Bay Area Rapid Transit is reporting major delays on two lines Thursday morning due to an equipment issue on the Peninsula.

Shortly after 8:40 a.m., the agency announced an equipment problem on the track near San Bruno led to a major delay on the SFO line in the Antioch, Richmond, SFO and Millbrae directions.

Several minutes later, BART said Red Line service between Richmond and Daly City was limited, along with Yellow Line service between Antioch and Colma. 

Around 9:40 a.m., no train service was running from San Francisco International Airport and San Bruno. A shuttle train was running between Colma and San Bruno and another shuttle train was running between SFO and Millbrae.

The agency did not provide an estimate on when the issue would be resolved.
