San Francisco Cable Car System, SFO, U.S.A.

The San Francisco cable car system is the world's last manually operated  cable car system. An icon of  San Francisco, 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. Of the twenty-three lines established between 1873 and 1890,  three remain (one of which combines parts of two earlier lines): two routes from downtown near  Union Square to Fisherman's Wharf, and a third route along California Street. These cable cars are the only mobile National Monument in the world, and are listed on the National Register of Historic Places.

The cable cars are not to be confused with San Francisco's  heritage street cars, which operate on  Market Street  and the Embarcadero.
