The American Association of Railroads submitted a petition to the FRA requesting an extension and expansion on two of its current waivers of compliance.
The first waiver allowed them to operate trains at class 5 speeds over heavy point frogs (HPF) with guard check gages conforming to the standards for class 4 track frogs.
AAR was also granted a waiver of compliance regarding frog guard rails and guard faces; gage that allowed them to operate trains at class 6 speeds over HPF designs with guard-check gages conforming to the standards for class 4 track frog guard check and face gage dimensions.
The current waivers are both due to expire on January 18, 2018. Interested parties may submit comments on either waiver request until October 6, 2017.
