Notice of proposed rulemaking.
Summary
FRA proposes amendments to regulations implementing a requirement of the Rail Safety Improvement Act of 2008 that certain passenger and freight railroads install positive train control (PTC) systems. The proposal would revise the regulatory provisions related to the de minimis exception to the installation of PTC systems generally, and more specifically, its application to yard-related movements. The proposal would also revise the existing regulations related to en route failures of a PTC system and discontinuances of signal systems once a PTC system is installed and make additional technical amendments to regulations governing grade crossing warning systems and signal systems, including PTC systems.
