Save Muni has long called for a management audit of the San Francisco Municipal Transportation Agency. To that request we now must add: Review the agency’s structure. Well-reported problems with new train cars, operator shortages and maintenance problems last month have only highlighted the agency’s shortcomings.

The SFMTA was created over a decade ago to bring all the city’s transportation under one agency. As envisioned, professionals would work together to develop integrated policies and programs that served the public better than separate taxi, streets and transit departments. It simply was assumed that keeping politics out of transportation, by insulating the SFMTA from the San Francisco Board of Supervisors, would assure better decisions.

Save Muni Calls Out Defects in the new LRVs

Date: March 26, 2019

Ed Reiskin,
Director of Transportation
San Francisco MTA

Save Muni recognizes that Muni needs new Light Rail Vehicles (LRV’s) to replace the aging fleet of Breda cars. However, the first cohort of the new Siemens cars, which are now in service, are a huge disappointment and clearly need design changes to better serve San Francisco transit riders.

The SFMTA seems to have focused on cramming as many riders as possible into the cars with uncomfortable seating and poorly designed multipurpose areas. More importantly it appears that no attention was paid to the ability to quickly safely, and smoothly couple cars to achieve the 3-and-4 car trains that the Market Street Subway was designed for.

Save Muni members have identified some other problems with the new cars. 1) jerky acceleration which leads to the danger of rider injuries:.2) inability to provide a level step onto subway platforms 3) flawed interior design that leads to sliding on the bench seats: 4) inadequate numbe kr of stanchions and straps 5) poor door configuration which hinders boarding, especially for disabled riders: 6) narrower pantograph width which will lead to both vehicle and overhead wire damage.


SFMTA Ignores Muni Metro Crowding

L Taraval Street Scenes

Muni includes many heavily used bus lines.  But the workhorse of the system is, or at least should be, the Muni Metro subway/surface system.

A fully grade-separated subway typically carries hundreds of thousands of riders a day.  Tokyo’s 9 lines carry an average of over 1,000,000 riders per day per line.  The Paris Metro’s 19 lines carry an average of 260,000 riders per line per day.  New York’s 22 subway lines average over 250,000 riders per line per day.  What makes this possible are long trains traveling frequently at regular intervals.

The Muni Metro is not fully grade-separated and station constraints limit the length of its trains.  Therefore the five Muni Metro lines cannot generate the huge riderships that are achieved by many subways throughout the world.  However, Muni Metro’s peak period carrying capacity is currently less than half of what it was designed to be and could again be.  In fact the five Muni metro lines today average only a little over 30,000 thousand riders per line per day, roughly a third what they could and should be carrying.  The Market Street subway is no longer doing the job it was designed and built to do.

This unacceptably low ridership is not because people don’t want to use the system.  It is estimated that were it not for excessive peak period crowding, Muni Metro’s ridership would climb by at least 40,000 riders a day. In other words, tens of thousands of would-be Muni Metro riders are pushed off the Muni Metro system every day because of excessive peak period crowding.  With traffic increasing and Muni surface vehicles slowing down, the lack of a fully functional Muni Metro system is becoming a bigger and bigger headache for anyone trying to get around in San Francisco.


Update on the ill-conceived M line plan


All that expensive tunneling (in green) to serve only the east edge of the Development?? A shuttle bus to a depressed Holloway Station would serve many more people and be much cheaper.

Some time back SaveMuni posted an article entitled: “A Roundup of Recent SFMTA Mistakes.” Mistake No. III describes the ill-conceived 19th Avenue/M-Line tear-up.

Despite the absurdity of this project, the SFCTA and SFMTA are ploughing ahead, pointing to a $70 million “contribution” from the developer of the Park Merced Project as justification for spending between $1.2 and $2.0 billion of the taxpayers’ money to put the Muni M-Line in a subway along the west side of 19th Avenue in order to facilitate a tunneled detour a short way into the Parkmerced Development.

