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.

Looks like a headset jack under the console writing surface.

In any center with a similar function, the persons whose desks are closest to the screens are responsible for a subset of the system, (on the display in front of them). The person in the back (right of frame) is the shift supervisor.

I am told the original 1970s BART communications backbone was a single-sideband, frequency-division multiplex analog coaxial cable system akin to Bell System L-Carrier. If true, the SCADA and block signals all ran over the coaxial cable.
