Sunday morning I rode the Northeast Regional from NYC to BAL. It was the 143, leaving NYP at 9:47 AM. As we left the station I was disappointed to see that we were riding backward. At first I thought it was just our car (business) but then they announced that the entire train was backward and apologized. I asked the snack attendant why they might have done this - like, did they not have the time or space to turn it around? But received no answer. At first I thought it was okay, and tried to enjoy the view, but about halfway through the ride, my companion and I both admitted we were feeling some motion sickness.
I have never encountered this. Why would they do this, and is this a common occurrence? I sure hope not.
