Muni Metro


The Muni Metro is a light rail system serving San Francisco, California, United States, operated by the San Francisco Municipal Railway, a division of the San Francisco Municipal Transportation Agency. With an average weekday ridership of 157,700 passengers as of the fourth quarter of 2019, Muni Metro is the United States' second busiest light rail system. Muni Metro operates a fleet of 151 Breda light rail vehicles, which are being supplemented and replaced by Siemens S200 SF LRVs.
Muni Metro is the modern incarnation of the traditional streetcar system that had served San Francisco since the late 19th century. While many streetcar lines in other cities, and even in San Francisco itself, were converted to buses after World War II, five lines survived until the early 1980s, when they were rerouted into the newly built Market Street subway. The system today traverses a number of different types of rights of way, including tunnels, reserved surface trackage with at-grade street crossings, and streetcar sections operating in mixed traffic; surface stops range from high-platform stations to traditional curbside streetcar stops. Recently, the system has undergone expansion, most notably the Third Street Light Rail Project, completed in 2007, which started the first new rail line in San Francisco in over half a century. Other projects, such as the Central Subway, are underway.

History

Beginnings

The first street railroad in San Francisco was the San Francisco Market Street Railroad Company, which was incorporated in 1857 and began operating in 1860, with track along Market Street from California to Mission Dolores. Muni Metro descended from the municipally-owned traditional streetcar system started on December 28, 1912, when the San Francisco Municipal Railway was established. The first streetcar line, the A Geary, ran from Kearny and Market Streets in the Financial District to Fulton Street and 10th Avenue in the Richmond District. The system slowly expanded, opening the Twin Peaks Tunnel in 1917, allowing streetcars to run to the southwestern quadrant of the city. By 1921, the city was operating of electric trolley lines and of cable car lines. The last line to start service before 2007 was the N Judah, which started service after the Sunset Tunnel opened in 1928.
In the 1940s and 1950s, as in many North American cities, public transit in San Francisco was consolidated under the aegis of a single municipal corporation, which then began phasing out much of the streetcar network in favor of buses. However, five heavily used streetcar lines traveled for at least part of their routes through tunnels or otherwise reserved right-of-way, and thus could not be converted to bus lines. As a result, these lines, running PCC streetcars, continued in operation.
Original plans for the BART system drawn up in the 1950s envisioned a double-decked subway tunnel under Market Street in downtown San Francisco; the lower deck would be dedicated to express trains, while the upper would be served by local trains whose routes would spread south and west through the city. However, by 1961 these plans were altered; only a single BART route would travel through the city on the lower deck, while the upper deck would be served by the existing Muni streetcar routes. The new tunnel would be connected to the existing Twin Peaks Tunnel. The new underground stations would feature high platforms, and the older stations would be retrofitted with the same, which meant that the PCCs could not be used in them. Hence, a fleet of new light rail vehicles was ordered from Boeing-Vertol, but were not delivered until 1979–80, even though the tunnel was completed in 1978. The K and M lines were extended to Balboa Park during this time, providing further connections to BART.
On February 18, 1980, the Muni Metro was officially inaugurated, with weekday N line service in the subway. The Metro service was implemented in phases, and the subway was served only on weekdays until 1982. The K Ingleside line began using the Metro subway on weekdays on June 11, 1980, the L Taraval and M Ocean View lines on December 17, 1980, and lastly the J Church line on June 17, 1981. Meanwhile, weekend service on all five lines continued to use PCC cars operating on the surface of Market Street through to the Transbay Terminal, and the Muni Metro was closed on weekends. At the end of the service day September 19, 1982, streetcar operations on the surface of Market Street were discontinued entirely, the remaining PCC cars taken out of service, and weekend service on the five light rail lines was temporarily converted to buses. Finally, on November 20, 1982, the Muni Metro subway began operating seven days a week.
At the time, there were no firm plans to revive any service on the surface of Market Street or return PCCs to regular running. However, tracks were rehabilitated for the 1983 Historic Trolley Festival, and the inauguration of the F Line, served by heritage streetcars, followed in 1995.
in 1993
By the late 1980s, Muni scheduled 20 trains per hour through the Market Street subway at peak periods, with all trains using the crossover west of Embarcadero station to reverse direction.. To allow for high frequencies on the surface branches, eastbound trains were combined at West Portal and Duboce Portal, and westbound trains split at those locations. Two-car N Judah trains and one-car J Church trains combined at the Duboce Portal, while two-car L Taraval trains alternately combined with two-car M Ocean View and K Ingleside trains at West Portal to form four-car trains. However, this provided suboptimal service; many inbound trains did not arrive at the portals in time to combine into longer trains.

