DEPARTMENT OF TRANSPORTATION
Federal Railroad Administration Docket Number FRA20210091

Petition for Waiver of Compliance This document provides the public notice that on September 7, 2021, Wisconsin Central Ltd. WCL and Canadian National Railway Company collectively referred to as CN
petitioned the Federal Railroad Administration FRA under 49 CFR
211.51 to temporarily suspend for testing purposes, certain provisions of the Federal railroad safety regulations contained at 49 CFR 232.205, Class I
brake test-initial terminal inspection.
Although CN filed its petition under 211.51, FRA concluded that considering this request under the provisions of 49 CFR part 211, subpart C, Waivers, would be more appropriate.
Accordingly, FRA assigned the petition Docket Number FRA20210091.
Specifically, CN seeks relief from the requirements of 232.205ciiB for testing purposes which would allow CN
to operate trains with a combined air flow to the brake pipe above 90 cubic feet per minute CFM with no individual source of air having a flow greater than 60 CFM or 15 psi gradient.
CN seeks a short duration of relief to physically test braking reaction and train performance, under conditions of higher air flow, specifically caused by the addition of air sources air cars or locomotives that yield a more even pressure throughout the brake pipe. CN
seeks to perform the testing on the WCL
Chicago to Winnipeg corridor and the CN Sprague Subdivision, from November 2021 to April 2022, to test under cold temperature conditions. CN
has previously conducted similar testing through an exemption granted by Transport Canada between February and April 2020 and November 2020 and March 2021. CN reports that the program yielded positive results, demonstrating that when multiple air sources were used, trains operated at a healthy pressure level in cold weather, which resulted in cars applying an even level of braking effort and greater braking efficiency.
A copy of the petition, as well as any written communications concerning the petition, is available for review online at www.regulations.gov.
Interested parties are invited to participate in these proceedings by submitting written views, data, or comments. FRA does not anticipate scheduling a public hearing in connection with these proceedings since the facts do not appear to warrant a
