Nothing "artificial or processed" about them other than the slightly
high exposure. I have seen photos of the same trains where they are
grey looking, not black.

OK, different to what I might expect from UK trains.

eg: http://static.panoramio.com/photos/original/7485937.jpg (by John
Flint). There is another photo I've seen where the trains are near
silver-grey looking.

Looking at the images I posted above there is quite a range of black to
grey ... that's what the camera recorded.

OK.

Well printing really makes you get all the light you can so that you can
then compress it into the range of the printer. Dead black is passable
on a print - dead white skies really kill an image.

Interesting. Is the effect of a white sky any less if the print is
borderless?

Cheers,
