Metro shut down for a full-day for an emergency safety inspection of its third-rail power cables. The Federal Transit Administration has announced a safety inspection blitz of its own focusing on rail yard safety, red light signals and track integrity. The FTA says that Metro has not adequately assessed the root cause of an August derailment outside of the Smithsonian Station. And that the McPherson Square fire was a symptom of what the agency called "poor preventative maintenance." (AP Photo/Pablo Martinez Monsivais)
