Assuming I felt well and it was just an inconvenience, I feel like I could deal with it ok. I’d pass the time talking, working, or reading. I didn’t notice if they had electricity to charge their phones and computers. Since it’s a vacation type ride, I’d assume I had stuff with me to make it bearable.
If I was sick, and counting on getting out at a stop to get medicine or supplies that would be a different story. Or, if I started to come down with an illness during the 36 hours I would be pretty upset.
Once the heat stopped working, if it became very cold on the train, that’s when I’d start to be miserable. Sounds like they had heat most of the time. As long as there was some food I’d be fine. Missing a meal or two wouldn’t bother me too much, as long as there was plenty of beverages to keep hydrated. If food wasn’t plentiful, I’d eat a little here and there like snacks assuming the food would keep. I’d drink sugary sodas or juice for calories if they had that.
Also, if I had young children with me, that would be really a challenge I would think.
As far as the students with tests, I would call the dean directly. That’s ridiculous. I really doubt they weren’t allowed to take their exams. The professors are being idiots. This isn’t cutting it close by flying in the same day as a test, or even the night before. A 36 hour standstill is highly unusual.
At least on a train you can stand up easily and walk around.
What compensation are they getting? I’d want a refund and some extra money or free train rides or something.
