          - [Waiver Petition Docket Number FRA-2004-18896]

In accordance with Part 211 of Title 49 Code of Federal Regulations (CFR), notice is hereby given that the Federal Railroad Administration (FRA) received a request for a waiver of compliance with certain requirements of its safety standards. The individual petition is described below, including the party seeking relief, the regulatory provisions involved, the nature of the relief being requested, and the petitioner's arguments in favor of relief.

## Union Pacific Railroad Company 

The Union Pacific Railroad Company (UPRR) seeks a waiver of compliance with the Locomotive Safety Standards, 49 CFR 229.49(a)(1) and with the Brake System Safety Standards 49 CFR 232.103(o)(2), as they pertain to main reservoir safety valve setting and minimal deferential between brake pipe and main reservoir air pressure on UPRR locomotives. The railroad states in their request that their locomotive safety valves are set at 150 (one hundred fifty) pounds-per-square-inch (psi) and the maximum working pressure of 125 psi (one hundred twenty-five) creating a 25 (twenty-five) psi differential. Locomotive safety standards (49 CFR 229.46(a)(1) requires that the main reservoir system of each locomotive shall be equipped with at least one safety valve that shall prevent an accumulation of pressure of more than 15 pounds per square inch above the maximum working air pressure and Brake System Safety Standards (49 CFR 232.103(o)(2)) requires minimum differential 15 psi between brake pipe and main reservoir air pressures, with brake valve in running position. UPRR adjusted its fleet of locomotives maximum working air pressure from 135 psi to125 psi in the late 1970's as a method to conserve fuel. The 150 psi safety valve setting was maintained so that UPRR locomotives remained compatible when operated in consist with foreign locomotives. UPRR has operated their locomotives with the 125 psi maximum working air pressure for over twenty-five years and reports no adverse effect.
