Insomnia makes sense...and one problem with being on the train is that if you get insomnia, there's not a good way to "exercise it off". Also, it's quite possible that he was able to snag a lower-bucket roomette. Finally, there are times I can see myself grabbing a low-bucket roomette on a run even during the day...particularly if a sleeper is in low bucket mode, coach is in high bucket mode, and there are meals to be had. Note that, in theory, the net cost of a sleeper (roomette cost less the base ticket cost cramdown) on the Cap might be as low as $70 even now. At that cost, I'd seriously look at grabbing a roomette for a very long daylight run.That could explain the actions of the passenger from South Bend. The hard part is trying to explain the constant surveillance and concern between the OP and the SCA. Even though nothing bad actually happened that doesn't seem to have changed the OP's opinion about the experience in the slightest. It's almost like he still thinks he just barely made it out of there alive or something. I also don't understand the criticism of the stranger's supposed extravagance of purchasing a roomette and leaving it in day mode when the OP himself is a single passenger taking up a whole family room. I agree that there are a lot of strange things about this story but most of them seem to have little or nothing to do with the passenger from South Bend. Situational awareness is a good thing, but it can get the better of you if you let it. When I close my curtains it's not the briefcase toting insomniac that I'm trying to avoid. It's the self-appointed hall monitor with nothing better to do than watch what everyone else is up to.Maybe he was suffering from insomnia. Just a thought.not in coach, but in a sleeper on the Capital Limited, we had a passenger who boarded in South Bend, and told the SCA to not lower his bed, every hour or 2 he'd come out of his room fully dressed, go somewhere for 5 or 10 mins, then come back to his room, sit in his chair clutching his briefcase and closed the door. The man never went to bed, never made up his room, never even turned his light off that we could tell. It was like that all the way into DC. Even the SCA was getting a little freaked out by it (this wasn't too long after 9-11). I have no idea what it was all about or what his story was, but he could have just bought a coach seat and saved high bucket price. I was in the family room (solo)and he was he in one of the downstairs rooms also. The whole thing was very.. very.. strange to be honest.
My guess with the OP is that he knew the SCA from a number of previous runs. Believe me, this can (and does) happen when you regularly travel a route.