SFMTA Approves Muni Service Increase

(Exerpted from SF Bay January 21, 2015)

Seniors and disabled Muni riders weren’t the only ones benefiting from a better financial picture for San Francisco’s transportation agency over the next two fiscal years.The San Francisco Municipal Transportation Agency’s board of directors are moving ahead with a 7% Muni service increase, additional funding for cleaning Muni vehicles and eliminating telephone and online transaction fees charged for making a citation payment to the SFMTA.

The board last April included all of these programs in its two-year budget last year, which included free Muni for low-income seniors and people with disabilities, but was contingent on how the transit agency’s financial health looked like this month.

In a report (presented to the SFMTA Board at its regular meeting on January 20th), the transit agency said it would be able to financially support the increase in Muni service and the additional funding to hire more staff to clean Muni vehicles of graffiti and tagging.

The transit agency projects higher revenues (from) transit fares, parking fees and fines and also (from) more funds from The City because of current (improving) state of San Francisco’s economy.

The 7% increase in Muni service approved Tuesday by the SFMTA Board follows a 3% increase approved last April.

Muni riders will begin seeing some of these service increases starting January 31st, including the launch of Muni’s new 55-16th Street route and increased frequency on the 44-O’Shaughnessy line. A soft launch of the new route is set for January 26th, according to SFMTA Director of Transportation Ed Reiskin.

The SFMTA said the rest of Muni ‘new service will be phased in starting this Spring and continuing during next Fall and Winter.

Transit officials also approved an additional $1.8 million for the SFMTA to hire additional staff to increase the cleaning intervals of Muni vehicles. Of the $1.8 million, the transit agency dedicated $600,000 through the current fiscal year and $1.2 million for the 2015-2016 fiscal year.

The transit agency also got rid of its $2.50 transaction fee charged to people who pay their citations from the SFMTA online or by telephone, which will take effect on May 1.

Mayor’s Transportation Task Force Misses the Mark

Early in 2013 Mayor Edwin Lee announced the formation of a 46-person Transportation Task Force, convened to develop a long range transportation plan for San Francisco. The intent was to convince voters to pass a General Obligation Bond Issue, extend the 1/2 cent transportation sales tax and increase San Francisco’s Vehicle License Fee. This was expected to raise a total of $2.955 billion, to be spent over the next 20 years on assorted projects selected by the Task Force.

Unfortunately the Task Force was comprised mostly of inexperienced individuals brought in to help win support for the funding measures to be placed before the voters rather than pursue sound transportation planning. Most members of the Task Force had little if any experience in the transportation field, particularly with respect to Muni and its huge backlog of unfulfilled capital needs. A quick review of the 27 projects proposed by the Task Force in its report released in November 2013 in shows that the result of the effort was a “transportation plan” in name only.


A Critique of SFMTA’s TEP

SaveMuni has completed an analysis of the SFMTA’s Transit Effectiveness Project (TEP), which clearly represents a great deal of investigation and hard work. Following is a summary of our findings:

1.) Meeting TEP Objectives:  At the beginning of the report the TEP lists some very well-stated general objectives. However, when developing the detailed improvements that comprise the essence of the TEP, the planners paid little attention to these goals. There is a need to evaluate each TEP proposal in order to ascertain the degree to which it conforms to the important objectives set forth in the Policy Framework (Pages 2-19 to 2-23) and make adjustments in the proposed improvements accordingly.

2.) Stockton Street Overlooked:  TEP planners say they want to improve transit operations on Stockton Street. Achieving this objective would require speeded up loading and unloading coupled with greatly improved service reliability. Low-floor, articulated buses would speed up loading and reduce crowding. Consistent police enforcement of existing traffic laws would help keep the streets clear. Getting the southbound 8x Line buses off Stockton would reduce the tendency of the three lines now operating on the street to get in each other’s way. In its report entitled “Stockton Surface Improvements” SaveMuni identifies 8 specific changes that together would materially improve Chinatown surface bus operations. According to SFMTA projections, 89% of the users of the three Stockton Street bus lines will continue ride the buses even after the Central Subway goes into operation. It is therefore imperative that the SFMTA bring the Stockton Street bus service up to standard.


