I would like to ask what are those lights appearing as a town almost suddenly from the nothing in the window of the night train. Everywhere is dark but you can then see a galaxy of bright yellow lights. The first thought goes to San Francisco, or New York City, where the lights define the shape and the form of the buildings, the color of which merges with the one of the dark sky. But then you get nearer, you pass an empty bleak station with no roof, but some grass even where it would not be expected to be. And you see a name: Leuna.
