Even the ghost images appeared to pause long enough to leave a faint impression. I often wonder in this type of picture how many people were passing so quickly through the shot, their images weren't captured.

Hey! Photography is not allowed in Union Station. Stop that!

...And Fruit Skins. That signage made my day.

on the righthand side of the photo, above the entrance to where it says "To Gates 16 & . . ." They look like three huge TV screens but, this being 1921, they must be another type of screen that indicates arriving and departing trains, etc.

I love the look of the spirits in this picture. The sedate passengers appear as corporeal entities and the more active appear otherworldly, as if this were a waystation for this world and the next.

This waiting room is so distinctive and good-looking that despite 62 years between visits I remembered it well.

In 1942 I was six, but in 2004 failed to take a photo; maybe someone else will show us how it looks now, especially the way there are dining areas that extend into the room.

There must've been radiators hidden behind the screens at each end of the benches.

As an example of post-9/11 mindset, I found myself searching for unattended bags. I think I see one.
