The San Francisco Cable Car system is a historic mode of transportation in San Francisco, California. Established in 1873, it is the only manually operated cable car system still in use in the world. The cable cars run on tracks and are pulled by underground cables, allowing them to navigate the city's steep hills. The cable car system consists of three lines: the Powell-Hyde, Powell-Mason, and California Street lines. Each line offers scenic views of the city, including landmarks like Fisherman’s Wharf and Chinatown. The cable cars are a popular tourist attraction and a symbol of the city's rich history.
