Reflectorization of Rail Freight Rolling Stock; Codifying Existing Waivers

This rule amends the standards for Reflectorization of Rail Freight Rolling Stock (Reflectorization Standards or Part 224) to codify waivers and remove the outdated implementation schedule. The changes are expected to enhance safety, promote innovation, clarify existing requirements, and reduce unnecessary paperwork burdens. The amendments are consistent with the mandate of the Infrastructure Investment and Jobs Act (IIJA), which requires FRA to review and analyze certain longstanding waivers to determine whether incorporating the waivers into FRA's regulations is justified.
