Did the engineer know where love goes when it dies, or how it was possible that hummingbirds can cross the ocean while words can fail to fly half a pillow's distance? And on those cold winter nights when snow obscured the tracks, did he ever lose faith? That the rails would still be there, that the bridges would hold, that there really was a Vermont, that there really was a train, and that the clickety-clack he heard wasn't just the sound of his own heart moving away from him in the night, growing fainter and fainter, beat by beat.
