The train was stuck on the subway’s Transbay for a little more than an hour between the Embarcadero and West Oakland stations after an electrical problem forced the transit agency to take down one of the tracks, officials said Friday morning. The disabled train, which was heading to San Francisco, became stuck on the disabled track when the issue began shortly before 7:15 a.m. Friday. At 8:35 a.m., another train took it back to West Oakland, BART spokeswoman Cheryl Stalter said, where everyone had disembarked at the station. As of Friday afternoon, BART was still operating only one track for the Yellow and Blue lines through the tube and was still experiencing long delays, BART spokesman Jim Allison said. The Red and Green lines through the tube were canceled for the day. Alison added that the situation is not expected to change anytime soon. A service advisory on Friday morning encouraged people to “seek alternative forms of transport”. It was the second time in less than a week that equipment problems on the tube have disrupted service. On Sunday, service was restored after about two hours. Officials did not say what caused the problem at the time. The issues arose as the transit service tries to celebrate its 50th anniversary while facing the biggest drop in ridership in five decades of operation due to the pandemic, which has thrown its financial future into doubt.
