The San Francisco cable car system is the world's last manually operated cable car system. An icon of San Francisco, California, the cable car system forms part of the intermodal urban transport network operated by the San Francisco Municipal Railway. Of the twenty-three lines established between 1873 and 1890, three remain : two routes from downtown near Union Square to Fisherman's Wharf, and a third route along California Street.
