Train Braking: DOT's Rulemaking on Electronically Controlled Pneumatic Brakes Could Benefit from Additional Data and Transparency, Report to Congressional Committees   [open pdf - 2MB]

"In May 2015, DOT issued a final rule requiring certain trains hauling flammable liquids to equip with ECP [Electronically Controlled Pneumatic] brakes. This rule has met opposition from many industry stakeholders. The Fixing America's Surface Transportation Act requires DOT [Department of Transportation] to test ECP brakes and reevaluate the economic analysis supporting the ECP brake requirement and includes a provision for GAO [Government Accountability Office] to review the potential costs and benefits of ECP. This report examines views on costs railroads may realize in meeting the ECP brake rule, the potential business benefits, and how DOT and the railroad industry estimated safety benefits. GAO reviewed rulemaking documents; interviewed 13 rail experts selected based on published work and suggestions from the National Academies of Sciences; interviewed DOT officials and representatives of the seven largest railroads in North America; interviewed industry stakeholders, including the Association of American Railroads and compared DOT's estimates and modeling efforts against federal criteria and GAO standards for internal control."
