The reference to "age lines" and "gripe lines" suggests a profound weariness that comes from life's challenges, much like the deep railway tracks depicted, symbolizing the inevitable passage of time and experiences.

In "Snow in Summer" by Jane Yolen, this imagery highlights the tension between appearance and reality.

Ultimately, the author conveys that no amount of superficial enhancement can truly conceal the depth of one's experiences and the truth of aging.
