A winter storm has just blown through the San Joaquin home port of Oakland on February 16, 1991.  Sitting in front of Southern Pacific's 16th Street Tower is an Amtravel bus silently waiting for it''s next train of passengers to arrive from the Central Valley.  This is Amtrak's San Francisco connection which ferry's ticketed passengers across the Bay Bridge to the Transbay Terminal, Amtrak's designated San Francisco station.
