The Bay Area Rapid Transit (BART) system crashed Friday morning, September 5, leaving 180,000 daily riders without trains. Officials blamed a computer equipment failure linked to overnight network upgrades. Commuters were urged: “Don’t travel today.” Roads, buses, and ferries struggled under the pressure as the Bay Area faced its worst transit nightmare in years.
BART Shutdown Freezes the Bay Area
The entire BART system shut down Friday morning, September 5, 2025, stranding tens of thousands of commuters across the San Francisco Bay Area.

Instead of the usual 5 a.m. start, stations remained dark and silent. By 7 a.m., platforms were empty, trains sat idle, and traffic on highways leading to San Francisco began to choke.
No Timeline for Restart

Transit advocates say today’s crisis highlights BART’s aging infrastructure and the urgent need for more resilient upgrades.
Alternatives for Riders
BART directed stranded commuters to its Trip Planner tool and an alternatives page (bart.gov/alternatives) offering guidance for buses and ferriesStart of BART service delayed F….
Main alternatives included:
- AC Transit Transbay buses between Oakland, Berkeley, Richmond and San Francisco.
- San Francisco Bay Ferry routes from Alameda, Richmond, and Oakland.
- Carpooling services and rideshare apps, which saw a surge in early-morning activity.
Despite these measures, demand far outstripped capacity, creating gridlock across the Bay Area.
What Happens Next?
BART officials have not given a timeline for when service will resume. Riders remain frustrated that a planned network upgrade caused a total system collapse instead of increased reliability.
This raises serious questions:
- How can a single computer problem disable an entire regional transit system?
- What safeguards are in place to prevent a repeat of this disaster?
As one San Mateo commuter put it: “You just roll with the punches — but this is happening too often. BART can’t keep failing like this.”bart_ All BART trains halted af…
