At nights in the summertime I heard lonesome whistles blowing, and dreamed of taking the train to the future. To romance. To the rest of my life. Or just simply out of town. Trains embody the fact of travel, the sense of moving through time and space and day and night. Airplanes are elevators whose doors close and then open in another city. The two Japanese kids in Jim Jarmusch's "Mystery Train" (1989) have the right idea. They're on a train to Memphis. With one suitcase suspended on a pole between them, they wander the bedraggled streets until passing by accident the door of the Sun record studios, which is a shrine for them.
