Start Preamble

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

The Union Pacific Railroad seeks relief from the requirements of the Rules, Standards and Instructions, Title 49 CFR Part 236, Section 236.377 Approach Locking, 236.378 Time Locking, 236.379 Route Locking, 236.380 Indication Locking and 236.381 Traffic Locking, regarding performance of locking test at intervals not to exceed 2 years, on processor-based systems to the extent that only the following be required 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 appropriate interconnection to signaling hardware and equipment outside of the processor (switch indication, track circuits and indications, searchlight Start Printed Page 67951and color-light signal indications, approach locking (if external) to verify correct and intended inputs and outputs from the processor are maintained.

Alternative locking test descriptions and procedures would be documented in Carriers Signal Maintenance Standards.

Applicant's justification for relief: The 2-year 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 once installed does not change.
