Good afternoon Chairman Lynch, Ranking Member Chaffetz, and members of the Subcommittee.
On July 27, the National Transportation Safety Board (NTSB) held a Board Meeting to consider a report on the deadly June 22, 2009 collision of two Metrorail trains on the Red Line near the Fort Totten station. The Board adopted a report with 23 recommendations that, if implemented, will improve safety for Metro riders and transit riders throughout the country. I appreciate your holding this hearing today to examine these recommendations.
The accident resulted in nine fatalities, including the train operator, and emergency response agencies reported transporting 52 people injured in the accident to local hospitals. What NTSB investigators found, and the report concluded, was that the collision resulted from a failure of the track circuit modules, which caused the automatic train control (ATC) system to lose detection of one train, allowing a second train to strike it from the rear. The NTSB also concluded that the Washington Metropolitan Area Transit Authority (WMATA) failed to ensure that a verification test for track circuits, developed after a 2005 incident involving two near-collisions near the Rosslyn station, was used system wide. This test would have identified the faulty track circuit before the accident.
Beyond faulty track circuits, the NTSB’s investigation also revealed layers of safety deficiencies and a systemic breakdown of safety management at all levels. The NTSB concluded that the following factors also contributed to the accident: the lack of a safety culture within WMATA; WMATA’s failure to effectively maintain and monitor the performance of its automatic train control system; GRS/Alstom Signaling Inc.’s failure to provide a maintenance plan to detect spurious signals that could cause its track circuit modules to malfunction; ineffective safety oversight by the WMATA Board of Directors; the Tri-State Oversight Committee’s (TOC) ineffective oversight and lack of safety oversight authority; and the Federal Transit Administration’s (FTA) lack of statutory authority to provide federal safety oversight. The NTSB report also cited that WMATA’s failure to replace or retrofit the 1000-series cars contributed to the severity of passenger injuries and the number of fatalities, after these cars were shown in previous accidents to exhibit poor crashworthiness.
As a result of this investigation, the NTSB made 23 recommendations to the U.S. Department of Transportation, the FTA, TOC, WMATA, Alstom Signaling, and transit authorities in six states that use GRS Generation 2 modules. The NTSB approved recommendations are attached to my testimony.
After the Board Meeting
Two weeks after adopting the report, an unprecedented meeting between the five NTSB Board members and the entire WMATA Board of Directors took place at Metro headquarters to discuss the NTSB report’s findings and recommendations. In that meeting Interim General Manager Richard Sarles discussed the NTSB recommendations and the steps WMATA would take to address the recommendations. WMATA is taking this report seriously, and WMATA officials have committed to implementing all NTSB recommendations.
In response to a Congressional inquiry, WMATA Board Chairman Peter Benjamin estimates the cost of implementing the recommendations at $935 million. The largest portion of this expense is the replacement of the 1000-series cars at $835 million. (In fact, WMATA has already ordered 428 next generation of cars which will start arriving in 2013.) While rail cars with improved crashworthiness standards are very important, they are the last line of defense. Implementing the less costly recommendations can lead to a safer overall system with a focus on accident prevention.
I am hopeful that WMATA can create and promote a strong safety culture. Just last week, the WMATA Board of Directors proposed a new mission statement, which, if adopted, will include “safety,” and they created the new Safety and Security Committee, comprised of the entire Board of Directors, focused primarily on safety. This action demonstrates that the WMATA Board is embracing the idea that safety must be promoted at the top levels of an organization to ensure that all employees recognize its importance. My colleagues and I view these actions as a significant step forward in improving safety.
The Board will continue to work with WMATA to create and promote a strong and effective safety culture and implement the additional safety recommendations. If WMATA continues along this path it can regain the trust of its ridership, and re-emerge as a leader in the public transportation industry.
Thank you for inviting me to appear before you today. This concludes my remarks, and I am available to answer your questions.
