Passengers in Peril

You and your group were at a party in downtown New York. Everyone took the subway there and back. On your way back, your train becomes derailed and slides violently down the tunnel. You and your group are the only survivors. With no food and no service, you manage to walk your way to the nearest subway station. Unfortunately, the station is completely abandoned and worse yet, the tunnel behind you has caved in. Can your team use the only remaining train to escape before you succumb to the lack of oxygen… or something worse?
