The quote from Toni Morrison's "Beloved" reflects a deep yearning for solace and peace amidst turmoil. The imagery of laying one's head on the railroad line suggests a longing for escape, using the train as a metaphor for a fleeting moment of tranquility. It captures the idea of seeking comfort in something greater than oneself, even if it's momentary.

This phrase reveals a character's struggle with internal pain and the desire for resolution. The train represents not just movement and change, but also a way to find mental relief. In the context of the novel, it highlights the impact of trauma and the search for healing through connection to external forces.
