Metro trains are not stopping at the Bethesda station because one of the station’s escalators is not working.

Buses are taking passengers from the Medical Center station to and from Bethesda.

Metro said the outage is linked to the power outage that knocked out power in much of Washington and parts of Maryland earlier in the afternoon. That outage affected 13 Metro stations, but Bethesda was not one of them. And the Bethesda escalator did not stop working until about 3:15 p.m., more than two hours after the wider power outage began.

The Bethesda station has to close whenever one of its escalators malfunctions, Stessel said. One of its three escalators is blocked off for a long-term repair. The station can operate with two escalators on a daily basis, but operating with just one would be unsafe, Metro spokesman Dan Stessel said.

Repairs were expected to be finished early Tuesday evening.
