Aging Substation Fire Exposes BART's Biggest Infrastructure Vulnerability

A fire at a 1970s-era Daly City substation shut down transbay tube service for more than 48 hours this week, forcing BART's Board to confront the reality that 70% of its 74 substations are original equipment — each costing $60 million to replace. The disruption dominated a meeting that also delivered strong quarterly performance numbers, with customer satisfaction hitting 91.4% and crime per million trips falling 21%.

• Daly City substation fire causes BART's largest service disruption in recent memory — transbay tube shut down, no injuries, failed unit moved to top of replacement list
• Q4 performance review shows best safety index in years, 12,500-hour mean time between fleet delays, and ridership up 14% year-over-year
• Directors demand public-facing delay tracker, clearer disruption alerts, and Clipper 2 rider refunds after communication breakdowns left passengers confused
• Crime drops 21% per million trips as progressive policing teams conduct 2,577 wellness checks and divert 4,200+ calls from armed officers
• Public commenters warn BSV2 Silicon Valley extension could reach $14–15 billion, with design compliance failures threatening federal funding
• West Oakland TOD Phase 1 breaks ground with 200 affordable housing units starting construction in September

When the Lights Went Out at Daly City

A cascade of failures at BART's Daly City substation — starting with false signal occupancies, then a fire in the DC bus insulation, then a 34.5kV cable fault — produced a multi-day service meltdown that shut down the transbay tube and left riders scrambling for alternatives. No passengers were stranded, and there were no injuries, but the incident laid bare an infrastructure crisis decades in the making.

The basics: False occupancies in switches around Daly City began appearing Tuesday, likely triggered when HVAC equipment failed in the train control room, allowing excessive heat to scramble signals. That evening, a substation circuit breaker tripped and fire broke out in the DC bus insulation of the original substation. The 34.5kV cable also faulted. Service was progressively restored, with full transbay tube operations resuming at 11:30 p.m.

Why it matters: The failed substation was built when BART opened in the early 1970s. It had been identified as one of the top five substations needing replacement — but BART hadn't gotten to it yet. Roughly 52 of the system's 74 substations are original equipment, and each full replacement costs approximately $60 million. An overhaul — which extends life but doesn't solve the underlying problem — runs $3–5 million.

"This substation that failed is original. It was identified in the top five to be replaced. We already had scheduled to have a portable out there soon so that we could start taking it down," said AGM of Operations Sylvia Lamb. She added that the failure was unambiguous: "This is a very clear failure that is due to aging equipment. It's similar to the same fire that we had in KTT which was a couple of years ago."

Where things stand: General Manager Bob Powers confirmed the failed Daly City substation will be moved to the top of the replacement priority list, displacing another planned replacement. Director Janice Li pressed on the tradeoff: "What will not be done in response to us putting this at the top of the list? What other risks are we now creating?" Lamb confirmed that another substation's replacement would be deferred.

Director Liz Ames drew a distinction between routine delays and system-breaking events: "Not all delays are made the same. There are some delays that are like, okay, let me just text the person I'm meeting with, versus this has ruined my day, is going to affect my kids' pickup schedule."

Director Li also pushed for more public accountability, apologizing to riders directly: "I really want to apologize to our riders who've had some really terrible experiences over the last 48 hours. I don't know that we instinctively do that enough."

The Money Problem

At $60 million per substation and more than 50 needing replacement, BART faces a traction power bill north of $3 billion — a sum that dwarfs Measure RR bond capacity and will require either new voter-approved funding or a decades-long phased approach that accepts ongoing disruption risk. Overhauls buy time at a fraction of the cost but don't resolve underlying obsolescence.

Vice Chair Edward Wright argued the Board shouldn't wait for more fires to act, pushing for traction power to appear as an action-plan item in quarterly performance reviews: "Right now, if you look at this, nothing's wrong with traction power. And we know things are acting up and we're watching these issues, but we're not informing the public or the board about pending things."

Communication Failures Added Insult to Injury

Director Mark Foley called for a publicly accessible system delay tracker and proposed that disruption text alerts include direct links to alternative transit agencies like Muni and SamTrans. He also raised rider reimbursement: "As we shift to Clipper 2, I would like us to explore how we could reimburse riders, folks who were counting on us to get them somewhere."

Director Rash Ghosh expressed frustration with in-station PA announcements during the disruption, saying confusing messaging failed to prioritize SFO-bound riders. He also asked whether riders who entered the system but couldn't complete their trip were being charged excursion fares. GM Powers committed to follow up on Clipper charges and set up a communications walkthrough with Director Ghosh.

What's next: The failed substation moves to the top of the replacement queue. Staff will report back on Clipper fare charges during the disruption and explore a rider reimbursement framework tied to Clipper 2. Director Wright's push for traction power action plans in the quarterly review signals the Board wants proactive infrastructure risk reporting, not post-crisis briefings.

