NTSB: Metro safety oversight is 'fundamentally flawed'

(AP) -- The chairman of the National Transportation Safety Board says Washington's subway system appears not to have made meaningful safety improvements since a fatal accident in 2009.

The board is meeting Tuesday to determine what caused a January 2015 fire inside a downtown tunnel that killed one passenger and injured dozens more.

NTSB investigators have found problems with the third-rail power cables and repeated water leaks at the site of the electrical malfunction that led to the fire.

The board made several recommendations to the Metro subway system after a 2009 crash that killed nine people. Board chairman Christopher Hart said Tuesday that "safety still is not institutionalized as a core value" at Metro. He says the problems that led to the 2015 fire "were allowed to develop and persist."
