Moonlit Rail ™
Recognize this photograph? It was used to make the background imagery that adorns Moonlit Rail's default website page style. As you can see, it has been deliberately under-exposed so as to allow it to be composited along with the moon and other elements.
If you have a look at the next photograph in the "Miscellaneous" sequence (same track but looking in the other direction), you can see the actual lighting conditions that were present that day.
