Landmark
The San Francisco cable car system is the world's last manually operated cable car system and an icon of the city of San Francisco. The system forms part of the intermodal urban transport network operated by the San Francisco Municipal Railway. Of the 23 cable car lines established between 1873 and 1890, only three remain : 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, the vast majority of the millions of passengers who use the system every year are tourists, and as a result, the wait to get on can often reach two hours or more. San Francisco's cable cars are listed on the National Register of Historic Places and are designated as a National Historic Landmark. — Wikipedia
