Beautifully composed image makes great use of the theme of this challenge. I love the pattern formed by the repeating arches and their clear reflections.
Nice image. And I like the lines.
I think it suffers from a bit of haloing, more so in the reflection, but there might also be a hint of it on the top too. The sky also (to me anyway) seems a bit grey. The kind of grey you can get when you pushed it in PP too much. Not saying yours was (it might be the weather on that day, so it's not getting knocked for it) but it just looks like that to me. It does have the benefit of not distracting you and making you look at the rail bridge, so, as I said, not counting it against it or anything.
All in all a 7 I think. Might bump it later. Might not. We'll see :-)
This is the interpretation of the challenge description I also took.
