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 November 14, 2016, The Belt Railway Company of Chicago (BRC) 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-2016-0111.
BRC seeks relief from certain requirements of part 236; specifically 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. BRC 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:
- Verifying the Cyclic Redundancy Check (CRC)/Check Sum/Universal Control Number (UNC) of the existing location's specific application logic to the previously tested version.
- Testing the appropriate interconnection to the associated signaling hardware equipment outside of the processor (switch indication, track indication, searchlight signal indication, approach locking (if external)) to verify 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 and submit the results to the FRA.
Many of BRC's Interlockings, control points, and other locations are controlled by solid-state, vital microprocessor-based systems. These systems use programmed logic equations in lieu of relays or other mechanical components for control of both vital and non-vital functions. The logic does not change once a microprocessor-based system has been tested and locking tests are documented on installation.
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 Department of Transportation's (DOT) Docket Operations Facility, 1200 New Jersey Avenue SE., W12-140, Washington, DC 20590.
