Meaning of "This Train" by Peter, Paul & Mary

The song "This Train" can be interpreted as a metaphor for life's journey towards salvation. The train symbolizes a path to righteousness, with the passengers representing different aspects of one's past and present. By excluding gamblers, jokers, and other unrighteous individuals, the train represents the idea of leaving behind sinful behaviors and influences. The mention of loved ones being carried by the train could signify the cycle of life and the inevitability of death. Ultimately, the train's destination of glory for those who are holy suggests a religious or spiritual message about the importance of living a virtuous life in order to attain salvation.
