WASHINGTON (AP) - Washington subway officials say they have suspended service on a section shared by three lines after smoke appeared in a station.
Metro tweeted that the service was suspended Thursday afternoon from Eastern Market to Federal Center SW.
That section serves the orange, blue and silver lines, and includes the Capitol South station, which is also closed.
Metrobus shuttles are running between the stations.

Metro tweeted that the closure was necessary to replace the third-rail insulator at Federal Center. That's where the smoke was discovered.
District of Columbia fire department spokesman Doug Buchanan told The Washington Post that the insulator was arcing. He says the fire department received a report of a light haze of smoke in the station. Firefighters responded, then cleared the station about 5:30 p.m.
Metro Transit Police tweeted that there were no injuries.
