.
Nobody ever brought up my size while on the train, and there have always been people bigger than me, even when I weighed over 350 pounds. Amtrak is nothing like the airlines.
If she's on a Viewliner, she will have a toilet and sink in her room.
If you have sleeper accommodations traveling to NYP, then yes, you can wait in the lounge, even if your connection is Coach. We do this all the time in Chicago. We have a sleeper on the Southwest Chief and then regular Coach class on the Wolverine.
