AAR Circular Letter Summary – May 2021
Circular letter summaries are produced monthly by Greenbrier’s Regulatory Management team, a division of Greenbrier Management Services Group. AAR circular letters provide information of general applicability to the railroad industry, including proposed and final rules, revisions, standards and recommended practices, and calls for comments. These summaries provide the main points of circular letters issued in the prior month, as well as important implementation deadlines.
