I know you know, but Shorpy is king

Was scrolling through during a boring call yesterday and came across this:
https://www.shorpy.com/node/26003

But it reminded me of how incredible that entire site is, especially this tag:
https://www.shorpy.com/historical-railroad-and-train-photos

It is probably responsible for 30% of the contents of my "rotating wallpapers" folder on my mac.

The Jack Delano photos always get me, especially those taken inside the roundhouses. Such great atmosphere in those images.

The Marion Post Walcott stuff around Pittsburgh is awesome too:

Yes, Shorpy is an excellent references site (and just to look at some random vintage photos for fun).  I used to visit there regularly, but I haven't been there for some time.  Need to go back.  IIRC, The Library of Congress also has a nice section of photos.
