In accordance with part 211 of Title 49 of the Code of Federal Regulations (CFR), this document provides the public notice that by a document dated December 2, 2011, Northeast Illinois Regional Commuter Railroad Corporation (Metra) has petitioned the Federal Railroad Administration (FRA) for a waiver of compliance from certain provisions of the Federal railroad safety regulations contained at 49 CFR part 236. FRA assigned the petition Docket Number FRA-2011-0101.
Metra seeks relief from the 2-year periodic testing requirements of the Rules, Standards and Instructions, 49 CFR 236.377, Approach Locking; 236.378, Time Locking; 236.379, Route Locking; 236.380, Indication Locking; and 236.381, Traffic Locking; on vital microprocessor-based systems. Metra proposes to verify and test signal locking systems controlled by micro-processor-based equipment, by use of alternative procedures, every 4 years after initial baseline testing or program change as follows:
- Verifying the cyclic redundancy check/checksum/universal control number of the existing location's specific application logic to the previously tested version.
- Testing the appropriate interconnection to the associated signaling hardware equipment outside the processor (switch indication, track indication, searchlight signal indication, approach locking—if external) to verify the correct and intended inputs to and outputs from the processor are maintained.
- Analyze and compare the results of the 4 year alternative testing with the results of the baseline testing performed at the location then submit the results to FRA.
Metra submitted a list with its petition of each signal location at which Metra intends to implement these alternative procedures.
A copy of the petition, as well as any written communications concerning the petition, is available for review online at www.regulations.gov and in person at the U.S. Department of Transportation's (DOT) Docket Operations Facility, 1200 New Jersey Avenue SE., W12-140, Washington, DC 20590.
