>The root cause of the disruption was related to network devices having intermittent connectivity. Staff in the Operations Control Center lacked the visibility of the track circuits and the train positions necessary for safe operations. Visibility of this system in the Operations Control Center is required to run service.
> BART’s Network Engineering team identified and isolated a redundant sector of the network that was causing intermittent visibility and disconnected it. This allowed service to begin.
