How does the author use foreshadowing in The Switchman?

Arreola uses symbolism, particularly with the character of the switchman, who carries a "red lantern but so small it seemed a toy." The lantern is a switchman's tool, but its small size indicates the man's lack of any real knowledge or power. This also serves as a method of foreshadowing, indicating that the switchman will tell outrageous stories, and the meeting between the two men will become almost like a game that no one wins.