19 Steps to a better Muni

Unlike an outlying suburban area, San Francisco is a densely built-up city in need of a world class public transit system. When Muni falters, the lives and livelihoods of 700,000 daily riders and 60,000 reliant small businesses are immediately affected. Because of SFMTA’s fiscal and operational problems, Muni currently fails to provide consistently reliable service on its 75 bus munistepsand rail lines.

Until this changes, beleaguered Muni riders will continue to experience slow downs and gaps in service, vehicle breakdowns and frequent over-crowding.  Fixing these problems will require basic changes to the current program.  Needed most are smart planning, optimal deployment and operations, improved street conditions, a superior vehicle maintenance operation, changes in working rules and effective use of capital.

With persistence, strong management and smart policy-making, Muni is capable of providing truly excellent service to riders and would-be riders.

Here are 19 proposals designed to get to that point 


Problems with the SFMTA’s Plan

The Central Subway is SF’s Gravina Island Bridge

SF Weekly’s Eskenazi sums it up:

September 23, 2013:  Everyone now knows that the Central Subway is and always has been a weak project, doggedly promoted for foolish reasons.  However, the plan to remove the used-up tunnel boring machines (TBM’s) through a large hole located 2,000 feet north of the end of the subway at the site of the old Pagoda Theater pushes things to new extremes.

The SFMTA (the agency running Muni) insists that it must spend an extra $80 million in this unneeded tunneling and hole-digging for the sole purpose of “saving” two TBM’s worth a total of $4.5 million.  Does that make sense?

If this cockamamy plan goes through, it will reportedly be the first time in history that a tunnel anywhere in the world has been extended substantially beyond the end of a subway in order to recover used-up tunnel boring equipment. Elsewhere tunnelers either disassemble the machines and back them out the way they came in, or bury them in an out-of-the-way place (in this case under Jackson Street)

Over the past year numerous individuals and groups have tried to get the SFMTA to explain why it wants to dig a huge TBM extraction hole in North Beach. To no avail. Apparently fearful that its financially shaky house of cards will collapse, the SFMTA has consistently refused to answer the question or even discuss the subject.  Yet the absurd $80 + million plan, which the SFMTA insists is needed to save two TBM’s worth a total of $4.5 million, plows ahead.  As a result, North Beach and in particular the affected residents and businesses near the construction site have already experienced construction noise, falling debris and other effects…with the digging yet to come.

For this and other reasons the SFMTA now acknowledges the project contingency reserve, once ballyhooed as being $330 million, is now mostly gone.  The latest figures show the reserve as having dropped to around $50 million or 3% the cost of the project (far below the federal government’s requirement of 10%) with much difficult construction work yet to come.

According to a risk management analysis completed by the Federal Transportation Administration and SFMTA March of 2010, the project appears destined to go significantly over budget.  The FTA/SFMTA report concluded that the project had only a 30% chance of staying within its $1.58 billion budget and only an 80% chance of holding the overruns to less $400 million.  Under federal rules, the local sponsors of New Starts projects pay for all overruns.  Which means that the San Francisco tax payer could be saddled with paying for extra Central Subway project costs of $400 million or more. This is a risk that should be –  but apparently isn’t – of concern to all of San Francisco’s elected officials.

More about SFMTA’s incursion into North Beach

Here is a chronology of the events that have led up to the current debacle.

June 2012:  SFMTA announces plans to tear up the heart of North Beach by extending its tunnels 2,000 feet north of the Chinatown terminal station, allegedly because of a need for a suitable site from which to extract two tunnel boring machines (TBM’s).  This causes a firestorm of opposition from North Beach merchants and residents, furious over the idea of digging a 42 foot deep, 45 by 49 foot hole in the middle of Columbus Avenue.

