Why does going backwards on a train make me feel sick?

Some individuals feel dizzy and nauseated if they sit on a backward-facing seat on a train because of the conflicting cues from the eyes and ears regarding motion. The eyes are unable to see and predict the movement while the vestibular system in the inner ear which helps in balancing can sense motion.

Is it safer to be sitting the way train is going or vice versa if the train crashes? Facing backwards is safer. In a crash the train will decelerate quickly. If you're facing forwards this will throw you out of your seat, if you're facing backwards it will press you into the seat.
