The San Francisco cable car system is the world's last permanently operational manually-operated cable car system, and is now an icon of the city of San Francisco in California. The cable car system forms part of the intermodal urban transport network operated by the San Francisco Municipal Railway, or Muni as it is better known. While the cable cars are used to a certain extent by commuters, their low speed, small service area, and premium fares make them primarily a tourist attraction.
