The National Transportation Safety Board investigation into the cause of the Washington Metropolitan Area Transit Authority accident is still ongoing. It is very early in the investigation and there is still much work that needs to be done to make final determination of probable cause and any potential recommendations.
As the NTSB continues to gather information which will assist in determining the probable cause of Monday’s accident, investigators are also gathering information on the disruption to the power system, maintenance of the transit system, emergency response and evacuation. The DC Government’s report is only one part of the emergency response, and it will be examined with all the evidence in the context of the investigation.
It is important to note that, if the NTSB at any time finds that a particular safety issue needs to be addressed, the NTSB can and will issue an urgent safety recommendation if warranted before the completion of the final report. Additional information will be released as it becomes available.
