Project Title:

Review of Department of Transportation Testing of Electronically Controlled Pneumatic Brakes
PIN: TRB-SASP-16-01        

Major Unit:

Transportation Research Board

Sub Unit: Studies and Special Programs Division

RSO: Wassel, Ray

Subject/Focus Area: Transportation and Infrastructure


Project Scope
In the first phase of this project, an ad hoc committee will review a test and analysis plan prepared by US Department of Transportation (DOT) and comment in a letter report on whether the proposed tests will provide objective, accurate, and reliable results to test the assumptions that US DOT has identified in its comparison of the emergency braking performance of railroad tank car Electronically Controlled Pneumatic (ECP) brakes to conventional brakes or braking systems such as distributed power and two-way end of train devices. The committee will provide a written explanation detailing the need for any additional or alternative testing. The key question is whether ECP brakes would reduce the incidence and severity of spills of crude oil or ethanol from derailments compared with the alternative braking systems examined.

In the second phase of this project, the committee will review the conduct of DOT's tests, reports of test results, and, based on DOT's test results and analysis, provide its findings and conclusions addressing the performance of ECP brakes relative to other braking technologies or systems tested by DOT. The committee's reviews and letter reports will be limited to these tasks; the committee will not make recommendations about which braking systems should be required of railroads in revenue service.
