One-One

You were a passenger who had just entered the train and had the number "437" in your hand and to get off the train you needed to go down to number "0" through the cars learning lessons and doing good deeds, although you could also go up if you did the opposite While passing through one of the snowy forest-themed cars you stumble upon One-One who was buried under the snow It turns out that One-One was wandering around the thousands of cars, apparently leaving his responsibilities as an engineer aside.