Muni meltdown

In the mid- to late-1990s, San Francisco grew more prosperous and its population expanded with the advent of the dot-com boom, and the Metro system began to feel the strain of increased commuter demand. Muni criticism had been something of a feature of life in San Francisco, and not without reason. The Boeing trains were sub-par and grew crowded quickly. And the difficulty in running a hybrid streetcar and light rail system, with five lines merging into one, led to scheduling problems on the main trunk lines with long waits between arrivals and commuter-packed trains sometimes sitting motionless in tunnels for extended periods of time.
Muni did take steps to address these problems. Newer, larger Breda cars were ordered, an extension of the system towards South Beach — where many of the new dot-coms were headquartered — was built, and the underground section was switched to Automatic Train Operation. The Breda cars, however, came in noisy, overweight, oversized, under-braked, and over-budget. In fact, the new trains were so heavy that some homeowners, claiming that the exceptional weight of the Breda cars damaged their foundations, sued the city of San Francisco. The Breda cars are longer and wider than the previous Boeing cars, necessitating the modification of subway stations and maintenance yards, as well as the rear view mirrors on the trains themselves. Furthermore, the Breda cars do not run in three car trains, like the Boeing cars used to, as doing so had, in some instances, physically damaged the overhead power wires. The Breda trains were so noisy that San Francisco budgeted over $15 million to quiet them down, while estimates range up to $1 million per car to remedy the excessive noise. To this day, the Breda cars are noisier than the PCC or Boeing cars. In 1998, NTSB inspectors mandated a lower speed limit of, down from, because the brakes were problematic.
The ATC system was plagued by numerous glitches when first implemented, initially causing significantly more harm than good. Common occurrences included sending trains down the wrong tracks, and, more often, inappropriately applying emergency braking. Eventually the result was a spectacular service crisis, widely referred to as the "Muni meltdown", in the summer of 1998. During this period, two reporters for the San Francisco Chronicle—one riding in the Muni Metro tunnel and one on foot on the surface—held a race through downtown, with the walking reporter emerging the winner.
After initial problems with the ATC were fixed, substantial upgrades to the entire Muni transit systems have gone a long way towards resolving persistent crowding and scheduling issues. Nonetheless, Muni remains one of the slowest urban transport systems in the United States.

Recent expansion

In 1980, the M Ocean View was extended from Broad Street and Plymouth Avenue to its current terminus at Balboa Park. In 1991, the J Church was extended from Church and 30th Streets to its current terminus at Balboa Park. In 1998, the N Judah was extended from Embarcadero Station to the planned site of the new Pacific Bell Park and Caltrain Depot, after that extension was briefly served between January and August of that year by the temporary E Embarcadero light rail shuttle.
In 2007, the T Third Street, running south from Caltrain Depot along Third Street to the southern edge of the city, opened as part of the Third Street Light Rail Project. Limited weekend T line service began on January 13, 2007, while full service began on April 7, 2007. The line initially ran from the southern terminus at Bayshore Boulevard and Sunnydale Street to Castro Street Station in the north. The line ran into initial problems with breakdowns, bottlenecks, and power failures, creating massive delays. Service changes to address complaints with the introduction of the T Third Street were implemented on June 30, 2007, when the K and T trains were interlined, or effectively merged into one single line with route designations changing at the entrances into the subway.
On March 30, 2020, Muni Metro service was replaced with buses due to the COVID-19 pandemic. Rail service is expected to return in August 2020, with the routes reconfigured to improve reliability in the subway: K Ingleside and L Taraval service will be interlined, running between Wawona and 46th Avenue station and Balboa Park station; no K or L service will enter the subway. J Church service will run only on the surface between Balboa Park station and Church and Duboce station. M Ocean View and T Third Street service will be interlined, running between Sunnydale station and Balboa Park station; it will run in the subway along with normal N Judah service and increased S Shuttle service.

