NTSB Issues Urgent Safety Recommendations to WMATA

Wednesday, September 23, 2009

As a result of The National Transportation Safety Board (NTSB) ongoing investigation into the collision between two Washington Metropolitan Area Transit Authority (WMATA) trains in June 2009, NTSB issued nine safety recommendations, six of which are urgent, to address concerns about the safety of train control systems that use audio frequency track circuits.


NTSB makes specific recommendations and calls upon WMATA to develop a program to periodically determine that the electronic components in its train control systems are performing within design tolerances.
