A Review of the Department of Transportation Plan for Analyzing and Testing Electronically Controlled Pneumatic Brakes: Letter Report

The Transportation Research Board's Committee on the Review of Department of Transportation (DOT) Testing of Electronically Controlled Pneumatic (ECP) Brakes has prepared a letter report reviewing U.S. Department of Transportation's (DOT’s) plan to evaluate the emergency performance of ECP brakes with other braking systems. Congress directed DOT to reconsider the ECP braking requirement for certain trains carrying high-hazard flammable liquids. The report recommends improvements to ensure that DOT's plan will lead to objective, accurate, and reliable tests of key assumptions the department made in comparing ECP emergency braking performance to other braking systems in reducing the incidence and severity of spills of crude oil or ethanol from derailments. In the second phase of this project, which will be carried out in 2017, the committee will review the conduct of DOT's tests and the reports of test results, and it will provide findings and conclusions on the performance of ECP brakes relative to other braking systems tested by DOT.
