I'm perfectly comfortable on a train but also don't see why you're being downvoted. If you have a problem, you have a problem. That's too bad. Me, I knew a person with an inner ear disorder that caused dizziness, who had no problem on trains. And on the other hand, I knew a dog who threw up in any car. So you encounter all kinds of things, it seems. I've heard that seasickness is caused by a mismatch between what the vestibular system senses, and what the eyes sense. So, on a boat, you don't go belowdecks; you go up top and keep your eyes on the horizon. I wonder if even just looking out the window more would be of any help to you.
