SF ... industrial? As a practical matter, SF has been a net consumer of everything since the 1960s at the latest. Warehousing in SF was for import/export (while the port was still working) and local consumption. Practically nothing was produced there for shipment elsewhere. SSF was "the industrial city" but by the 1970s about all they had was office and warehouses, again mainly for local (especially SF) consumption. Actual industrial production centered in the East and South Bay areas long before the middle of the 20th Century because they were just easier to reach. Feinstein may have given what little was left a gentle push, but industry of any kind was basically gone from SF and most of the northern Peninsula well before her reign.

Once offices and software companies became the primary form of gainful employment in the 1980s (supported by BART and Caltrain hauling in commuters), about the time most of the Belt Rwy shut down, it was all over but the (railfans) crying for anything in SF that might have really needed rail service. All that's left are a few niche freight customers and commuters.

Amusing that the biggest rail-port loads in recent years were the America's Cup yachts - actually required reactivating tracks on one of the docks near Islais Creek. Kind of tells you what the main product (other than some mind-altering substances and software) is in SF these days: cubic $$ and b******t. Don't need a railroad to haul that any more; just suitable internet access.
