Billie Joe’s son went to school with “Train,” who was raised by two women. Throughout the song, the narrator eludes to the general feeling of uncertainty surrounding this character. As a child, the character did not have control of his life, and was forced to roll with the punches, “like a rat inside a maze.” This carries strong meaning because this high degree of uncertainty isn’t usually part of a person’s life. Now, the only choice “Train” has is to accept what he’s been through, and wonder where he’ll be tomorrow. The song is completely summed up in these lines: “Don’t know where I come from / But I know where I have been.”
