  19 Appendix C Disclosure of Conflict(s) of Interest The conflict-of-interest policy of the National Academies of Sciences, Engineering, and Medicine (www.nationalacademies.org/coi) prohibits the appointment of an individual to a committee like the one that authored this Consensus Study Report if the individual has a conflict of interest that is relevant to the task to be performed. An exception to this prohibition is permitted only if the National Academies deter- mine that the conflict is unavoidable and the conflict is promptly and publicly disclosed. When the committee that authored this report was established a determination of whether there was a conflict of interest was made for each committee member given the individual’s circumstances and the task being undertaken by the committee. A determination that an individual has a conflict of interest is not an assessment of that individual’s actual behavior or character or ability to act objectively despite the con- flicting interest. Mr. Gerhard Thelen was determined to have a conflict of interest because he has a financial interest in the railroad industry. The National Academies determined that the experience and expertise of the individual was needed for the committee to accomplish the task for which it was established. The National Academies could not find another available individual with the equivalent experience and expertise who did not have a conflict of interest. Therefore, the National Academies concluded that the conflict was unavoidable and publicly disclosed it through the National Academies Current Projects System (www8.nationalacademies.org/cp).

TRB's Committee on the Review of the Department of Transportation's (DOT) Testing of Electronically Controlled Pneumatic (ECP) Brakes has issued its final letter report. In response to a Congressional request, the committee reviews the conduct of DOT's tests, reports of test results, and analysis comparing the performance of ECP brakes relative to other braking technologies in reducing the incidence and severity of spills of crude oil or ethanol from derailments.

The committee's report reviewing DOT's test and analysis plan, issued in February 2017, recommends that DOT test the timing of brake propagation for alternative systems, conduct statistical analyses of the multiple factors contributing to derailments, and extend its validation of its modeling and simulation approaches for comparing ECP brakes to other brake systems. The committee’s letter report reviewing the results of DOT’s testing and analysis, issued in September 2017, finds that DOT’s efforts to validate its model and simulation approaches are incomplete and unconvincing. Based on the results of testing and analysis provided by DOT, the committee is unable to make a conclusive statement about the emergency performance of ECP brakes relative to other braking systems.
