BART service has resumed system-wide following a major disruption Thursday morning caused by a computer networking problem that halted train service across the entire system. While trains are now running again, BART officials warn that riders should expect residual delays of approximately 20 minutes as the system recovers.

The outage, which began earlier this morning, led BART officials to urge commuters to seek alternate means of transportation. As of 10:05 a.m., BART announced that service had resumed but warned of “major delays toward all destinations.” A follow-up update around 11 a.m. confirmed continued delays due to the earlier train control issue.

On social media, AC Transit warned riders to anticipate increased crowding and possible delays due to mutual aid service during the BART outage and suggested riders consult their online tracker for real-time updates.

This marks the second time in a year that a major BART disruption has occurred around this time. Almost exactly one year ago, a system outage at the Richmond station halted service to MacArthur, was also tied to technical issues.
