BILLING CODE 4910-06-P DEPARTMENT OF TRANSPORTATION Federal Railroad Administration [Docket Number FRA-2012-0042] 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 March 22, 2012, CSX Transportation

(CSX)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-2012-0042. CSX seeks relief from the requirements of 49 CFR Part 236, Rules, Standards, and Instructions Governing the Installation, Inspection, Maintenance, and Repair of Signal and Train Control Systems, Devices, and Appliances; and Section 236.109, Time releases, timing relays and timing devices. CSX requests relief from 49 CFR 236.109 as it applies to variable timers within the program logic of the operating software of microprocessor-based equipment. CSX states that timing devices contained within microprocessor-based equipment are typically nonvariables and are within the program logic of the operating software. However, CSX notes that some microprocessor-based equipment have variable timers. CSX is requesting relief from the requirement of checking the actual time interval of microprocessor-based variable timers. Such variable timers will use verification of the cyclic redundancy check/check sum/universal control number of the existing location specific application logic to the previously tested version. 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
