Shin Seizonritsu 0%! Chikatetsu Kara no Dasshutsu

Midnight. A last train. Fourteen strangers board with their own reasons for being there. Somewhere along the route, one of them kills another. The culprit is sitting in the same car as everyone else. With the train still running and nowhere to go, the only thing left to do is find out who did it before they do it again.
