Railroad Submits Petition for Reconsideration of July 25, 2008, Accident
Report
NORFOLK, Va., Aug. 29 /PRNewswire-FirstCall/ -- In a formal petition
filed today with the National Transportation Safety Board, Norfolk Southern
Railway Company presented documentation and analysis, including new
evidence, clearly establishing good cause for the NTSB to reexamine and
amend its conclusion regarding the cause of an Oct. 20, 2006, derailment in
New Brighton, Pa. The NTSB's assertion that the accident was caused by an
"inadequate rail inspection and maintenance program" is contrary to both
the new and previously available evidence provided to the agency during its
original investigation.
The immediate cause of the New Brighton accident was a rail fracture
that occurred when an eastbound freight train passed over the track. As a
result, 23 rail cars loaded with ethanol derailed, and many caught on fire.
There were no injuries to the train crew or public. Norfolk Southern's
response to the derailment, including addressing the needs of nearby
residents, was deemed appropriate by the NTSB.
The main focus of the NTSB's investigation was an Aug. 1, 2006,
ultrasonic rail inspection. The NTSB claims that one of the 24 ultrasonic
signals was interrupted and, as a result, a defect in the rail was not
discovered. The NTSB concludes that the rail defect would have been
discovered if the ultrasonic signal had not been interrupted.
Countering that conclusion, Norfolk Southern's rail inspection
contractor recently verified that the operator of the inspection vehicle,
having observed a possible defect on an adjacent rail, immediately
conducted a second ultrasonic test. This second test ensured that all 24
ultrasonic signals were being continuously sent. This data produced by the
operator's second test was provided to the NTSB after it announced its
determination of probable cause at a public meeting held on May 13, 2008,
but before the issuance of its July 25, 2008, Accident Report.
The defect that ultimately led to the derailment was not detected by
the ultrasonic test conducted nine weeks earlier, because despite the use
of the best technology available the defect either did not exist or was too
small to be detected.
"The NTSB's findings and recommendations should be based upon the
complete facts," said Tim Drake, Norfolk Southern's vice president
engineering. "Based on the uncontroverted, scientifically-proven evidence
Norfolk Southern has furnished, the NTSB lacks a factual basis to determine
that our track and maintenance program is inadequate, and we urge the Board
to correct its erroneous conclusions."
"We have provided irrefutable proof that the derailment was caused by a
defect that could not have been detected by the advanced technologies used
during the Aug. 1, 2006, track inspection," said Drake. "Norfolk Southern
has the lowest track-related accident rate among Class 1 railroads, and
even the NTSB has recognized that we inspect our track for internal defects
more frequently than required by the Federal Railroad Administration."
A copy of Norfolk Southern's Petition for Reconsideration and
Modification will be provided upon request.
