to me this song is about a person struggling with a breakup and he constantly is being reminded by old pictures of the bitterness. "I turned you in I turned you into whispers " seems to be about not letting the bad thoughts get to him, and not letting them control him he's breaking away from the normal and going down his own path and trying to grow. The "i remembered you on trains so now your on every train i hear" seems to be refering to the past when he used to be "in love", but now all the old pictures and trains just remind him of his ex- and it's difficult to move on, so all the thoughts and voices that cloud his mind and remind him of her are just turned into whispers so he can survive.
