The Bethesda Metro station is closed for the second time on Wednesday, this time due to a power outage.

Metro announced the outage on Twitter at 7:16 p.m. Trains are skipping the station, and buses will soon be available to take passengers from Medical Center, the next stop to the north, the tweets said.

Metro Transit Police described the outage on Twitter as “a total power outage affecting all station lighting & equipment.” Spokesman Mike Tolbert said that the cause hasn’t been determined yet, but might be a circuit breaker on the main switchboard that serves the station.

During the morning hours on Wednesday, the station also shut down temporarily. Tolbert said the two closures were unrelated.

The station had a better day on Monday, when a brand-new — and very long — escalator opened.

But by Wednesday, that brand-new escalator was causing problems. Tolbert said that a safety trigger on the new escalator tripped, shutting it down and causing Metro to close the station.
