The Federal Center SW Metro station has been evacuated and temporarily closed due to a report of smoke inside the station. WMATA has established shuttle bus service around the closure. The smoke is believed to have been caused by a burned-out lighting fixture near the station platform. No injuries have been reported, but D.C. Fire/EMS is still on the scene investigating. Stay tuned. UPDATE 2:30 p.m. WMATA reports the station has re-opened.
