(Line 61 or C) line runs east and west on California Street from a terminal at California and Market Streets, close to the famed Embarcadero to Van Ness Avenue. The California Street cable cars use double-ended cars with "grip" levers at either end of the longer cars which are operated in each direction without the cars being turned at the ends of the line, where the double tracks converge into a single "stub-end" track. The line once ran a much longer distance from Presidio Avenue to Market Street but service west of Van Ness Avenue was discontinued in 1954. Calls to restore the route to its original length are heard from time to time but nothing serious towards this end has been proposed. This route runs only on California Street, running at first uphill to the summit of Nob Hill, then more gently downhill to a terminus at Van Ness Avenue. This line is used to a greater extent by commuters, with the majority of passengers on weekdays being commuters. There is also a set of non-revenue tracks from the California Street line along Hyde Street to join the Powell–Hyde line at Hyde and Washington. This connection exists to enable California Street cars to reach the car barn. A small signal tower controls the crossing of the lines at the intersection of California Street and Powell Street. It has been rebuilt in 1907, 1937, 1967, and 2020–2021. The system generally starts operating at 5:30 am each day and shuts down at 1:30 am. The cable car system connects at both its terminals on Market Street with the F Market heritage streetcar line. The Taylor and Bay terminal, and the Hyde and Beach terminal, are both short walks from the F Market line. The system connects with other Muni lines and BART at the Powell & Market and California & Drumm terminals. Fares As of January 1, 2020, riding a cable car costs $8 for a single ride, except for seniors riding before 7 am or after 9 pm when the fare is $4.
