The wife and I were going to Kansas City on SWC to see some friends about four years ago. We were seated in the diner with this a middle aged man and wife. I got the impression right away that she didn't care for Amtrak travel as she was reasonably friendly but kind of snippy. He said very little other than what he did for a living and where they were going. My wife was right in the middle of saying something, (as we were doing the our best to keep up the conversation), when the woman looks up at the celing of the diner and shouts very loudly, "WILL YOU CUT IT OUT!" My wife and I looked at each other in shock that somebody would shout that loud in a public place let alone in a 'dining atmosphere'. The woman quickly recovered, smiled strangely and said, Oh, sorry. I was talking to the train, I'm tired of getting bumped around." Needless to say we ate and beat feet out of there!
On another note, when I was in High School, (returning home on the SSL/TE w/my parents), I met a wonderful girl who was traveling with her family in the same sleeping car. They were from Yuma AZ and were going to attend her father's reunion or something like that in Chicago. We hung out in the vestibule for hours after dinner, (on the SSL portion), until each set of parents hinted it was time to go to bed. Ultimately we kissed and hung out together, (now on the TE portion), for the rest of the trip. We did not get to sit together at dinner but her family was diagonally across from mine so were able to smirk and make eyes at each other while trying to be 'cool' in front of our respective families. We did stay in contact via letters and calls into our college years, (this is pre-email and massive cell phone availability of course). I never did see her again after that trip but we sent each others pictures and it was fun to have a cute pen pal in AZ for almost seven years. Thanks Amtrak!
