San Francisco BART trains go dark systemwide due to ‘computer networking problem'
San Francisco's BART trains went dark systemwide Friday morning due to a computer networking problem, the transit agency said on social media.
"Due to a train control system problem BART service is suspended system wide until further notice. Seek alternate means of transportation," the agency said on X at about 4:25 a.m.
BART added later that crews are on hand, troubleshooting a "computer networking problem."
BART spokesperson Alicia Trost said the control center was unable to power up the system after its daily overnight shutdown.
"It does happen from time to time, our system is over 50 years old," she said. "The good news is we're in the process of replacing it, and we have the funding to do so because of Measure RR, and the federal government has made investments into our infrastructure. But it's awful news that the Bay Area can't rely on BART as of this moment. We don't have an ETA as to when the trains will go because part of that is identifying the location of the problem."
Trost added that crews have restarted all the system's servers to isolate and fix the issue. She said it could happen quickly or take up to a few hours.
