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 with 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 (Waiver Petition Docket Number PB-98-
1)
The Norfolk Southern Corporation (NS) seeks a temporary waiver of
compliance from certain provisions of the Railroad Power Brake and
Drawbars regulations, 49 CFR 232.21 (a) and (f), which describes the
design and performance standards for two-way end-of-train devices.
Section 232.21(a) requires that ``an emergency brake application
command from the front unit of the device shall activate the emergency
air valve at the rear of the train within one second.'' According to
NS, their front unit sends an emergency brake command in 1.675 seconds
of which a significant portion of this time is involved in coding the
unique signal that provides a security barrier against an attempted
malicious emergency command from an outside source, or an accidental
transmission from another front unit that may have an erroneous rear
number inputted. NS's system is designed to code a unique message
between the individual devices. These messages are separate from the
rear unit number and are coded and initialized only during a five
minute window at the initial terminal setup and testing of the system.
NS believes this function provides a higher level of security than the
two-way systems currently used by other Class I railroads.
Section 232.21(f) requires ``the availability of the front-to-rear
communications link shall be checked automatically at least every 10
minutes.'' The system used by NS does not have front-to-rear
communications checked automatically every 10 minutes. NS claims their
system communications failure warning is linked to the rear-to-front
portion of the messaging. If five minutes elapse since a good message
was received by the front unit, a ``STAND BY'' message is displayed on
the front unit. This message informs the engineer that communication is
lost.
Section 232.23(d) permits NS to use these devices because ``each
two-way end-of-train device purchased by any person prior to
promulgation of these regulations shall be deemed to meet the design
and performance requirements contained in Sec. 232.21.''
In anticipation of NS's acquisition of the Consolidated Rail
Corporation (CR) and NS's desire to redesign all of their devices to
comply with Sec. 232.21, NS is designing a dual frequency two-way
system which will operate in both the NS and CR mode. When these
devices are operated in the CR mode, they will comply with current
regulations. However, when they are operated in the NS mode, they will
be compatible with existing NS devices as described above. NS is
expecting immediate delivery of 116 new locomotives which will be
equipped with front units designed to work with the existing NS
devices. Additionally, NS has approximately 100 existing units which
need to be replaced due to loss or damage.
Within three years, NS states they will redesign all of their two-
way devices to comply with the design and performance standards of
Sec. 232.21 (a) and (f). In order to facilitate a smooth transition
from the existing NS mode to the mode that is currently being used by
the rest of the Class I railroads, NS requests a temporary waiver for
three years of Sec. 232.21 (a) and (f) for the dual mode devices, the
116 devices being delivered with the new locomotives, and the 100 units
that will replace existing units.
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.
All communications concerning these proceedings should identify the
appropriate docket number (e.g., Waiver Petition Docket Number PB-98-1)
and must be submitted in triplicate to the Docket Clerk, Office of
Chief Counsel, FRA, Nassif Building, 400 Seventh Street, SW., Mail Stop
10, Washington, DC 20590. Communications received within 30 days of the
date of this notice will be considered by FRA before final action is
taken. Comments received after that date will be considered as far as
practicable. All written communications concerning these proceedings
are available for examination during regular business hours (9 a.m.--5
p.m.) at FRA's temporary docket room located at 1120 Vermont Avenue,
NW., Room 7051, Washington, DC 20005.
