Reports of smoke forced the closures and evacuations of three Metro stations Thursday afternoon, according to a spokeswoman for the transit agency.
Metro said on the platform X that the Eastern Market, Capitol South and Potomac Avenue stations closed about 1 p.m. because of smoke. Service was suspended on the Blue, Orange and Silver lines between the Federal Center SW and Stadium-Armory stations. Shuttle buses had been requested.
Fire officials said the source of the smoke was an insulator that caught fire under a rail car in the Eastern Market station in the 700 block of Pennsylvania Avenue SE. Metro said in a statement issued later that a preliminary investigation revealed arcing from a third-rail “shoe” that links power to rail cars.
