DEPARTMENT OF TRANSPORTATION
[Waiver Petition Docket Numbers H-94-3 and H-94-4]
Petition for Waiver for Test Program National Railroad Passenger
Corporation (Amtrak)
In accordance with 49 CFR Part 211, notice is hereby given that
Amtrak submitted two related petitions, dated May 26, 1994 and June 7,
1994, respectively, for waivers of compliance with specific
requirements of certain parts of Title 49 of the Code of Federal
Regulations to conduct two separate test programs to evaluate the
curving performance of a passenger trainset under high-speed and
curving conditions.
The State of New York has embarked on a multi-year program to
develop high-speed rail service between Buffalo and New York City. The
State is actively pursuing the upgrading or elimination of rail
crossings; existing rolling stock is being modified to run at higher
speeds; and, improvements are being made to the right-of-way in
preparation for this service. A major short-term goal of this program
is to evaluate the curving performance of a modified Amtrak RTL
turboliner passenger trainset and Amtrak has petitioned FRA to conduct
two separate test and demonstration programs.
The program is being partially funded by FRA under Section 1036(c)
of the Intermodal Surface Transportation Efficiency Act for a
Technology Demonstration Program; significant funding is also being
provided by the State of New York and Amtrak.
Waiver Petition H-94-3, dated June 7, 1994
Should petition H-94-3 be approved, Amtrak expects to schedule no
more than 25 test and demonstration runs on two test zones between
September 1, 1994 and January 31, 1995. The test zones over which these
tests will be run are Conrail's Hudson Line, track 2 between CP 125 and
CP 141 (approximate mileposts 125.5 to 140.5), and Conrail's Chicago
Line, single track between milepost 149 and CP 156 (approximate
milepost 156.4). The tracks are presently FRA Class 6. In 1983, FRA
recognized Amtrak as the party responsible for compliance with the
Federal Track Safety Standards for segments of Conrail's Hudson and
Chicago Lines that include the two test zones.
To accomplish the tests and demonstrations, Amtrak is requesting
FRA to temporarily waive 49 CFR 213.9(c), ``Classes of track: operating
speed limit,'' to allow the test trainset to operate at a maximum speed
of 125 mph, and 49 CFR 213.57(b), ``Curves; elevations and speed
limitations,'' to allow operation at up to five inches of cant
deficiency.
In order to reach and sustain 125 mph in one proposed test zone,
Amtrak advises that a curve at milepost 135, track 2, is being
realigned to ease its curvature; spirals are being lengthened; and
superelevation is being increased to six inches. Amtrak advises that
both zones will be resurfaced. Despite this track work, Amtrak still
anticipates the need to operate on some curves at cant deficiencies as
high as five inches and requests a waiver for cant deficiency.
The track safety standards in 49 CFR 213.57(b) prescribe a speed
limit, not distinguishing between freight and passenger rolling stock,
at which trains may operate over curved track as a function of curve
radius (curvature) and installed superelevation.
In the general case, for any combination of curvature and
superelevation, there is a specific (``balanced'') speed at which the
effect of centrifugal force is canceled, resulting in passenger
insensitivity to actual curve negotiation. This is an ideal outcome for
passenger trains that usually operate considerably faster than freight
trains and consequently would demand greater superelevation to produce
the balanced effect. The track standards permit the operation of trains
on curves at speeds producing a conservative underbalance (``cant
deficiency'') in line with historic industry practice. (A more detailed
discussion of cant deficiency can be found in 52 FR 38035, October 13,
1987).
Amtrak has indicated that its geometry car will be run over the
test zones in the month before the commissioning tests begin and will
be run bi-monthly during the test program. Amtrak advises that all
defects will be corrected before the 125 mph operation begins or is
allowed to continue.
Amtrak states that, during the high-speed runs where speeds exceed
110 mph, each private and public crossing will be physically barricaded
and monitored by a guard in advance of the arrival of each test train.
Amtrak indicates that radio contact will be maintained with the guards
and that the adequacy of the present signal spacing will be verified
before the program begins.
When the test program is completed in January 1995, Amtrak advises
the track speed will return to 110 mph and three inches of cant
deficiency will be observed.
Waiver Petition H-94-4, Dated May 26, 1994
Should petition H-94-4 be approved, pending right-of-way
improvements and the initiation of the test program requested under
petition H-94-3 on the Hudson and Chicago Lines in New York State,
Amtrak expects to demonstrate the modified RTL turboliner trainset on
the Northeast Corridor between Washington and New York on those tracks
where Amtrak is presently operating equipment at 125 mph. Amtrak
expects to schedule no more than 25 test and demonstration runs between
September 1, 1994 and January 31, 1995 on the Northeast Corridor. To
demonstrate this trainset, Amtrak is asking FRA to waive 49 CFR
213.9(c), ``Classes of track: operating speed limit,'' to allow this
trainset to operate at 125 mph. Petition H-94-4 does not request relief
from the requirements of 49 CFR 213.57(b) relating to cant deficiency
on curves.
Modified RTL Turboliner Trainset
Amtrak advises that both power units of one RTL turboliner trainset
are being retrofitted with higher horsepower Makila turbines to allow
faster accelerations and higher speeds and the hydraulic transmissions
and control system are being modified to accommodate the increased
horsepower.
FRA's Approach
FRA's approach to ensuring safety if the two petitions are granted
would be to require that sufficient instrumentation be installed on the
trainset to enable comparison of equipment behavior during testing to
predetermined derailment criteria and, also, to previously tested
equipment of similar types known to be safe. FRA would require that
attainment of maximum target curving speeds be in increments permitting
a step-by-step analysis of applied forces and dynamic responses during
and at the conclusion of each test run. The decision to go to the next
level of cant deficiency or speed would be based on this analysis
process and be subject to the approval of the on-board FRA test
monitor.
Public Comment
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 hearing, 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., FRA Docket Nos. H-94-3 and H-94-4) and
must be submitted in triplicate to the Docket Clerk, Office of Chief
Counsel, Federal Railroad Administration, Nassif Building, 400 Seventh
Street, S.W., Washington, D.C. 20590. Communications received within 30
days of publication 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.) in Room 8201, Nassif Building, 400 Seventh Street
SW., Washington, D.C. 20590.
Issued in Washington, D.C. on July 25, 1994.

Development.
