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, which also includes the separate E Embarcadero and F Market & Wharves heritage streetcar lines, and the Muni Metro modern light rail system. Of the 23 cable car lines established between 1873 and 1890, only 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. 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. They are among the most significant tourist attractions in the city, along with Alcatraz Island, the Golden Gate Bridge, and Fisherman's Wharf. San Francisco's cable cars are listed on the National Register of Historic Places and are designated as a National Historic Landmark.

History

Beginnings

The Clay Street Hill Railroad in its early years

In 1869, Andrew Smith Hallidie had the idea for a cable car system in San Francisco, reportedly after witnessing an accident in which a streetcar drawn by horses over wet cobblestones slid backwards, killing the horses.[7][8] Hallidie solicited financial support in 1871 and 1872, and his primary backers were Henry L. Davis, Joseph Britton, and James Moffit.[9]: 311 

The first successful cable-operated street running train was the Clay Street Hill Railroad, which had its inaugural run on August 2, 1873.[8] The promoter of the line was Hallidie, and the engineer was William Eppelsheimer;[8] both Hallidie and Eppelsheimer obtained several patents for their work on the Clay Street line.[9]: 312 [a][b] The line involved the use of grip cars, which carried the grip that engaged with the cable, towing trailer cars; the design was the first to use grips. The term "grip" became synonymous with the operator.

The line started regular service on September 1, 1873, and its success led it to become the template for other cable car transit systems.[8] It was a financial success, and Hallidie's patents were enforced on other cable car promoters, making him wealthy.

Accounts differ as to the precise degree of Hallidie's involvement in the inception of the line, and to the exact date on which it first ran. According to the franchise granted by the city, operations were required to begin by August 1, 1873.[8] A retrospective published in 1895 stated that a single car was run over the line at 4 AM on the morning of August 1 with few witnesses to ensure the franchise would not expire.[9]: 312  Eppelsheimer would later bring a suit against Hallidie and the Clay Street Hill RR in June 1877 over patents, but dismissed it voluntarily the following March.[10]: 622

The next cable car line to open was the Sutter Street Railway, which converted from horse operation in January 1877.[8] This line introduced the side grip, and lever operation, both designed by Henry Casebolt and his assistant Asa Hovey, and patented by Casebolt.[9]: 312, 315  This idea came about because Casebolt did not want to pay Hallidie royalties of $50,000 a year for the use of his patent. The side grip allowed cable cars to cross at intersections.

In 1878, Leland Stanford opened his California Street Cable Railroad (Cal Cable).[8] This company's first line was on California Street, and is the oldest cable car line still in operation. In 1880, the Geary Street, Park & Ocean Railway began operation.[8] The Presidio and Ferries Railway followed two years later, and was the first cable company to include curves on its routes. The curves were "let-go" curves, in which the car drops the cable and coasts around the curve on its own momentum.

In 1883, the Market Street Cable Railway opened its first line.[8] This company was controlled by the Southern Pacific Railroad and would grow to become San Francisco's largest cable car operator. At its peak, it operated five lines, all of which converged on Market Street to a common terminus at the Ferry Building. During rush hours, cars left that terminus every 15 seconds.[12]

In 1888, the Ferries and Cliff House Railway opened its initial two-line system.[8] The Powell–Mason line is still operated on the same route today; their other route was the Powell–Washington–Jackson line, stretches of which are used by today's Powell–Hyde line. The Ferries & Cliff House Railway was also responsible for the building of a car barn and powerhouse at Washington and Mason, and this site is still in use today. In the same year, it also purchased the original Clay Street Hill Railway, which it incorporated into a new Sacramento–Clay line in 1892.[8]

In 1889, the Omnibus Railroad and Cable Company became the last new cable car operator in San Francisco.[8] The following year the California Street Cable Railroad opened two new lines, these being the last entirely new cable car lines built in the city. One of them was the O'Farrell–Jones–Hyde line, the Hyde section of which still remains in operation as part of the current Powell–Hyde line.

In all, twenty-three lines were established between 1873 and 1890.[13]

Eight original cable car companies[13]
Name Lines Gauge Grip Start End Notes
Clay Street Hill Railroad 1 3 ft 6 in (1.07 m) bottom Sep 1873 Sep 1888 Original route along Clay from Kearny to Leavenworth; extended west to Van Ness in 1877. Sold to Ferries & Cliff House Railway; route incorporated into Clay-Sacramento line.[14]
Sutter Street Railway 2 5 ft 0 in (1.52 m) side Jan 1877 Mar 1902 Initial route along Sutter from Market to Larkin, later extended to Central (Presidio); second (crosstown) line added in 1878 along Larkin from Bush to Hayes. Crosstown line eventually extended south along 9th to Brannan and north to Pacific, then west to Fillmore. Consolidated into United Railroads of San Francisco.[15]

