The Amazing Race: Train Edition

Standing in the middle of the train, I looked around me. First to the right, at the people around 1metre away from me, then to the left, at the people slightly closer, but still far from me. Is it because of my extremely sour face, I wondered. Or perhaps I have BO??? I took a few deep breaths. No, this isn't it. Ahh... A sudden realisation dawned upon me. That's because I'm standing IN THE MIDDLE of the train while the others are crowded around the train doors to compete for 1million dollars in a race to see who exits the train first!
