The primary transit system in the San Francisco Bay Area was forced to shut down all trains on Friday morning because of a computer problem, sending commuters scrambling to find alternatives with little notice.
Bay Area Rapid Transit, which transports more than 170,000 passengers on weekdays throughout much of the region, said service had been suspended because of a “computer networking” problem. Riders were searching for alternatives, from car pools to local bus services and ferries.
It was not immediately clear what had caused the networking problem or when service was expected to continue. Shortly after 7 a.m., traffic was thick at the freeway to the Bay Bridge, which connects Oakland and other East Bay communities to San Francisco.
This is a developing story. Check back for updates.
