Hi Stephan, fantastic shot. The combination of the setting sun with the silhouettes of rail side details (quite an industrial atmosphere here!) is amaising. Very well captured, and excellent tones.
I think the left side of the image is a bit redundant, as I feel it doesn't add too much to the composition and the atmosphere. I cropped a bit off that side, hope you don't mind. Maybe it makes the composition a bit too static, but as I like the close composition on the right and bottom side, I tried to do that on the left side too...