Second line added in 1891 (O'Farrell, Jones & Hyde) with small feeder line from Market, Jones & McAllister. Purchased by San Francisco in 1951.[16]
Geary Street, Park & Ocean Railway 1 5 ft 0 in (1.52 m) bottom Feb 16, 1880 May 5, 1912 Initial line ran along Geary from Market to Presidio, where a steam engine was added for service to western terminus at 5th and Fulton. Converted to standard gauge and side grip in 1892 and cable drawn line extended to 1st; franchise expired in 1912 and the line was taken over for Muni.[17]
Presidio & Ferries Railway 1 5 ft 0 in (1.52 m) bottom Jan 1882 Apr 1906 Ran along Columbus from Montgomery to Union, then west along Steiner; continued to Presidio via steam drawn line. Converted to electric following April 1906 earthquake; sold to San Francisco in Dec 1913 and became part of Muni.[18]
Market Street Cable Railway 5 4 ft 8+12 in (1.435 m) side Aug 1883 Oct 1893 Main line originated from Ferry Building and ran along Market. Branch lines opened along Valencia south to 29th (1883); and three branches west to Golden Gate Park along McAllister, Haight, and Hayes (1886). Market line extended to Castro, then south to 26th in 1887. Reorganized in 1893 as Market Street Railway and most lines converted to electric.[19]
Ferries & Cliff House Railway 4 3 ft 6 in (1.07 m) bottom Mar 1888 Powell line ran from Powell and Market past Union Square to Bay & Taylor; second line ran along Washington and Jackson to Central & Sacramento, then continued using steam power to Cliff House. Reorganized in 1893 as Market Street Railway.[20]
Omnibus Railroad & Cable Company 5 3 ft 6 in (1.07 m) bottom Aug 1889 Reorganized in 1893 as Market Street Railway.[21]

Evolution of motive power

Originally, the cables were powered by stationary steam engines.[22] For the initial three cables, the Ferries & Cliff House Railway constructed a three-story structure to house two 450-horsepower coal-burning steam engines.[22] The building was complete with a 185-foot-tall smokestack to vent away the heavy black smoke created by the Welsh anthracite coal that the company burned.[22] Expansion of service required two additional 500-horsepower coal-fired steam engines in 1890, and the number and type of engines continued to vary over time.[22] Coal consumption in 1893 was about 10 tons per day.[22] The system was converted to oil in 1901, and the lessened amount of smoke allowed the smokestack to be shortened to 60’; this shortened smokestack still exists at Washington-Mason today.[22]

Electric energy was introduced in 1912, when a 600-horsepower General Electric motor came on-line.[22] By 1926, all steam operation of the cable ended when a second complete electrical drive was installed, a 750-horsepower General Electric product.[22] With reduction in the number of cable car lines, the single 750-horsepower electric motor took over the job of running all of the lines.[23][24] The problem with that configuration was that if one cable car on one line broke down, all lines had to be stopped.[24] After the 1984 reconstruction, each of the four cables for the three lines (California, Hyde, Mason and Powell) is separately powered by its own 510-hp electric motor.[8]

Decline

The first electric streetcars in San Francisco began operation in 1892 under the auspices of the San Francisco and San Mateo Electric Railway.[8]

By the beginning of 1906 many of San Francisco's remaining cable cars were under the control of the United Railroads of San Francisco (URR), although Cal Cable and the Geary Street Company remained independent. URR was pressing to convert many of its cable lines to overhead electric traction, but this was met with resistance from opponents who objected to what they saw as ugly overhead lines on the major thoroughfares of the city center.[8]

Those objections disappeared after the 1906 San Francisco earthquake. The quake and resulting fire destroyed the power houses and car barns of both the Cal Cable and the URR's Powell Street lines, together with the 117 cable cars stored within them. The subsequent race to rebuild the city allowed the URR to replace most of its cable car lines with electric streetcar lines. By 1912, only eight cable car lines remained, all with steep gradients impassable to electric streetcars.[8] In the 1920s and 1930s, these remaining lines came under pressure from the much improved buses of the era, which could now climb steeper hills than the electric streetcar. By 1944, five of those cable car lines had survived: the two Powell Street lines – by then under municipal ownership, as part of Muni – and the three lines owned by the still-independent Cal Cable.[8]

