Federal Railroad Administration

 
Petition for Waiver of Compliance

    In accordance with Part 211 of Title 49 Code of Federal Regulations 
(CFR), notice is hereby given that the Federal Railroad Administration 
(FRA) has received a request for a waiver of compliance from 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 from the requirements of 
Title 49 CFR Part 236, as detailed below.

Union Pacific Railroad Company

[Docket Number FRA-2009-0117]

    The Union Pacific Railroad (UP) seeks relief from the requirements 
of the Rules, Standards, and Instructions, Title 49 CFR Part 236. 
Specifically, UP seeks relief from the requirements of Subpart A, Rules 
and Instructions: All Systems, Section 236.109 Time releases, timing 
relays and timing devices; regarding performance of timing duration 
test on timers with variable settings at an interval of not less than 
once every 12 months. UP seeks to extend periodic testing requirements 
of non-adjustable timers from at least once every 12 months to every 4 
years after initial testing has been completed at all interlockings, 
control points, and other signal locations controlled by 
microprocessor-based equipment. This request for relief proposes to use 
alternative locking test procedures at signal locations with 
microprocessor-based equipment after an initial base line time duration 
test is performed. The following proposed alternative timer tests will 
be performed every 4 years after initial testing or program change:
     Verification of the Cyclic Redundancy Check/Check Sum/
Universal Control Number of the existing location specific application 
logic to the previously tested version (baseline testing).
     Testing the duration of any timers with variable settings.
    Alternative test descriptions and procedures for timers with 
variable settings in microprocessor-based equipment would be documented 
in Carriers Signal Maintenance Standards.
    Applicant's justification for relief: The requirement for not less 
than once every 12 months testing interval at microprocessor controlled 
signal locations places an unnecessary burden on the carrier and 
provides no real safety benefit as the application program logic (and 
timer values) once installed does not change.
    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 hearing. If any interested party

writing, before the end of the comment period and specify the basis for 
their request.
