Update 3:35: Looks like those track problems are still a problem. BART is reporting 10 to 15-minute delays across the whole system due to equipment problems on the track near West Oakland Station.
Original Story 9:34 a.m..: BART is reporting mega delays systemwide, thanks to a track problem in the Transbay Tube.
The delays are the worst between West Oakland and Embarcadero, but no BART rider is being left out of this misery. The whole system is backed up in this morning congestion, says Alicia Trost, spokeswoman for BART
"We do have crews that just arrived on scene," she says. Until the problem -- whatever it is -- is fixed, trains are having to run on manual mode, which is causing the slowdown.
A limited number of trains are able to travel through the Transbay Tube at this time.