Fight to remain open

In 1947, Mayor Roger Lapham proposed the closure of the two municipally owned lines. In response, a joint meeting of 27 women's civic groups, led by Friedel Klussmann, formed the Citizens' Committee to Save the Cable Cars. In a famous battle of wills, the citizens' committee eventually forced a referendum on an amendment to the city charter, compelling the city to continue operating the Powell Street lines. This passed overwhelmingly, by 166,989 votes to 51,457. Klussman led another campaign in 1948 to have the city acquire Cal Cable, but the referendum fell short of the required 23 majority, with 58% in favor of acquisition; a second referendum in 1949, requiring a simple majority, passed and the city began negotiations with Cal Cable.[25]

In August 1951, the three Cal Cable lines were shut down when the company was unable to afford insurance. The city purchased and reopened the lines in January 1952, but another referendum that would have funded maintenance for the California Street tracks and the powerhouse and car barn at Hyde and California failed in November 1953. The amendment to the city charter did not protect the newly acquired Cal Cable lines, and the city proceeded with plans to replace them with buses; in addition, businesses in Union Square and downtown began advancing plans to convert O'Farrell to automobile traffic, which would remove service through the Tenderloin district via the inner section of the O'Farrell Jones & Hyde line.[25] The result was a compromise that formed the current system: a protected system made up of the California Street line from Cal Cable, the Powell–Mason line already in municipal ownership, and a third hybrid line formed by grafting the Hyde Street section of Cal Cable's O'Farrell-Jones-Hyde line onto a truncated Powell–Washington–Jackson line, now known as the Powell–Hyde line.

This solution required some rebuilding to convert the Hyde Street trackage and terminus to operation by the single-ended cars of the Powell line, and also to allow the whole system to be operated from a single car barn and power house. Much of the infrastructure remained unchanged from the time of the earthquake.

Rebuild

By 1979, the cable car system had become unsafe; it needed to be closed for seven months for urgently needed repairs. A subsequent engineering evaluation concluded that it needed comprehensive rebuilding at a cost of $60 million.[26] Mayor Dianne Feinstein, who took charge of the effort, helped win federal funding for the bulk of the rebuilding job. In 1982 the cable car system was closed again for a complete rebuild. This involved the complete replacement of 69 city blocks' worth of tracks and cable channels, the complete rebuilding of the car barn and powerhouse within the original outer brick walls, new propulsion equipment, and the repair or rebuild of 37 cable cars.[26] The system reopened on June 21, 1984, in time to benefit from the publicity that accompanied San Francisco's hosting of that year's Democratic National Convention.[26]

Recent history

Since 1984, Muni has continued to upgrade the system. Work has included rebuilding of another historical car, the building of nine brand new replacement cars, the building of a new terminal and turntable at the Hyde and Beach terminus, and a new turntable at the Powell and Market terminus.

Between 2017 and 2019, the system received a second, but less extensive rebuild. Over the two year project, Muni rehabilitate the gearboxes that power the cable car system that had been in service since the last rebuild in 1984.[27]

The system was shut down in March 2020 to protect operators during the COVID-19 pandemic, as cable cars do not offer a compartment separating them from passengers (unlike Muni buses, which kept running).[28] Limited service on all three lines resumed on August 2, 2021.[29] Full revenue service began on September 4.[30] On September 9, a valve failure caused the fire suppression system in the carbarn to activate, shutting down electric power to the powerhouse.[31] Service resumed on September 18.[32]

Controversies

The cable cars are an iconic part of San Francisco and are protected National Historic Landmarks, but they are not without their critics. Most complaints center around the high cost of operating a system that mostly serves tourists, and the large number of accidents involving the cable cars.

The cable car lines serve around seven million passengers per year, but the vast majority are tourists, rather than commuters.[33] The area where the cable cars operate is well-served by a large number of buses and trolleybuses that often give residents better options for their trips. Also, during busy times, the wait to board a cable car can often reach two hours or more.[33]

While Muni does allow monthly passholders to ride the cable cars at no additional charge, single ride fares are more than triple the fares charged on other Muni routes. The high fares led the San Francisco Chronicle to describe the cable cars in 2017 as a "cash cow" for Muni, yielding a yearly revenue of around $30 million.[34] Still, according to Mission Local, the cable car system had a $46 million operating deficit in 2019.[35] In 2006, then-Mayor Gavin Newsom reported that he had observed several conductors pocketing cash fares from riders without receipt.[34] The following year, the San Francisco auditor's office reported that the city was not receiving the expected revenue from cable cars, with an estimated 40% of cable car riders riding for free. Muni's management disputed this figure and pointed out that safe operation, rather than revenue collection, is the primary duty of conductors.[36] In 2017, after an audit showing that some conductors were "consistently turn[ing] in low amounts of cash", as well as a sting operation, one conductor was arrested on charges of felony embezzlement.[34]

Among U.S. mass transportation systems the cable cars have the most accidents per year and per vehicle mile, with 126 accidents and 151 injuries reported in the 10 years ending 2013.[33] In the three years ending 2013 the city paid some $8 million to settle four dozen cable car accident claims.[33]

