Meaning of "Refrigerator Car" by Spin Doctors

The metaphor of a refrigerator car is used to depict a person who is emotionally closed off and unable to love or feel deeply. The lyrics paint a picture of someone who is detached and frozen in their own emotions, carrying around a heavy burden of unexpressed feelings and unfulfilled connections. The description of the heart as a "frozen freight" symbolizes the emotional baggage that the person carries around, unable to let go or open up to others. The idea of the person rolling across the desert and clacking across the sand suggests a journey through life devoid of warmth or emotion, with relationships and experiences crumbling around them. The imagery of grey ice in the hinges and sliding doors shut frozen locked signifies a complete inability to open up or let anyone in. The final lines about blowing one's brains out with one arm and digging a hole with the other speak to a self-destructive nature and a lack of true understanding of one's own emotions. Overall, the lyrics convey a sense of loneliness, isolation, and emotional paralysis.
