All San Francisco cable car services are closed until Friday after evacuation of facilities and a power failure

SAN FRANCISCO (CBS SF) – All cable car services in San Francisco were closed Thursday afternoon after SFMTA had to evacuate the cable car barn due to a smoke alarm, according to transit officials.

The SFMTA’s Twitter account posted about the service shutting down around 1:45 p.m. Thursday. Muni officials said shuttle buses would provide service to cover the Powell, Powerll-Hyde, Powell-Mason and California cable car lines.

Officials did not initially explain why the cable car barn had to be evacuated.

Transport officials later said a smoke alarm went off in the cable car barn, prompting the evacuation. But apparently it was a false alarm.

However, a power failure resulted in the shutdown of all cable car services. This failure was in progress.

UPDATE: Evacuation is now complete due to a previous smoke detector. All cable car lines will continue to be down due to a power outage. Bus shuttles providing the service. Will update. https://t.co/6vGnMj9Ihm

Earlier Thursday, shortly before 12:30 p.m., Muni officials tweeted about another service shutdown affecting the California cable car line.

ATTN: California Cable Car Line delayed in both directions due to cable shutdown. The teams on site are working to resolve. Will update.

SFMTA officials did not say whether the previous shutdown was related to the evacuation of the cable car.

This is breaking news. CBS SF will provide further details as they become available.
