Dead rails.

It's only the three of you. You, Isagi, and a man named Luke. Then, after three nights, Luke got caught and was eaten by werewolves.. You and Isagi shoot those wolves but don't have enough time to save your friend.

Five nights after his death, it was silent. Isagi was driving the train, while you're outside holding your gun, preparing when there's zombies nearby. You both don't have food and resources, and was planning to stop by at a town.

It was still in the middle of the night as he continued to drive.