Future expansion

Several expansion projects are underway or under study. Federal funding has been secured for, and construction has begun on, the Central Subway, a combined surface and subway extension of the T Third Line, running from Caltrain Depot to Chinatown, with stops at Moscone Center and Union Square, and with the potential for a future expansion to North Beach and Fisherman's Wharf. Muni estimates that the Central Subway section of the T Third Line will carry roughly 35,100 riders per day by 2030. The Central Subway is projected to be complete and ready for revenue service in late 2021 at a projected cost of $1.578 billion. Once the Central Subway is complete, it may also continue as an above-ground light rail line through North Beach, and into the Marina district, with the possibility of eventually terminating in the Presidio.
A project to grant the M Ocean View its own separated right-of-way called the Muni Subway Expansion Project, building off of a 2014 SFCTA study, is undergoing preliminary engineering studies by the SFMTA as of 2018. The project would extend the Muni subway service in a tunnel under 19th Avenue, providing grade-separated service from Embarcadero station to a proposed Park Merced station.
The 20-year Capital Plan for the SFMTA also lists both a Geary Light Rail project and a Geneva Avenue Light Rail project.

Infrastructure

The Muni Metro system consists of of standard gauge track, seven light rail lines, three tunnels, nine subway stations, 24 surface stations, and 87 surface stops.

The backbone of the system is formed by two interconnected subway tunnels, the older Twin Peaks Tunnel and the newer Market Street subway, both controlled by automatic train operation systems to run trains with the operators closing the door to allow the train to pull out of a station. This ATO system was upgraded in 2015 to replace outdated software and relays. The tunnels, in total length, run from West Portal Station in the southwestern part of the city to Embarcadero Station in the heart of the Financial District. Three lines—the K Ingleside, the L Taraval, and the M Ocean View—feed into the tunnel at West Portal, while two lines, the J Church and N Judah, enter at a portal near Church Street and Duboce Avenue in the Duboce Triangle neighborhood. Two lines, the N Judah and T Third Street, enter and exit the tunnel at Embarcadero. An additional tunnel, the Sunset Tunnel, is located near the Duboce portal and is served by the N.
The interconnected tunnels contain nine subway stations. Three stations—West Portal, Forest Hill and the now-defunct Eureka Valley—were opened in 1918 as part of the Twin Peaks Tunnel, while the other seven—Castro Street, Church Street, Van Ness, Civic Center, Powell Street, Montgomery Street and Embarcadero—were opened in 1980 as part of the Market Street subway. Four stations, Civic Center, Powell Street, Montgomery Street, and Embarcadero, are shared with Bay Area Rapid Transit, with Muni Metro on the upper level and BART on the lower one.
Above ground, there are twenty-four surface platform stations. Two stations, Stonestown and San Francisco State University are located at the southwestern part of the city, while the rest are located on the eastern side of the city, where the system underwent recent expansion as part of the Embarcadero extension and the Third Street Light Rail Project. However, many of the stops on the system are surface stops consisting of anything from a traffic island to a yellow-banded "Car Stop" sign painted on a utility pole.
All subway and surface stations are handicap-accessible. In addition, several surface street stops are also handicap-accessible, often consisting of a ramp leading up to a small platform for boarding.
In Muni Metro terminology, an inbound train is one that heads from the western neighborhoods and West Portal towards Embarcadero, while an outbound train travels in the opposite direction out of downtown towards the west. Even the T Third Street Line is consistent with this terminology, with an inbound train going from West Portal through Embarcadero to Sunnydale, and an outbound train running out of the southeastern neighborhoods into downtown.
Muni Metro has two rail yards for storage and maintenance:

