June 10 Muni Service Changes Adds Service on Connector Routes By Clive Tsuma The 38R Geary Rapid will run every 6 minutes starting June 10 Starting Saturday, June 10, the SFMTA will be adding Muni service on several lines to address crowding, wait times and to support increased summer tourism. We’re also making some stop changes to serve more customers and make the service more accessible and reliable.  Increased Service  To address crowding and reduce pass-ups, we’re adding service on the 1 California between Clay and Drumm streets and California Street and Presidio Avenue – where demand is highest – on weekdays from 7 a.m. to 7 p.m.  We’re also going to be starting service earlier on the 1X California Express, at 7:30 a.m. instead of 8 a.m., in response to customer feedback, as well as adding stops at Cherry, Spruce and Laurel streets and Presidio Avenue.   We’re also extending the evening service to the Presidio at 30 Stockton seven days a week.

Heads Up: Fix On The Way For Two-Car Trains

Heads Up: Fix On The Way For Two-Car Trains
By

N Judah LRV4 picking people up inside the subway

We want to inform our riders about a recent issue that arose on one of our new LRV4 Siemens vehicles. While Muni LRVs remain safe to operate, out of an abundance of caution, we will be limiting the number of two-car trains in service for the near future. We’re taking this opportunity to explain some of the history and what our plans are to fix the problem.

Last April, our two-car trains started to experience complications with their couplers. Couplers are a train component that allow multiple vehicles to operate under the control of one operator. Upon inspection, we found broken shear pins that were a symptom of a design flaw within the coupler. To fix this, we replaced the old pins and the couplers began working properly.

Since the April 2019 coupler issue on our LRV4 trains, Siemens has continued its investigation into the cause of those failures. On Monday, we received word from Siemens about ongoing and unexplained fatiguing, (meaning some pins are wearing out sooner than they should) and they proposed additional testing to identify the source of the fatigue.

Yesterday, we experienced a coupler failure, the first since April.

What Happened?

Wednesday morning, the coupler shear pins failed on one of our LRV4 trains while in revenue service. The cars did not separate. The operator reported the issue to her supervisor, the passengers disembarked and the train was taken out of service.

Why Did It Happen?

There does not appear to be a single event (collision, etc.) that caused the failure, but our investigation is ongoing. 

How Are We Responding to This?

In the short term, the plan is to replace the coupler shear pins on all LRV4 trains. The medium-term plan is to redesign the shear pin and look for a permanent solution. Siemens has agreed to provide an ongoing supply of shear pins while they work on the redesign and is activating their global resources to make this happen.

What Does This Mean for Service?

On a typical weekday, we have been running approximately 20 two-car trains in the system. Beginning yesterday, the operation of two-car trains was limited until new shear pins could be installed today. Tomorrow, we will operate three or more two-car trains. These are trains that have received the new shear pins. We are expecting a shipment of shear pins today (four per train) and expect to be able to run as many as seven two-car trains by Monday.

Who Will Pay for This?

These repairs are covered under warranty by Siemens and will be replaced at no cost to San Francisco taxpayers.

Is It Safe?

Yes, safety is our number one priority. Siemens has confirmed that with newly installed pins the couplers can safely operate and the new pins can be safely used for up to 120 days.

The Future of Transit Service Through the Health and Budget Crisis

-
The Future of Transit Service Through the Health and Budget Crisis By Jeffrey Tumlin The pandemic has upended every aspect of our society, and the SFMTA is no exception. The COVID-related health and financial crises have resulted in deep and painful cuts to Muni service. We will be draining our fund reserve and spending one-time money just to sustain the service we have. Absent new outside funding, we fall off a financial cliff in 2023, just as the city needs us the most to support its economic recovery. As your Director of Transportation, I want to be open and transparent about how we got here and what it means for you. When I took this job six months ago, our mobility systems were strong but inefficient, the result of too many years of avoiding hard or politically unpopular choices. This crisis has now forced us to make those hard choices. It has also demonstrated the SFMTA workforce’s depth of talent and creativity, and its capacity for collaboration and strategic risk-taking.

Ride to Chase Center Events Along the New T Third By Christopher Ward Starting January 7, take the S Shuttle Mission Bay on the new T Third line via Central Subway to Chase Center events. Service on the new T Third Line from Chinatown Rose-Pak to Sunnydale starts January 7. With it , new event service to Chase Center will also start via Central Subway on the S Shuttle Mission Bay. During events at Chase Center, shuttles will operate between Chinatown-Rose Pak Station and UCSF/Chase Center every 10 minutes. These shuttles will start approximately two and a half hours before an event and continue for two and half hours after an event. From Chinatown to Chase Center, riding the S Shuttle Mission Bay takes about 20 minutes. Best of all, your Chase Center event ticket is your Muni fare. No additional Muni fare needed ! Both electronic and physical tickets for events – including Warriors games, concerts and other events – will serve as  proof of payment  for Muni service throughout
