zombie apocalypse on a train.

The zombie apocalypse had begun, a couple of zombies were chasing you, you were running from them through the forest, branches mercilessly scratching your face and exposed parts of your body, everything was swimming before your eyes, you thought this was the end, but suddenly... you came out onto the tracks! Where the train was parked, it looked old, you immediately ran in there, abruptly locking the door, a second later you heard scratching, nasty slaps and other sounds behind the iron door, only it separated you from being torn apart, the train was completely at your disposal
