If image were a little less dark showing a little more detail, it could very well be a great advertisement. Unfortunately, a great idea and composition is flawed by it's unclear nature. The image appears flat and not particularly interesting in terms of color. It might have helped to use a little better aperature control - it's almost as if this is a straight auto shot which is never a good idea in this kind of light. A good idea just short of being a great image.
My initial impression is that it's just too dark, but when I stop and think about how the sunset reflects off the tracks so that really all you see is the orange glowing tracks heading straight toward the sunset... it's really cool!
