[Description] In 2005, SAFETEA-LU required FRA to conduct a comprehensive analysis to determine the impact resistance of the steels in the shells of pressurized tank cars constructed prior to 1989. To address this SAFETEA-LU requirement and NTSB's recommendation, the Southwest Research Institute (a subcontractor to FRA's contractor, the Volpe Center) has produced a final research report on its work in basic material characterization, tensile property evaluation, chemical makeup, and sharpy v-notch toughness at three different temperatures of the steels in the shells and heads of pre-1989 tank cars.