September, 2012:  SFMTA thinks better of the Columbus Avenue idea and instead proposes to pull its TBMs out of the ground at the privately-owned Pagoda Theater site on Powell Street near Filbert.  Negotiations with the private property owner ensue.

February 15, 2013:  The SFMTA announces that the shift to the Pagoda site would increase the overall cost of the Central Subway project by $9.15 million….money it says it would divert from Muni’s already overburdened operating budget.   (The cost of the shift has since climbed to $13.7 million and is destined to rise still further).  In view of a project contingency reserve that the SFMTA has at various times put between $150 million and $330 million, it is not clear why the cost of the Pagoda shift should come from Muni operating funds rather than Project funds.  Here are two possible explanations:

a.)  The contingency reserve has already been used up.

b.)  The Feds won’t play ball because they now realize that extending the tunnels 2,100 feet beyond the Chinatown terminal has nothing to do with TBM extraction and everything to do with someone’s dream of a future Phase 3 * extension to Fisherman’s Wharf).

*  Phase 3 is a fantasy.  An extension to Fisherman’s Wharf was not described or even mentioned in the Central Subway EIS/EIR. No local, regional, State or federal agency has approved it or provided any funding for it.  Since Muni already provides ample bus and rail service to Fisherman’s Wharf, there is no discernable reason for giving this pet idea precedence over Muni’s many other pressing capital needs.

April 28,  2013: As indicated, despite its growing lack of credibility, the SFMTA continues to claim that digging a big hole in North Beach is the only way of recovering its TBM’s.  If the SFMTA were to “get real”, by removing or otherwise disposing of its TBM’s in the conventional manner, it could save the project at least eighty million dollars, with absolutely no loss of subway functionality.

Nevertheless the SFMTA is pushing ahead with its TBM extraction plans, undermining important environmental safeguards and running roughshod over affected businesses and nearby residents in the process.   EIS’s and EIR’s are supposed to ensure that the environmental impacts of a proposed project are carefully and accurately described and evaluated before construction begins.  By proceeding into an unknown, unapproved and unfunded Phase 3, all in the name of TBM extraction, the SFMTA is making a mockery of NEPA and CEQA regulations and guidelines.

Litigation News

Updated April 28, 2013:  The Central Subway project remains vulnerable to litigation.

At least one pending action against the California High Speed Rail Authority would deny the Central Subway project $61.3 million in State Proposition 1A high speed rail funding.

In September 2012 an action was filed by a North Beach resident.  In this case the plaintiff charged that the reasons stated in the EIR for pushing the subway 2,000 feet beyond the Chinatown terminal into North Beach were bogus.
Despite its merit, the lawsuit was thrown out on technical grounds.’s Union Square Action:  A separate action filed by SaveMuni in October challenged the SFMTA’s right to extend a Central Subway station into a public park (Union Square), without the approval of the voters, as required under SF City Charter Section 4.113.  While this action also showed legal promise, the case was blocked by a City Attorney demurrer upheld by the Superior Court Judge assigned to the case.  Because of a lack of funds it was not possible to appeal the ruling.

SaveMuni’s North Beach Action:  On February 5, 2013, a letter from Lippe Gaffney and Wagner LLP,’s attorneys, was delivered to the SFMTA.  The letter raised substantive concerns and legal objections to the SFMTA’s plan to extract its tunnel boring machines (TBM’s) at the recently-selected Pagoda Theater site, located on Powell Street near Filbert.  For a variety of reasons, including potential geotechnical and ground water problems, potential ground subsidence, threatened historic structures and threatened incursions into public parks, believes that before disrupting and otherwise affecting North Beach in order to extract its TBM’s, the City should prepare and certify a subsequent or supplemental Environmental Impact Report.  The funds needed to pursue this valid case also appear to be lacking.

More Facts about the Central Subway

Bypasses Market and Mission Street transit riders

Market/Mission Disconnect:  From the Union Square Station, Central Subway riders attempting to reach a Market Street subway train would be obliged to travel on foot the distance of 4 football fields placed end to end to make their connections.  Similar walks would be required to transfer to the Mission Street buses.  Even getting to a Market Street bus would be substantially less convenient than it is today.