Strong Quarter, But Traction Power Looms

Record Safety, Rising Ridership

BART's Q4 FY2026 quarterly service performance review delivered the kind of numbers transit agencies dream about — right before the substation fire reminded everyone how fragile the gains can be.

Customer satisfaction reached 91.4%, up from the prior quarter. The safety index hit its best mark since the chief safety officer joined the agency. Mean time between fleet service delays reached 12,500 hours. Track delays were the best since FY2023, traction power the best since FY2022, and train control among the best since FY2021. Ridership climbed 14% year-over-year, with August finishing 6% above budget.

"Jeff Lau tells me, who's our chief safety officer, that it is the best we've had since he's been here," said AGM Lamb. GM Powers added that August saw "the top three ridership days since the pandemic."

Station improvements continued with LED upgrades completed at eight stations and three San Mateo-area "glow-ups" finished. New fare gate data now distinguishes accessible versus regular gates, and VATC upgrades reduced system boot-up times from minutes to seconds.

Director Li called for online performance dashboards accessible to the public, ridership breakdowns by line and station, and fare evasion measurement — pushing staff to make the data as transparent as the numbers are encouraging.

Crime Falls as Progressive Policing Scales Up

Chief of Police Kevin Franklin reported crime per million passenger trips fell from 4.68 to 3.68 — a 21% year-over-year improvement. Robbery incidents decreased by seven. Auto theft dropped 25% and auto burglary 10%.

The Progressive Policing Bureau conducted 2,577 wellness checks, diverted more than 4,200 calls from armed officers, and made 259 connections to service providers including the Gubbio Project, SOMA Rise, and Bay Area Community Services. Community intervention specialist engagement with disruptive behavior was up 83% year-over-year, with exits after CIS engagement rising 61%.

Priority one response time averaged 5.2 minutes, slightly missing the 5-minute goal. BART hired 11 new officers from 602 applications.

Director Robert Raburn celebrated the trendline: "It should just say more riders, less crime. And those two elements I believe are interconnected."

Director Li requested station-level CIS reporting, performance metrics for Mission plazas, and performance-based contracting with San Francisco — signals that the Board wants to measure progressive policing with the same rigor as train operations.

BSV2 Cost Alarms Grow Louder

Public commenters continued to sound alarms about the BART Silicon Valley Phase 2 extension in San Jose, with increasingly specific technical and financial claims.

Licensed professional engineer Barney Smitz told the Board that the BSV2 re-baselining has slipped from Q3 2026 to winter 2027, and that the $12.8 billion estimate has likely grown to $14–15 billion, with a $3 billion VTA funding shortfall. He said tunnel track slab configurations remain unpriced and designs are at best 30% complete despite claims of 60%. He also claimed that VTA-submitted design variances have been rejected by BART for failing to meet standards and safety codes.

A public commenter identified as Roland cited a 25-page PMOC special report he said was ignored by staff and referenced a VTA audit showing $2.1 billion in unreported expenses.

GM Powers noted the joint BART-VTA meeting has been rescheduled for Oct. 9 — a date the Board and public commenters will be watching closely.

Why it matters: BSV2 is BART's largest planned extension. If cost overruns and design compliance failures aren't resolved, they could jeopardize Federal Transit Administration funding that the project depends on. The gap between the public claims and staff responses continues to widen.

Farewell to a 46-Year Transit Veteran

The Board honored Dennis Markham on his final meeting day, marking the end of 46 years in transportation — 14 of them at BART. GM Powers and staff delivered emotional tributes praising his problem-solving abilities and positive attitude.

Markham credited Pam Herhold for recruiting him and expressed confidence in the internal audit and performance teams he built. His departure adds to a wave of senior retirements that is reshaping BART's institutional knowledge base — Director Raburn also noted the retirement of Director of Treasury Todd Morgan during the consent calendar discussion.

Director Victor Flores separately honored outgoing SEIU 1021 Professional Chapter President Olivia Rocha for her advocacy on behalf of BART workers. Rocha used her public comment time to raise concerns about network realignment and the reassignment of represented IT classification work to a non-represented probationary employee, requesting action to maintain proper labor classification boundaries.

BART's Original Fleet Gets a Second Life

The Western Railway Museum in Suisun City presented its new exhibit featuring three preserved legacy BART cars, a culmination of a seven-year volunteer effort that began under a formal donation agreement in 2022.

Bob Simon of the museum described the logistical challenges of moving BART's unusual 5-foot-6-inch gauge cars on standard gauge track using custom-fabricated dollies. The museum also acquired fare gates, control panels, test equipment, and historical documents. Curator Andy Payne announced the first version of his book, Selections from Legacy: The Story of BART's Old Cars. Princess Washington of the Bay Area Electric Railroad Association described the museum's 80-year preservation history.