Operation

Cables and grip

The cable cars are pulled by a cable running below the street, held by a grip that extends from the car through a slit in the street surface, between the rails.[12] Each cable is 1.25 inches (3.2 cm) in diameter, running at a constant speed of 9.5 miles per hour (15.3 km/h), and driven by a 510 horsepower (380 kW) electric motor located in the central power house (see below), via a set of self-adjusting sheaves.[12] Each cable has six steel strands, with each strand containing 19 wires, wrapped around a sisal rope core[12] (to allow easier gripping). The cable is coated with a synthetic lubricant to reduce wear and friction. Historically, pine tar was used to lubricate the cable.[12] To start and stop the movement of the car, the grip operator (see below) closes and opens the grip around the cable (similar to the clutch of a conventional car).[12] The grip's jaws exert a pressure of up to 30,000 pounds per square inch (210,000 kPa) on the cable.[12] Due to wear and tear, a grip's dies have to be replaced after three days of usage.[37]

There are four separate cables: one 16,000-foot (4,900 m) length and one 10,300-foot (3,100 m) length for the Hyde and Mason segments, a 9,300-foot (2,800 m) length for their common Powell section, and one 21,000-foot (6,400 m) length for the California Street line.[12]

Brakes

Apart from the cable itself (which limits the speeds of cars when going downhill), the cable cars use three separate braking systems:[38]

Electrical system

Over the years, the cable cars have been retrofitted with several electrical components, including headlights, interior lighting, a GPS tracking system and cameras. However, unlike most modern trains, the cable cars have no method to generate power on board and instead must use large batteries that are recharged in the car barn. In 2018, the incandescent bulbs used for the headlights and interior lighting were replaced with LED bulbs which increased visibility for operators and had a lower drain on the batteries.[40]

Network

The current cable car network consists of three routes:

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.[46]

The system generally starts operating at 5:30am each day and shuts down at 1:30am.[37]

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 7am or after 9pm when the fare is $4. Cable car rides are included in monthly Muni passes, as well as 1-day, 3-day, 7-day passes, and the CityPASS program. Passes loaded on a Clipper card can be read by the conductor with a mobile device. Transfers or fare receipts are not accepted.[47] In the 1960s, the fare for a single ride was 15 cents.[34]

Cars

There are 27 cars in rotation when the system is operating.[37] They come in two kinds:

There are 28 single-ended cars available for operation on the Powell lines and 12 double-ended cars on the California Street line.[50]

Both types of car ride on a pair of four-wheel trucks, to fit the track's 3 ft 6 in (1,067 mm) narrow gauge. The term California Street car, as in a car running on the California Street line, should not be confused with the term California Car. The latter term applies to all the cable cars currently operating in San Francisco, and is a historical term distinguishing this style of car from an earlier style where the open grip section and the enclosed section were separate four-wheel cars (known as the grip car and trailer).

The cable cars are occasionally replaced with new or restored cars, with the old cars being moved to storage for later restoration. There are two historic cable cars in storage in the cable car museum: car numbers 19 and 42, which were used on the Sacramento-Clay and O'Farrell, Jones and Hyde Street lines, respectively.

Car barn, power house, and museum

The cable-car barn is located between Washington and Jackson Streets just uphill of where Mason Street crosses them. Cars reverse into the barn off Jackson Street and run out into Washington Street, coasting downhill for both moves. To ensure that single-ended cars leave facing in the correct direction, the car barn contains a fourth turntable. Cars are moved around the car barn with the assistance of a rubber-tired tractor.

As of 2018, the cable-car barn was staffed with 17 mechanics, six custodians, three carpenters, two painters, two supervisors and one superintendent.[37]

The car barn is situated directly west of the power house and the Cable Car Museum. The museum's entrance is at Washington and Mason. It contains several examples of old cable cars, together with smaller exhibits and a shop. Two galleries allow the visitor to overlook the main power house, and also to descend below the junction of Washington and Mason Streets and see the large cavern where the cables are routed out to the street via huge sheaves.

Crew

The car is driven by the grip, whose job requires strength, coordination, and balance. The grip must smoothly grip and release the cable, know the points at which the grip must be released to coast over intersecting lines or places where the cable does not follow the tracks, and maintain clearance from other traffic. The conductor collects fares, manages crowding, and controls the rear-wheel brakes on some hills.

On the second or third Thursday each July, a cable car bell-ringing contest is held in Union Square between cable car crews, following a preliminary round held during the second to last or the last week of June. The preliminary round determines which contestants go on to the finals in Union Square, by a process of points awarded by a panel of judges.[51][52][53]
