Positive Train Control Systems (RRR)

Final rule.

FRA amends the regulations implementing a provision of the Rail Safety Improvement Act of 2008 that requires certain passenger and freight railroads to install positive train control (PTC) systems. This final rule removes regulatory provisions that require railroads to either conduct further analyses or meet certain risk-based criteria in order to avoid PTC system implementation on track segments that do not transport poison- or toxic-by-inhalation hazardous (PIH) materials traffic and are not used for intercity or commuter rail passenger transportation as of December 31, 2015.
