The nation's only moving national historic landmarks,
the cable cars still run on 8.8 miles of track along three of their original hundred-year-old
routes. These motorless carriages travel by gripping onto the constantly-running
underground cable on the ascent and releasing on the descent. Average speed: 9
1/2 miles per hour. Steepest grade: 21.3%. There were 9,600,000 cable car riders
in 1995-1996. Hyde Street Pier, Alcatraz in background. SFCVB photo by Phil Coblentz.
