Metro's general manager to announce maintenance plan

Metro's general manager is set to announce how he'll address systemic maintenance shortcomings on Washington's beleaguered subway system.

Paul Wiedefeld will detail his plan Friday at a news conference, a day after an arcing insulator forced the closure of a station for repairs.

Wiedefeld last month made an unprecedented decision to close the system for a day for emergency inspections and repairs of third-rail power cables. Several recent fires on the tracks have been blamed, in part, on faulty or poorly maintained power cables. Earlier this week, the National Transportation Safety Board blamed Metro's shoddy maintenance for a fire in January 2015 that killed a passenger and sickened dozens more.

Wiedefeld has said partial closures of the system will be necessary to return it to a state of good repair.
