Petition for Modification of Single Car Air Brake Test Procedures

Under part 232 of Title 49 Code of Federal Regulations (CFR), this provides the public notice that on January 5, 2018, the Association of American Railroads (AAR) requested the Federal Railroad Administration (FRA) grant a modification of the single car air brake test procedures as prescribed in 49 CFR 232.305(a). FRA assigned the request Docket Number FRA-2018-0011.

As described in its request, the AAR Braking Systems Committee has revised and sent out for comment an updated version of AAR Standard S-486-04—Code of Air Brake System Tests for Freight Equipment, which is incorporated by reference in 49 CFR 232.305—Single car air brake tests. The main objective of the revision was to incorporate tests for a new feature known as brake cylinder maintaining. AAR asked for expedited processing of this request so the 60-day review period required by 49 CFR 232.307 can begin as soon as possible and the new procedure can be referenced in the CFR.

A copy of these documents and the petition, as well as any written communications concerning the petition, is available for review online at www.regulations.gov and in person at the U.S. Department of Transportation's (DOT) Docket Operations Facility, 1200 New Jersey Avenue SE, W12-140, Washington, DC 20590.
