Where the hell is the train going? It is mercilessly, tirelessly chugging away - but it does not know which station it's going to. The train has no passengers in it. It's travelled tons of places but it has no idea where the next stop is. Neither does it remember the places it has been to. All it's doing is burning coal and steaming away. It's as good as an empty boat left to flow along with a slow stream of water.
