Metro spokeswoman Sherri Ly said the transit agency first received a report of a person on the tracks outside the Minnesota Avenue station on the Orange Line.
“The individual who appeared to possibly be under the influence was apprehended and removed from the roadway,” Ly said.
Service was restored just before 4:30 p.m., Metro said in a tweet.
The suspension included service to six Metro stops, including Eastern Market, Potomac Avenue, Stadium-Armory, Benning Road, Capitol Heights and Addison Road.
Shuttle buses were dispatched to the stations to pick up and drop off passengers to operating Metro stations, Ly said.
