Positive Train Control Systems

Notice of public hearing and extension of comment period.

On August 24, 2011, FRA published a notice of proposed rulemaking that would remove regulatory provisions requiring railroads to either conduct further analyses or meet certain risk-based criteria in order to avoid positive train control (PTC) system implementation on track segments that do not transport poison- or toxic-by-inhalation (PIH) hazardous materials traffic and are not used for intercity or commuter rail passenger transportation as of December 31, 2015. FRA is announcing a public hearing to provide interested persons an opportunity to provide comments on the proposal and to discuss further development of the regulation. The Rail Safety Improvement Act of 2008 requires the implementation of PTC systems. FRA is also extending the comment period for this proceeding to allow time for interested parties to submit comments after the public hearing.
