I think this song is about a person standing on a train platform after a painful breakup. The bag contains all of their worldly possessions. They realize that this relationship once seems like a good thing but now is end for them. On one hand it seems like the act of getting on the train may be the step they can't take back but I think instead this person is thinking of stepping in front of a moving train to end the pain by committing suicide. I guess for me that is the only confusion is the last act ending their life or simply leaving this relationship that has them feeling pain so bad it cuts to black.
