For some reason, the signals at this intersection in Ashland, VA are set up with one light of the rear lights turned 90 degrees. I'm not sure if is for the trains, or possibly because there is a road that runs parallel on both sides of the tracks.
Whatever the reason is, I don't like it. It looks crappy in my opinion!
There's a few other intersections like this too, but not all of them.
