(WASHINGTON) -- Two "smoke incidents" at the Federal Center metro station in Washington, D.C., on Thursday prompted the transit authority to order the temporary closure of the station, a metro official told ABC News.
Surveillance video shows what looks like an explosion erupting on the tracks moments after a train passes, apparently due to an arcing insulator.
There were no injuries, but after a second incident Thursday evening, Washington Metropolitan Area Transit Authority General Manager Paul Wiedefeld, in consultation with the Department of Transportation and Federal Transit Administration, decided crews would replace "every insulator in the station," according to a metro official.
Federal Center was re-opened Friday, and full service was restored on the orange, blue and silver lines.
