In 2005, 14 percent of train accidents on mainline track caused by human error involved the improper handling or misuse of the automatic braking system. Today’s air-brake systems are built on 19th century pneumatic technology that has been progressively refined to support current railroad operations. Broad agreement exists among railroads, suppliers, and users of these systems that they have serious limitations that cannot be remedied with further incremental changes.

The FRA intends to propose revised Federal rail safety regulations to facilitate the installation of Electronically Controlled Pneumatic (ECP) brake systems capable of preventing derailments and shortening train stopping distances. Toward this end, FRA is releasing the Booz Allen Hamilton final report, “ECP Brake System for Freight Service.” The study addresses the issues surrounding this technology, presents alternative plans for ECP brake implementation, and offers a recommended approach.
