The train is barreling down a track with five people tied to the rails. It crushes them. You hear the screams and watch the blood spurt and then dribble. Ahead are another group of five people on the rails. You can let the train continue on its murderous path, throw a switch that will shift it onto a different track but cause another train to run over the people, or you can go call 911 because the people are going to be crushed no matter what.
