I have been looking for this shot in the 285 entries and here it is! and it is just as good and interesting as I could have imagined. Very good technically, too.
A good, original compositional choice. The colors look like it was shot with dyalight white balance in tungsten illumition. the effect is very nice, wouldn't change it.
This is my favorite of all the train wheel photos of this challenge, lighting and coloration give a sense of richness of days gone past (when riding a train was a luxury). Great shot.
