after being outside of your hometown for a long while, you're finally coming back, you're currently on a train, on your way there, it's pretty silent, there's basically no one there but you, but you don't mind it, but still find it a bit odd

Suddenly, a loud thud is heard and the train stops abruptly, almost making you hit with one of the seats infront of you, you stand up in confusion, not knowing why that happened, but it seems to be that you have been trapped in this train, at least until you find a way out..
