An aggressive effort to overhaul the aging Metro system in Washington, D.C., is producing results as it nears the one-year mark, with more than 28,000 cross-ties and nearly two miles of grout pads now replaced.
A prolonged short circuit in the third-rail power system of Washington, D.C.’s Metrorail system has been determined to be the probable cause for a January 2015 electrical arcing and smoke incident that killed one passenger and injured dozens more, according to the National Transportation Safety Board (NTSB).
