The first Muni Metro Fix-It Week of 2023 was a resounding success in March, and it’s also the first Fix-It Week since the SFMTA launched the Central Subway in early January of this year. Here is a behind-the-scenes video recap. Fix-It Week is the SFMTA’s quarterly effort to optimize work time by closing Muni Metro early for critical maintenance. The SFMTA’s Maintenance of Way (MOW) teams did an excellent job maintaining the subway and preventing future breakdowns. 

Fix-It Week helps the Muni Metro get a 20% improvement in speed and about a 20% improvement in reliability in the subway. It takes fewer minutes to take the N Judah from the Outer Sunset to Embarcadero now than it did in 2019. 

 From March 16 to March 22, 2023, the Muni Metro Subway between Embarcadero and West Portal closed at 9:30 p.m. to provide SFMTA maintenance crews an extended window to perform underground infrastructure improvement work that cannot be completed during the usual overnight windows. During the subway closure, buses provided substitute service for Muni Metro lines on the surface and connected all stops on Market Street.

The goal of Fix-It Week is to make Muni metro subway operations more reliable, ensure safety, and improve the customer experience. Nine MOW teams, Track, Cable Car, Motive Power, Maintenance Engineering, Mechanical Systems, Overhead Lines, Underground, Paint Shop and Signal, were involved in the maintenance work. 

Major maintenance work includes: 

  • Track replacement and reinstallation from the Ferry Portal to the Van Ness Crossover 
  • Mechanical systems cleaning, maintenance and installation  
  • Signal repairs and upgrades, including the demolition of old train control system racks, equipment and wiring 
  •  Track fastener and subway lighting surveys, and drain cleaning around switches  
  • Overhead Line inspections and Overhead Section Break hardware adjustments 
  • Debris removal and traction power substation inspections 
  • Cable Car maintenance and repairs

The SFMTA teams completed over 2,000 hours of maintenance and inspections over the seven night shutdown. They were able to perform 161 feeder operations, replace more than 125 bulbs for trackway lighting in multiple locations, renew 750 feet of Overhead Contact System contact wire, replace eight blue light phones and inspect approximately 8,000 track fastener plates from the Ferry Portal to Powell Station.

A support team was also contributed to the success of Fix-It Week. These staffers helped coordinate maintenance work, upheld all safety standards and ensured that subway service resumed on time every day. 

The SFMTA will continue to keep the Muni Metro system in a state of good repair. The next Fix-It Week is scheduled for July 2023, and we thank you for your patience and understanding while we do this vital work.

Have Feedback on the COVID-19 Muni Temporary Service Plan? By Shalon Rogers In March 2020, due to unprecedented constraints on resources brought on by the COVID-19 pandemic, the SFMTA had to make significant transit service reductions. As of January 2021, the agency has been able to restore service to a level where 91% of San Franciscans are within a quarter mile of a transit stop. This is reflected in the SFMTA’s current  COVID-19 Temporary Service Plan .   ' COVID-19 Temporary Service Plan Map The SFMTA is committed to ensuring that our programs and services are  compliant with Title VI of the Civil Rights Act of 1964  and therefore do not have a discriminatory impact based on race, color or national origin. As part of this work, we conducted a Title VI service equity analysis to evaluate the current COVID-19 Temporary Service Plan. The results of this analysis will be presented to the MTA Board of Directors on May 4. The public is invited to attend and provide comments on
