DEPARTMENT OF TRANSPORTATION
Petition for Exemption or Waiver of Compliance
In accordance with 49 CFR 211.9 and 211.41, notice is hereby given
that the Federal Railroad Administration (FRA) has received from the
Association of American Railroads (AAR) a request for an interim waiver
of compliance with a requirement of Federal rail safety standards. The
petition is described below, including the regulatory provisions
involved and the nature of the relief being requested.
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 RSFC-94-
2) and must be submitted in triplicate to the Docket Clerk, Office of
Chief Counsel, Federal Railroad Administration, Nassif Building, 400
Seventh Street SW., Washington, DC 20590. Communications received
before December 1, 1994, 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.) in Room 8201, Nassif Building, 400 Seventh Street SW.,
Washington, DC 20590.
Association of American Railroads (AAR)--(Waiver Petition Docket
Number RSFC-94-2)
The Association of American Railroads (AAR) seeks an interim waiver
of compliance with certain provisions of the Railroad Freight Car
Safety Standards, 49 CFR Part 215. The AAR is requesting an exemption
from the requirement of 49 CFR 215.103(h) which requires the removal
from service of freight car wheels that show signs of having been
overheated as evidenced by reddish brown discoloration, as it is
applied to heat-treated curved-plate wheels. As a result of a petition
by the AAR (Rulemaking Petition No. 93-1), the FRA intends to initiate
a rulemaking addressing the proposal to revise 49 CFR 215.103(h) as it
applies to heat-treated curved-plate (HT-CP) freight car wheels.
AAR indicates that it is filing this petition for an interim waiver
to address the situation while the rulemaking process proceeds.
AAR requests that FRA issue a waiver providing in substance, that:
49 CFR 215.103 shall not prohibit a railroad from placing or
continuing in service a freight car if the only reason for such
prohibition is one or more wheels that are discolored as described in
49 CFR 215.103(h), provided:
(i) Each such discolored wheel is heat-treated and is of curve-
plate design,
(ii) Each such wheel is identified as a heat-treated curved-plate
wheel in accordance with AAR interchange rules, and
(iii) The railroad has submitted to FRA and to AAR a written
agreement to participate in the Data Collection Program on Premature
Wheel Failure.
AAR cites the following justification for the waiver request:
1. HT-CP wheels are extraordinarily resistant to the development of
residual tensile rim stresses which are a precondition for wheel
fracture.
2. The resistance of HT-CP wheels to development of residual
tensile rim stress is a function of the design of the wheels and the
manufacturing processes used.
3. In-service wheel failure data and experimental data show that
HT-CP wheels have an incidence of residual tensile rim stress and of
wheel failure that is approximately the same as non-discolored HT-CP
wheels.
4. Transport Canada, the Canadian rail safety agency, does not
prohibit the use of discolored curved-plate wheels on railroad freight
cars. Canadian data collected over nine years similarly show that
discolored and non-discolored HT-CP wheels fail for residual tensile
rim stress related reasons at approximately the same rate.
5. New air brake testing procedures have significantly reduced the
likelihood of sticking brakes--the principal cause of the development
of residual tensile rim stress in HT-CP wheels.
6. Removal of HT-CP wheels costs the railroad industry
approximately $40 million per year, yet provides no discernible safety
benefit.
Data Collection on Premature Wheel Failure
AAR proposes a data collection program that will provide a data
base which can be used to make sound decisions about railroad freight
car wheels, particularly HT-CP wheels.

Implementation.
