On the morning of Friday, May 9, 2025, at around 5 a.m. PDT, the Bay Area Rapid Transit (BART) system experienced a devastating service disruption due to a networking issue that affected its train control systems. The entire system shut down. A complete suspension of train services across the entire network occurred, which included routes to San Francisco International Airport. Service was gradually restored by approximately 9 a.m., but many delays continued.
BART Malfunctions
The main cause of the malfunction was found to be a failure to power up the necessary systems to safely operate trains. The incident was not related to a cyberattack, but it did highlight many vulnerabilities in BART’s aging infrastructure, which still relies on 1960s-era systems. Despite trying to identify ways to modernize the train control system, the system continues to have a looming financial crisis, including an anticipated $300–$400 million annual deficit once emergency funding ends. This financial struggle threatens severe service cuts, undermining recent efforts to enhance reliability.
During the shutdown, commuters were directed to use alternative transportation options such as buses, trams, and ferries. The disruption affected several thousand riders, including those traveling to the airport, and caused many delays during the morning rush hour.
BART Needs Funding
System officials have emphasized the significant need for increased, ongoing funding to maintain the safety of the transit system and prevent future service disruptions, and ensure the long-term functioning of the transit system that thousands of commuters rely on. Transit advocates and lawmakers are calling for long-term investments, possibly through a proposed transit sales tax, to address the agency’s financial challenges and aging infrastructure.
