"The Trump administration on Monday repealed a mandate that would have required trains carrying crude oil to use special brakes with new technology.

The Department of Transportation's Pipelines and Hazardous Materials Safety Administration (PHMSA) said it undertook a congressionally mandated analysis of the provision in a 2015 regulation under which oil trains would have had to use electronically controlled pneumatic (ECP) brakes.

“The Department [of Transportation] determined that the expected benefits, including safety benefits, of implementing ECP brake system requirements do not exceed the associated costs of equipping tank cars with ECP brake systems, and therefore are not economically justified,” PHMSA said."
