The Federal Railroad Administration (FRA) published a notice (78FR 5767-5770) in Monday’s Federal Register (available on line yesterday) that extended the deadline for comments on their notice of proposed rulemaking (NPRM) published in December 2012 that makes changes to the current positive train control (PTC) system requirements. The new deadline for comments is now March 11, 2013.
The notice specifically clarifies some railroad operational questions that it wishes additional comments upon, but any comments on the NPRM will be accepted during the comment extension.
The NPRM would allow railroads to request that certain miles of track be removed from the requirement for the installation or maintenance of a PTC system under relatively low usage rates for carrying toxic inhalation hazard (TIH) chemicals. This could lower railroad costs for handling TIH chemical on those track segments.
