As of 8:10 a.m. however, normal service is running on all lines.
BART officials said crews were working in downtown Oakland to fix 10 to 20 feet of damaged covering for the third rail of the track.

The track damaged is underground near 12th street and crews had to shut power down near that section to get specialized equipment.
Officials say the damage was caused by a maintenance vehicle we use during the overnight hours.
