NTSB PRESS RELEASE ************************************************************ National
Transportation Safety Board Washington,
DC 20594 FOR
IMMEDIATE RELEASE: July 27, 2010 SB-10-29 ************************************************************ NTSB
CITES TRACK CIRCUIT FAILURE AND WMATA'S LACK OF A SAFETY
CULTURE IN 2009 FATAL COLLISION ************************************************************ The
National Transportation Safety Board today determined that
last year's fatal collision of two Washington Metropolitan
Area Transit Authority (WMATA) trains on the Red
Line in Washington, D.C., was a failure of the track circuit
modules that 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 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. Contributing
to the accident was the lack of a safety culture
within WMATA; ineffective safety oversight by the WMATA
Board of Directors and the Tri-State Oversight Committee
(TOC); and the Federal Transit Administration's (FTA)
lack of statutory authority to provide federal safety oversight.
Additionally, WMATA's failure to replace or retrofit
the 1000-series rail cars, after these cars were shown
in previous accidents to exhibit poor crashworthiness, contributed
to the severity of passenger injuries and the number
of fatalities. On
June 22, 2009, at approximately 5 p.m., train 112 struck the
rear of stopped train 214 near the Fort Totten station in
Washington, D.C. The lead car of train 112 struck the rear
car of train 214, causing the rear car of train 214 to telescope
about 63 feet into the lead car of train 112. Nine people
aboard train 112 were killed as a result of the accident,
including the train operator, and dozens were injured. "The
layers of safety deficiencies uncovered during the course
of this investigation are troubling and reveal a systemic
breakdown of safety management at all levels," said Chairman
Deborah A.P. Hersman. "Our hope is that the lessons learned
from this accident will be not only a catalyst for change
at WMATA, but also the cornerstone of a greater effort
to establish a federal role in oversight and safety standards
for rail transit systems across the nation." As
a result of this investigation, the NTSB made recommendations
to the U.S. Department of Transportation, the
FTA, TOC, WMATA, Alstom Signaling and transit authorities
in six states using GRS Generation 2 modules. Issue
areas included safety oversight, equipment inspection and
maintenance guidelines and procedures, and targeted equipment
removal and replacement. A
synopsis of the NTSB report, including the probable cause, conclusions
and safety recommendations, is available on the NTSB
website. The
NTSB's full report will be available on the website in several
weeks. #
