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.

[[Page 35108]]

    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
