The Coronation Scot

Thank you, Hondo, what beautiful posters in that video.

I thought it was the Dutchess of Hamilton but the door hardware did not match the Dutches in the museum.

My sleuthing skills failed me on this one. Good job matching it to the Coronation Scot!

Must be a great accomplishment to get a train out and onto the correct track in that can of worms. Looks tougher than an air traffic controllers radar screen.

This will FRY your socks. There are some C. S. near the end.

I hadn't thought of that. You make a really good point. I took the skills involved in a train traversing that gaggle of switches for granted when I saw that picture. Thanks for the heads-up, Mitch. I like how I often learn something when you make a posting.

Remember it's a guy back in a tower throwing electrical switches or moving a lever of some kind that lines up all of that track for the train engineer to take his loco through. If he doesn't get it right, interlocking connections in the tower will not let it happen. Of course the engineer can still screw it up.
Very simplified description. An old Trains mag had a great article on how it was done.
Almost every major station had a mess of track that looked like that.

And my Thanks to you, too, Roger. It's good to learn stuff that is new to me.

Thank you E7. My socks aren't fried but it was interesting to see a UK 1/43 model railway bigger than a shoebox.

Sulfur deposit.

No, not sulfur, another mineral. There are two possible answers, name the mineral or name what it is used for.

carnotite

That is what I thought at first. Arizona has tons of carnotite, mostly on Indian Reservations (why there?).
There is a clue just above the whatzit mineral indicating it is not carnotite.

Next clue:

Petrified tree......Copper ore

One of your guesses is on the right track but is not the whatzit.
