Federal Railroad Administration January 28, 2013 – Federal Register Recent Federal Regulation Documents

In response to a petition for rulemaking, FRA proposed, in a notice of proposed rulemaking (NPRM) dated December 11, 2012, 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 present document clarifies FRA's responses to several elements of the Association of American Railroads' (AAR) petition for rulemaking and which elements of the petition for rulemaking FRA is considering, and asks specific questions concerning those elements. This document does not alter FRA's proposal as issued December 11, 2012, but it does extend the comment period in this proceeding to March 11, 2013.