Notes

1979–2002: Boeing Vertol USSLRV

Muni Metro first operated Boeing Vertol-made US Standard Light Rail Vehicles, which were built for Muni Metro and Boston's MBTA. Boeing had no experience in making LRVs, and has not made another since. The first cars of the initial 100-car order arrived in San Francisco in 1978; Boston had been running the cars since 1976 and by 1978, MBTA was already returning 35 cars for manufacturing defects. After receipt of the first cars, MBTA forced Boeing to make 70 to 80 modifications on each car. Boeing ended up paying in damages to Boston. The purchase price for each car was.
The federal government offered to provide 80% of the funds for design and production of the USSLRV in exchange for a commitment to keep the cars in service for at least 25 years, but the cars, as-delivered, were prone to jammed doors, defective brakes and motors, leaky roofs, mechanical breakdowns, and were involved in several accidents. Muni Metro added 30 more cars to the fleet; these 30 had been rejected by MBTA after suffering numerous breakdowns.
In 1982, the Boeing cars averaged only between breakdowns; by 1988 this had improved to between breakdowns. In 1998, Rudy Nothenberg, president of the Public Transportation Commission, said the Boeing cars were "impossible to maintain and have many, many design flaws;" that same year, Muni was only able to supply 66–72 working cars for rush-hour service instead of the required 99 cars, resulting in system delays. Despite the shortcomings of the USSLRV design, these cars constituted the entire light rail fleet until 1996, when new Breda-manufactured cars were put into service, replacing Boeing cars as they were accepted for service. By 1998, the 136-car Muni Metro fleet consisted of 57 Boeing Vertol cars and 79 Breda cars.
Two Boeing cars were preserved for potential donation to the San Francisco Railway Museum, but have since been scrapped; five were sold to the Greater Manchester Passenger Transport Authority for the modest price of to each; one was acquired by the Oregon Electric Railway Historical Society in 2001, but the Society declined to take any more Boeing cars after experiencing several breakdowns. Boeing car no. 1258 has been on exhibit at the Western Railway Museum near Suisun City since its acquisition in 2002.

1996–present: Breda LRV-2/-3

The first of four prototypes of the new Breda cars was delivered in January 1995. After delivery of additional cars and training of operators, the cars began to enter service on December 10, 1996. They were the most expensive street railway vehicles built to-date, at a cost of each, and they were assembled at Pier 80. After suffering initial breakdowns and despite facing complaints of noise and vibrations, the Bredas gradually replaced the Boeings, with the last Boeing car being retired in 2002. Residents along streetcar lines complained the new Breda cars would screech during acceleration and deceleration and their weight, heavier than the Boeing cars, was blamed for vibration issues. At one point in 1998, 12 Breda cars were unavailable for service due to door problems. Faulty couplers on the Breda cars have been blamed for reduced train capacity, as multiple cars are not able to be coupled together as intended.
Muni originally ordered 35 cars from Breda in 1991, and exercised options to add another 116 cars throughout the 1990s, including an option to purchase another 15 cars in 1999. The fleet had 151 LRVs in 2014, all made by Breda. The double-ended cars are long, wide, high, have graffiti-resistant windows, and contain an air-conditioning system to maintain a temperature of inside the car. The Breda cars feature four doors per car, versus three for the Boeing. The initial batch of 136 Breda cars were ordered on contracts exceeding, for an average per-car cost of ; the option of 15 additional cars was exercised on a contract worth, making the last batch of 15 cars each.

2017–present: Siemens S200 SF

With the construction of the Central Subway and ongoing system capacity increase, there are plans to add 24 more cars with Siemens, Kawasaki, and CAF having been prequalified to bid; Breda was disqualified based on a ranking of potential bidders. The contract was awarded to Siemens for the purchase of a total of 260 cars, and Muni is expected to choose from three initial designs in the new S200 class. The 260 cars would be delivered in three phases: the initial batch of 24 would be used on the new Central Subway, the next batch of 151 would replace the existing fleet starting in 2021 as they reached their 25-year life expectancy, and another 85 would be added, funding permitting, to accommodate projected ridership growth through 2040. Muni partially exercised their option and added 40 cars from the third phase by 2015. By November 2019, the Siemens order totaled 219 vehicles: 151 cars to replace the Breda LRV2/3 fleet, and 68 cars to accommodate expansion plans. Delivery of the "future fleet" of 68 expansion cars was completed in October 2019.
Upon awarding the contract, Muni officials cited several lessons learned from the prior Breda contract, including not buying enough cars, dictating too much of the design, lax reliability requirements, and a failure to account for maintenance costs. The contract for 175 cars was signed by Mayor Ed Lee in September 2014, making the cost of each car approximately. They are expected to have the same coupling device as the Breda cars, however, the new Siemens trains can couple up to five cars at a time.

