In this passage, the little prince observes a busy express train and questions the switchman about its purpose. The switchman reveals that the passengers inside are either asleep or uninterested, highlighting a disconnect with life as they passively engage with the journey. This reflects a theme of adult indifference, contrasting with the curiosity and enthusiasm of children.
The little prince notes that children have a unique understanding of what is truly valuable, illustrated by their attachment to seemingly trivial objects, like a rag doll. This attachment is significant and evokes strong emotions, indicating that children find joy and meaning in their simple pursuits. The switchman acknowledges this simplicity as a fortunate quality, further underlining the contrast between the innocence of childhood and the somber passivity of adults.
