Context:

Commuter trains in the San Francisco Bay Area resumed service after an hours-long shutdown caused by a malfunction on Friday morning. The Bay Area Rapid Transit (BART) system was unable to operate due to a failure in powering up its train control system, halting operations and affecting thousands of commuters. This disruption occurred just after 5 a.m., and full service was only restored by 9 a.m., impacting morning travel, including routes to San Francisco International Airport. In response, alternative ferry and bus services were deployed to assist passengers in reaching their destinations. The root cause of the malfunction was not immediately identified, leaving the system's reliability in question for affected commuters.
