An ongoing BART service interruption between San Francisco and the East Bay has Monday morning commuters stranded and frustrated.

"BART service has stopped between West Oakland and Embarcadero due to downed power lines in the West Oakland area," explains a service advisory from the transit agency. "West Oakland Station is closed."

Tweets from the agency indicate service could be interrupted for up to two hours.

Update: Just after 9:30 a.m., Transbay BART service was restored according to the transit agency. Delays still pervade the system as it recovers from the interruption.

According to the the Chronicle, a car that crashed into a power pole sent electrified wires crashing onto BART tracks.

At around 9:20 a.m., the power lines were removed and tracks were being inspected.

The resulting electrical problems were the second issue of the morning, halting trains completely after they were delayed by a trespasser on tracks near San Leandro's Bay Fair Station.

The situation left travelers looking for other means of transit. AC Transit was honoring BART tickets, but Uber and Lyft prices were surging, and ferry lines were growing.

Even after the restoration of service was announced, some skeptical riders demanded proof.
