Board member Robert Sumwalt told a House subcommittee Wednesday that the
cars, known as DOT-111s, were involved in derailments of oil trains in
Casselton, N.D., and Lac-Megantic, Quebec, just across the U.S. border.
The NTSB has long urged replacement of the tank cars, but federal efforts to write tougher regulations for new tank cars have dragged on for two years.
Cynthia Quarterman, head of the federal hazards materials safety administration, said she expects to propose new rules this year. She had no estimate for when the rule would be final.
