NTSB cites track circuit failure and WMATA’s lack of safety culture
The National Transportation
Safety Board determined that last year’s fatal collision of two Washington
Metropolitan Area Transit Authority trains on the Red Line in
Washington, D.C., was a failure of the track circuit modules that caused the
automatic train control system to lose detection of one train, allowing a
second train to strike it from the rear. The NTSB also cited WMATA for its
failure to ensure that a verification test developed after a 2005 incident near
Rosslyn station was used system-wide. This test would have identified the
faulty track circuit before the accident.
