Ok, might swing by this weekend if I have a chance!
Wasn't the best day, and when I got home I found out that a bunch of the info placards that would be readable... weren't.

Went ahead and put them up at
https://flic.kr/s/aHBqjC6zb4 for you to look at (and if there's any specific ones you want to read, I'll see if I can go back later); in the meantime, here's a few selected ones for everyone.
Establishing shot: Exterior, overcast and grey.

There's several of these mash-up sculptures in the plaza outside Union Station; I think they're kinda cool, though I wish the sculptor had picked a more savory airliner than the DC-10.

The station interior was made back when train stations were a monumental undertaking, instead of a rat's warren. Thank goodness.

After sitting derelict for more than a decade, the station was saved by a proposal to turn part of it into a science museum. Welcome to Science City!
