California Street Cable Railroad

The California Street Cable Railroad (Cal Cable) was a long-serving cable car operator in San Francisco, founded by Leland Stanford. The company's first line opened on California Street in 1878 and is the oldest cable car line still in operation.

The company remained independent until 1951, outlasting all the other commercial streetcar and cable car operators in the city. The city purchased and reopened the lines in 1952; the current cable car system is a hybrid made up of the California Street line, and the Hyde Street section of Cal Cable's O'Farrell, Jones & Hyde line, together with other lines already in municipal ownership.

Some surplus cable cars were sold to Knott's Berry Farm which operated them at its Southern California amusement park from 1955 to 1978. At the end of this period, some were sold back and one (#43) is preserved at the Southern California Railway Museum.
