Conduct an engineering simulation of predicted HEP car collision performance and provide to Transport Canada a report summarizing the assumptions and findings by October 31, 2022.
Conduct a tear down inspection of four HEP cars with structural defects to identify whether additional structural conditions, which are only visible in this invasive-type inspection, are present and provide Transport Canada with a copy of the inspection report and a list of recommended actions by January 31, 2023.
Conduct a static structural test (compression test) to the requirements of the Association of American Railroads - S034, of at least two unrepaired HEP cars, to validate the structural capacity and provide Transport Canada a copy of the test report and an assessment of how the test outcomes will inform future repairs and mitigating measures by January 31, 2023.
Provide the final report of the engineering simulation, incorporating findings from tear down and static structural tests required in item 3 and item 4 by March 31, 2023.
Conduct a static structural test (compression test) to the requirements in the Association of American Railroads - S034, of at least one fully repaired HEP car, to validate the repair methodology and provide TC a copy of the test report and an assessment of how test outcomes will inform future repairs and mitigating measures by December 31, 2023
So they need to crash them, determine how to fix them to be stronger, test them and present it within 2 months. I would think that they are closer to figuring out how to fix them at this point. But then again once they understand the weaknesses, computer modelling can tell you what to fix.
