Electronically Controlled Pneumatic Brake Systems

Notice of proposed rulemaking (NPRM).

FRA proposes revisions to the regulations governing freight power brakes and equipment by adding a new subpart addressing electronically controlled pneumatic (ECP) brake systems. The proposed regulations are designed to provide for and encourage the safe implementation and use of ECP brake system technologies. The proposal contains specific requirements relating to design, interoperability, training, inspection, testing, handling defective equipment, and periodic maintenance related to ECP brake systems. The document also identifies provisions of the existing regulations and statutes where FRA is proposing to provide flexibility to facilitate the introduction of this advanced brake system technology.
