OAKLAND (CBS SF) — BART is resuming normal service systemwide after a computer glitch brought service to a halt earlier Saturday morning.

BART reported at 10:50 a.m. that normal service was being restored at all stations. It had restored limited service shortly after 9 a.m.

The service problem originated at 2:45 a.m. with a computer network failure, BART spokeswoman Cheryl Stalter said. It was not related to crews working overnight on BART’s uninterruptible power supply in Oakland, as was originally believed, she said.

BART will conduct a forensic evaluation to determine what caused the network failure, Stalter said. It is expected to take several days.

Tammara Dozier expressed the frustrations of thousands of Bay Area commuters when she described her thwarted morning commute to KPIX 5’s Da Lin at the Powell Street station in San Francisco.

“Horrible. It’s cold and raining and since BART opened up at 6 a.m. it’s not been working and it’s about to be 9. I’m trying to go to Warm Springs so I can go to work. I clean houses and so I have a client … in Santa Clara. My client’s understandable, thank God, but still — it’s annoying!”
