UPDATE: Normal service has resumed on all lines as of 8:46 a.m.

Bay Area Rapid Transit said that service restoration is in progress after emergency repairs shut down transbay service early Friday morning.

BART officials reported major delays systemwide and no transbay service as crews worked on track repairs in Downtown Oakland. The system reported Friday at 5:43 a.m. there was no Red Line or Green Line BART service.

As of 7 a.m., the agency said it had restored limited service.

Earlier, officials reported BART was temporarily suspending transbay service due to the emergency track repairs and recommended riders seek alternate transportation to travel across the San Francisco Bay.

Crews were working to repair a damaged section of the third rail of the track in an underground section in Downtown Oakland.
