There was no BART service for several hours Saturday morning after a glitch interrupted BART's traction power supply system and impacted the train control routing system.

As BART officials tell CBS SF, the problems began around 2:45 a.m. and lingered past the system's opening time at 6 a.m., meaning that stations all remained closed until around 9 a.m.

BART spokesperson Cheryl Stalter announced in a voicemail at 9:03 a.m. that train service had resumed in all but those lines south of Daly City. Trains are now running throughout the system, and an update is due later in the morning as to when service to SFO and other stations south of Daly City would resume.

Mission Local noted via some people stranded in the Mission trying to get home to the East Bay that BART didn't post any sort of notification on its app which — that would be helpful.

As NBC Bay Area reports, via Stalter, both the traction power supply system and train control routing system are essential to BART's operations, and both took a number of hours to get back up and running.
