"You can be sure if it's Westinghouse."

Handset cords that retract into the console are part of what's called a panel phone. Single speaker with volume control was possibly for the original VHF conventional simulcast train channel on 160.410 MHz.

Guess: is that Rohr's Arriflex 16mm movie camera?

Me: "The BART employee appears to be reading a printout inside the acoustic cabinet and taking notes with a pen. That's how it was done in 1974."
My friend: "That, and five dollars, will buy you an espresso drink at Starbucks."

In 1974, there were no flat panel displays. It's unclear what display technology was made to look like a flat panel.

Westinghouse also built and sold power reactors and some of the expertise that made these consoles my have come from that division.

This position has a red handset that is not present at the other consoles. My guess is that it's an elevator emergency phone. When there's a problem, the phone in the car might ring here. BART initially had a fire crew which (I believe) was for the Trans-Bay tube. It may be for fire dispatch. I think they've always had an auto-aid agreement with SFFD and Oakland but in the early days they had one BART high rail fire vehicle.
