Folder: S.F. Bridges-Bay-Trains. Newscopy: "Opening a new era in San Francisco-East Bay transportation, the first Key System trains to 'officially' cross the bay bridge are shown discharging their passengers here at conclusion of the dedicatory run. Loaded to 'peak hour' capacity, three trains, including a Sacramento Northern, came across the bridge in a leisurely fashion, taking 28 minutes for the trip."
