## Abstract

FRA is amending its Safety Glazing Standards for exterior windows on railroad equipment to codify long-standing waivers, add a new testing option to improve consistency of glazing testing, and revise outdated section headings. The changes update and clarify existing requirements to maintain and, in some cases, enhance safety, while reducing unnecessary costs. Codification of the waivers is also consistent with the Infrastructure Investment and Jobs Act and will enable FRA to use its inspection resources more efficiently.
