That happened to me years ago when I took an overnight train from Paris to Zurich. Problem was I didn't speak French and I didn't understand why he took my passport. Because I didn't know when I would get it back (eventually I did many hours later a few minutes before my final stop), I didn't sleep at all that night because I was worried about not getting it back. Wish I had done a little more research beforehand (and spoke French!).