Design

Siemens has named the new Muni cars the S200 SF, while the SFMTA refers to them as the LRV4. They operate at speeds of up to. The S200 SF is long, wide, high, and weighs, making it comparable in size and weight to the existing Breda cars. The expected maximum capacity is 203 passengers per car.

Reliability

The new S200 SF vehicles are projected to be able to run between maintenance intervals. Initially, the new cars had a mean distance between failures of shortly after being delivered; by August 2019, the MDBF had improved to. In comparison, the Breda-based fleet was only able to manage between failures in 2011.

Service history

Siemens publicly unveiled a full-size mockup of the S200 SF in San Francisco on June 16, 2015. The first 64 S200 SF cars will be used to expand the Muni fleet to 215 cars; once the fleet reaches 215 cars, Breda cars will be retired as new Siemens cars are accepted. On July 2, 2015, Muni was awarded a grant of $41 million from the California Transportation Agency to eventually pay for 40 of the 64 additional Siemens light rail vehicles. The first car was delivered from the Siemens plant in Sacramento to San Francisco on January 13, 2017; it is expected that deliveries will continue through 2028. In early November 2017, a test car passed a CPUC regulatory inspection with only minor correctable issues and received permission to begin revenue service as early as November 15. The five additional test cars may be certified by December.
The first S200, #2006, went into service on November 17, 2017, following a ribbon-cutting ceremony at Duboce and Church. Muni also announced that instead of bringing 24 new cars in service in 2018, 68 would be commissioned because of speedy production. Two-car LRV4 trains entered service in June 2018. Three-car trains have been tested, and SFMTA is planning to use three-car trains for special events and peak hour service as early as the second quarter of 2018.

Fares and operations

Muni Metro runs from approximately 5 am to 1 am weekdays, with later start times of 7 am on Saturday and 8 am on Sunday. Owl service, or late-night service, is provided along much of the L and N lines by buses that bear the same route designation.
The cash fare for Muni Metro, like Muni buses, effective January 1, 2020, is $3 for adults and $1.50 for youth ages 5–17, seniors, and the disabled. Clipper and MuniMobile fares are lower than cash fares. Their fares are $2.50 for adults and $1.25 for youth ages 5–17, seniors, and the disabled.
Muni currently operates a program that provides low- and moderate-income seniors residing in San Francisco free access to all Muni transit services, including Muni's cable cars. Free Muni is open to all San Francisco senior Clipper card holders, ages 65 and over, with a gross annual family income at or below 100 percent of the Bay Area Median Income level. Enrollment is not automatic. To participate in the program, a qualified senior must have or obtain a Clipper card and submit an application either online or by mail.
Like Muni buses, the Muni Metro operates on a proof-of-payment system; on paying a fare, the passenger will receive a ticket good for travel on any bus, historic streetcar, or Metro vehicle for 120 minutes. Payment methods depend on boarding location. On surface street sections in the south and west of the city, passengers must board at the front of the train and pay their fare to the train operator to receive their ticket; those who already have a ticket, or who have a daily, weekly, or monthly pass, can board at any door of the Metro streetcar. Subway stations have controlled entries via faregates, and passengers usually purchase or show Muni staff a ticket in order to enter the platform area. Faregates closest to an unmanned Muni staff booth open automatically if a passenger has a valid pass or transfer that cannot be scanned. Muni's fare inspectors may board trains at any time to check for proof of payment from passengers.
All cars are also equipped with Clipper card readers near each entrance, which riders may use to tag their cards to pay their fare. The cards themselves are then used as proof of payment; fare inspectors carry handheld card readers that can verify that payment was made. In subway stations, riders instead tag their cards on the faregates to gain access to the platforms.
