BART system returning to normal after major morning delays

BART service was returning to normal after commuters Tuesday morning faced considerable delays from a disabled train blocking the Transbay Tube, switching problems and numerous medical emergencies, officials said.

Delays running more than 30 minutes began shortly before 7 a.m. when a Richmond-bound train broke down just outside the Transbay Tube, where trains cross from one track to another, said Jim Allison, a BART spokesman. The disabled train was pushed out of the way by about 7:25 a.m., clearing the Transbay Tube.

Service was restored by about 10 a.m. with 10 minute delays.

The train was stuck on the Oakland side between the West Oakland and Embarcadero BART stations and was “blocking all traffic through the Transbay Tube,” Allison said.

Crews worked to move another train into position to push the disabled train to the 12th Street Oakland City Center station, Allison added.

Additionally, numerous of switching problems on various trains in the West Oakland area and several medical emergencies on different trains, none serious, contributed to the slowdown, officials said.
