Federal Railroad Administration

[Docket Number FRA-2012-0023]


Petition for Waiver of Compliance

    In accordance with Part 211 of Title 49 Code of Federal Regulations 
(CFR), this document provides the public notice that by a document 
dated January 25, 2012, Union Pacific Railroad (UP) has petitioned the 
Federal Railroad Administration (FRA) for a permanent waiver of 
compliance from certain provisions of the Locomotive Safety Standards, 
found at 49 CFR 229.129(b) and (c), and which pertain to railroad 
locomotive horn testing. FRA assigned the petition Docket Number FRA-
2012-0023.
    UP seeks to use an automated sound measurement system (ASMS) to 
test locomotive horns as required in 49 CFR 229.129(b). The ASMS uses a 
Class 1 sound-level measuring instrument that is permanently mounted in 
a fixed test site and uses the same technology that is used to measure 
noise at airports nationwide. Due to the proven accuracy and 
reliability of the ASMS and the tight procedural control and concise 
documentation they provide (plus the fact that the frequency and 
duration of horn blasts and the resulting impact on the surrounding 
community and personnel is reduced), UP strongly believes that the ASMS 
is an improvement from the current testing scheme permitted under 49 
CFR 229.129.
    In addition, UP requests a waiver to extend the duration between 
acoustic calibrations (49 CFR 229.129(c)(9)) from immediately before 
and after each session of compliance tests, or no later than 8 hours, 
as clarified in 71 FR 47626, to a period of no more than 6 months.

    UP also requests FRA approval of all locomotive horn test data 
acquired by any of UP's ASMS that meet the requirements of SAE ARP-4 
721, and have been calibrated in accordance with this waiver.
