BILLING CODE 4910-06-P DEPARTMENT OF TRANSPORTATION Federal Railroad Administration [Docket Number FRA-2012-0041] 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 April 4, 2012, the Metropolitan Transportation Authority Metro-North Commuter Railroad

(MNCW)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-2012-0041. MNCW seeks relief from the 2-year periodic testing requirements of the rules, standards, and instructions found at 49 CFR Sections 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. MNCW proposes to verify and test signal locking systems controlled by microprocessor-based equipment by use of alternative procedures every 4 years after initial baseline testing or program change as follows: • Verify the cyclic redundancy check/checksum/universal control number of the existing location's specific application logic to the previously tested version that is maintained in MNCW's Software Management Control Plan per requirements of 49 CFR 236.18. • Test associated hardware connections outside the processor to verify that inputs from switch indication, searchlight signal (where provided), track indication, or other vital inputs to the processor yield the intended output to switches or other devices intended to be locked in the field. • Analyze and compare results of each 4-year alternative test with the results of the baseline testing performed at the location, and submit results to FRA. MNCW submitted a list with their petition of 28 signal locations currently in service and subject to the relief being requested. 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
