Bay Area Rapid Transit (BART) is experiencing major delays throughout the system during the Monday morning commute due to an issue involving the Transbay Tube.
The agency first announced the issue around 6:20 a.m., which involved an equipment problem on the track near the Embarcadero station. Trains were single tracking through the tube, which connects San Francisco and the East Bay.
As of 7 a.m., BART said there is no Red Line service between Millbrae and Richmond or Green Line service between Daly City and Berryessa / North San Jose. Trains continue to use one track through the tube.
There is a major delay system wide due to an equipment problem on the track in the Transbay Tube. There is no Red or Green Line service at this time. Trains are using one track and there is limited service through the Transbay Tube.