Reroutes today’s T-Line riders away from Important Destinations

The Central Subway would disconnect Muni’s existing light rail T-Line riders from the the baseball park, future basketball pavillon, Embarcadero, Market Street Muni Metro and BART subway stations, ferry boats, Transbay Transit Center and future high-speed trains.  Instead T-Line riders would be taken by Central Subway to the Convention Center, upscale Union Square shopping area and southern part of Chinatown.

Fails to Serve East-West Bus Riders

Today’s Stockton bus riders can easily transfer to Muni LRV lines J, K, L, N, M, F and T and to Muni east-west bus lines 1, 2, 3, 5, 6, 9, 9L, 10, 12, 14, 14L, 14x, 21, 31, 71, 71L and 76.  With the Central Subway, connections to every one of these 24 east-west Muni lines, as well as to four BART lines and the Mission Street  SamTrans buses would be substantially less convenient from the subway than from the buses currently operating on Stockton Street.   In addition, most Central Subway riders would experience longer total trip times via subway than via today’s Stockton Street buses.

Note:  To help pay for the subway, the SFMTA plans to cut service on the 30 and 45 trolley bus lines by 50%.

Fails to Serve Anyone Much North of Jackson Street

Because the Central Subway stops at the Washington Street terminal it does nothing to accommodate the outlying riders of the 8x, 30 and 45 bus lines.  For this reason it fails to serve not only the northern two-thirds of Chinatown but also Muni riders from the Cow Hollow, Presidio, Marina, Buena Vista, Fort Mason, Polk Gulch, Russian Hill, Telegraph Hill, and North Beach neighborhoods.

Fails to Serve Much of Western San Francisco

Because of the aforementioned missed connections most riders from the Richmond, Sunset, Castro, Twin Peaks, Presidio Heights, Pacific Heights, Nob Hill, Hayes Valley, Haight-Ashbury, Western Addition, Forest Hill, OMI, and Mission neighborhoods would find the Central Subway even less convenient than today’s slugglish Stockton Street buses.

Is much Deeper and more Expensive than Necessary

clip_image008Unnecessarily deep tunnels and stations require long escalator rides.  When the escalators go out of service as they often do, it means either a slooooow elevator ride or long treks up and down stairs.

A mezzaine level, not required for a low ridership line like the Central Subway, unnecessarily pushes up construction costs.

Has Limited Future Carrying Capacity (updated September 17 2014)

To save money, the LRV platforms were reduced to two-car lengths (potentially expandable to three).  Short platforms serve only short trains, ruling out a higher capacity operation in the future.

Fails to Meet the Challenge

If the eastern San Francisco’s north-south transportation system had been laid out and designed properly, Muni riders would have traveled unfettered by traffic congestion from one
end of San Francisco to the other on fast buses or trains.  Connections to the BART and Muni Metro subway systems would have been quick and easy. Chinatown would have been served by two stations, one near the #1 bus line; the other near the #10 and #12 bus lines. Stations would have been conveniently located just below street grade. A well designed system could have provide much better transit service at much lower cost than the cost of the Central Subway.

In the place of what could have been San Francisco will eventually be saddled with a deep and enormously expensive short subway projected to carry only a small fraction of what city subways normally carry.

The SFMTA’s Central Subway is fatally flawed.  Here are five of them:

1.)  By ending at Washington Street, the proposed subway would be of little use to anyone living north of that point. Today, the Muni’s 30 and 45 electric bus lines serve riders traveling to and from Chinatown, North Beach, Telegraph Hill, Russian Hill, Polk Gulch, Fisherman’s Wharf, Union Street, Cow Hollow, the Marina District and the Presidio of San Francisco.  All of these riders bound for points north of about Jackson Street would be obliged to continue using buses that would continue to bog down in heavy surface traffic, particularly along Stockton Street.

