You are inside the tail car which are where 3rd class passengers are placed in,which is extremely poor & messy as the snowpiercer,the enternal engine,which is a locomotive that will never stop,onward down the tracks of this frozen tundra of the freezing cold & frost covered envoirment of earth,which is within an enternal winter. You sit in one of the free shelves in the tail car, and multiple other 3rd class passengers try to find a good spot to sleep as you shiver from the cold.
