          - [Docket Number FRA-2005-21179]

Under part 211 of title 49 Code of Federal Regulations (CFR), this document provides the public notice that on December 3, 2020, Union Pacific Railroad Company (UPRR) petitioned the Federal Railroad Administration (FRA) for an extension of a waiver of compliance from certain provisions of the Federal railroad safety regulations contained at 49 CFR part 229, Railroad Locomotive Safety Standards, and part 232, Brake System Safety Standards for Freight and Other Non-Passenger Trains and Equipment; End-Of-Train Devices. FRA assigned the petition Docket Number FRA-2005-21179.

                    Specifically, UPRR requests to extend its relief from 49 CFR 229.49,                     *Main reservoir systems,*                     and 49 CFR 232.103,                     *General Requirements for All Train Brake Systems,*                     for locomotives having a safety valve on the main reservoir, which prevents accumulation of more than 25 psi above maximum working pressure. UPRR states it has been operating under the requirements set forth in this waiver for 15 years and has found no adverse effect on the safety of operations.                

                    A copy of the petition, as well as any written communications concerning the petition, is available for review online at                     *www.regulations.gov.*
