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 San Francisco cable cars are the only moving National Historic Landmarks. 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. Cable cars operate on two routes from downtown near Union Square to Fisherman's Wharf, and a third route along California Street. While the cable cars are used to a certain extent by commuters, their low speed, small service area, and premium fares for single rides make them primarily a tourist attraction.
