Federal Railroad Administration

 
Petition for Waiver of Compliance

    In accordance with Part 211 of Title 49 Code of Federal Regulations 
(CFR), notice is hereby given that the Federal Railroad Administration 
(FRA) received a request for a waiver of compliance from certain 
requirements of its safety standards. The individual petition is 
described below, including the party seeking relief, the regulatory 
provisions involved, the nature of the relief being requested, and the 
petitioner's arguments in favor of relief.

Norfolk Southern Corporation

(Docket Number FRA-2008-0042)

    The Norfolk Southern Corporation (NS) seeks a waiver of compliance 
from certain provisions of 49 CFR Part 232, Brake System Safety 
Standards for Freight and Other Non-Passenger Trains and Equipment. 
Specifically, NS is requesting a temporary waiver from the requirement 
to display in real-time, in the cab of the locomotive, the total train 
dynamic brake retarding force available in the train, as prescribed in 
49 CFR 232.109(g)(2), on locomotives placed in service for the first 
time on or after October 1, 2007. The functionality of this requirement 
is commonly referred to as the ``Dynamic Brake Status Reporting'' 
(DBSR).

[[Page 31912]]

    NS accepted delivery of 50 new ES40DC locomotives from General 
Electric, which were equipped with DBSR systems as specified in the 
Association of American Railroads (AAR) Standard S-5509 (S-5509). At 
that time, S-5509 required the DBSR systems to operate on ANSI/EIA 
709.2 (Echelon PL-22) communication frequency on the C-band, which is 
the same communication band used by the Electronically Controlled 
Pneumatic (ECP) brake systems. On February 14, 2008, AAR modified S-
5509 by requiring the DBSR systems to use a communication frequency on 
A-band, instead of the C-band, to eliminate any interference problems 
the two systems could encounter using the same frequency band. This 
modification applies to all new locomotives, as well as a retrofit of 
locomotives presently equipped with DBSR systems employing the C-band.
    NS currently operates trains equipped with ECP brake technology 
that utilize many of the 50 locomotives that were equipped with the 
DBSR systems using the C-band communication configuration. These trains 
have experienced communication interference problems due to the two 
systems using the same C-band channel. Tests have shown that 
electrically disconnecting the DBSR system from the affected 
locomotives causes the communication interference to subside. 
Therefore, NS requests a temporary waiver of Sec.  232.109(g)(2) in 
order to electrically disconnect the DBSR system until the locomotives 
are modified with the new A-band DBSR system. In addition to these 
locomotives being equipped with functioning acceleration/deceleration 
displays per Sec.  232.109(h)(2), NS will continue to inform the 
locomotive engineer of the operational status of dynamic brakes on all 
locomotives, pursuant to Sec.  232.109(a) and (i). The locomotive 
numbers for this waiver request are NS 7670-7719.
    Interested parties are invited to participate in these proceedings 
by submitting written views, data, or comments. FRA does not anticipate 
scheduling a public hearing in connection with these proceedings since 
the facts do not appear to warrant a hearing. If any interested party 
desires an opportunity for oral comment, they should notify FRA, in 
writing, before the end of the comment period and specify the basis for 
their request.
