BART was down systemwide this morning due to computer equipment issues, but all train lines are now up and running. East Bay service resumed around 9:30 a.m. and service in San Francisco and the Peninsula resumed at 11:45 a.m., according to BART’s X feed. Expect major residual delays, though, BART warned commuters.

While the trains were still down, MTA workers at the 24th and Mission BART station waived commuters away. The station was totally deserted, with caution tape has been placed over the turnstile entrances.

“I’m already very late” to work, said Madeleine, a commuter at the 24th BART station who planned to take bus instead. “I’m surprised … I just assumed it would be running.”

While the trains were down, BART urged commuters to find alternative means of transportation, including taking AC Transit buses over the bridge. MUNI allowed commuters affected by the BART shutdown to ride for free between Embarcadero and Balboa Park, BART’s first and last stops within San Francisco.

BART says the computer issues were triggered by upgrades that BART made to its computer network system overnight, which allows different parts of BART’s system to communicate with each other.

  1. BART sucks. Let’s face it. It could be better, it’s not, and people still rely on it.

    It shouldn’t cost what it costs, it shouldn’t break down weekly, and it shouldn’t be unsafe.

  2. >>> “…upgrades that BART made to their computer network system overnight…”

    Shouldn’t major upgrades be performed on a Saturday night/Sunday morning so that the resulting meltdown doesn’t impact the Friday commute?