2.)  By failing to serve all or even most riders of the 30 and 45 lines, the MTA’s plan would make it impossible to reduce bus operations sufficiently to cover the extra cost of the subway operation. As a result the MTA would be obliged to operate both a very expensive subway deep underground and a substantial surface bus operation; thereby digging the Muni’s fiscal hole even deeper than it already is.

3.)  Because of extra walking and waiting times, most subway users will experience trip times actually longer than the trip times of today’s surface buses.  For more information on this subject see:  “Perceived Travel Times”

4.)  By rerouting the T-Line from its alignment along the Embarcadero and Market Street Subway to Chinatown, the project would disconnect riders from Mission Bay, Dogpatch, Bayview-Hunters Point, Little Hollywood and Visitation Valley and the rest of southeast San Francisco from the Market Street Subway.  Those with Market Street or Market Street subway destinations would ride the Central Subway past Market to a new Union Square station, and then backtrack on foot a substantial distance to Market Street or the Powell Street Station.

5.)  Because of the depth of the subway, the short distance between the Washington and Union Square Stations and the extra walking and waiting time required to use the subway, most people, especially if they are transferring to any of the east-west Muni lines crossing Stockton and Fourth Streets, will find riding the subway less convenient than today’s bus trip.  Having to walk several blocks to a subway station at Washington Street, then descend seven stories to the subway platform, then riding the subway less than half mile to Union Square, then ascending to mezzanine level and then walking an additional 1,000 feet to a BART or Muni Metro LRV platform is not likely to attract many riders.  In addition, transfers from the subway to most of Muni’s east-west bus lines would be longer and less convenient from the subway than from the buses now operating along Stockton Street.  The SFMTA likes to call its Central Subway the Chinatown Subway.  Yet according to the SFMTA’s own EIR/EIS, once the first blush of newness has worn off, only 10% of the riders of the Muni 8x, 30 and 45 bus lines riders will bother to use the Central Subway.

Neglected Alternatives

Chinatown needed and deserved a reliable and expeditious connection to downtown San Francisco, as did the rest of northeastern San Francisco. Here are some of the neglected alternative ways of achieving that objective:

a.)  Some of Muni’s No. 30 and 45 electric buses as well as the T-line light-rail vehicles could have used the subway. Buses could have come to grade through portals located north of Broadway. This would have enabled the rest of Chinatown and residents of the nine neighbohoods to the North of Chinatown to benefit from the subway. If the bus lines had been extended southward, Mission Bay and Potrero Hill could also have benefited.

b.)  The subway could have been shallow instead of deep. Going shallow without the mezzanines would have allowed both an efficient Market Street station and two well-located Chinatown stations.  Locating the subway over rather than under the Market Street subway lines would have improved access for riders, allowed for longer stations, better electric bus accommodation at much lower cost.

c.)  To cut costs, buses or light-rail vehicles could have operated in a median of Fourth Street until they crossed Mission Street, at which point the transit vehicles could have proceed in a shallow subway under Market and Union Square to Chinatown.

d.)  By speeding up bus loading and by reconfiguring Stockton and its nearby streets in a manner designed to improve bus flow, calm traffic and make things easier for pedestrians, Muni’s surface bus operation could have been (and in fact still can be) significantly improved.

e.)   Implementing a congestion pricing system for San Francisco could also have been given greater attention.

None of these alternatives was adequately addressed, either in the Central Subway EIR/EIS or in public discussions.  For more information on this subject see “Better Alternatives”.

SFMTA’s Central Subway Plan

The original idea was to please a Chinatown power broker unhappy at the prospect of losing the Embarcadero Freeway.  The plan was to give her a subway to Chinatown.  Unfortunately things didn’t work out.  Here is an overview of what went wrong.
For starters the project was too costly.  Way too costly.  In fact at $1.58 billion for a mile of subway and a half mile of surface line, the Central Subway, if actually built, would become one of the most absurdly over-priced short stretches of rail line in the entire world.  
It gets worse.
