DEPARTMENT OF TRANSPORTATION
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.
CSX Transportation
[Docket Number FRA-2007-28612]
CSX Transportation (CSX) seeks a permanent waiver of compliance
from certain provisions of the Locomotive Safety Standards, 49 CFR
229.129(c), as it pertains to railroad locomotive horn testing. CSX
seeks to utilize an automated sound measurement system (ASMS) to test
locomotive horns as required in Sections 229.129(a) and (b). The ASMS
utilizes a Class 1 sound-level measuring instrument that is permanently
mounted in a fixed test site and uses the same technology that is used
to measure noise at airports nationwide.
CSX requests to extend the requirement for acoustic calibration (49
CFR 229.129(c)(2) and (9)) from immediately before and after each
session of compliance tests to a period of not more than every 6
months. The 6-month period is to be extended to 1 year if the system
demonstrates a history of stability that indicates the 6-month testing
is unnecessary. CSX states in their petition that the ASMS is equipped
with an electrostatic test device that monitors acoustic calibration,
and that they would review these tests daily and perform calibration as
needed.
In addition, CSX requests a waiver to reduce the requirement from a
locomotive needing a 200-foot clearance (49 CFR 229.129(c)(5)) to the
front and sides from large reflective surfaces to 150 feet at the side
clearance. CSX states in their request that they performed horn testing
at 150 feet and again at the required 200 feet with no measurable
difference in meter readings. A reduction in the side clearance would
assist the railroad in finding suitable test sites closer to their
maintenance facilities.
Finally, CSX requests a waiver from the requirement of testing cab-
and low-mounted horns (49 CFR 229.129(c)(7)) at a 4-foot level in order
to allow all locomotive horns to be tested at the 15-foot level. CSX
feels that testing all horns at the 15-foot level would provide more
consistent and meaningful measurements for both types of horn
mountings. CSX testing shows that cab- and low-mounted horns showed
reduced sound measurement at the 4-foot level compared to the 15-foot
level, due to the effect of the acoustic shadow created by the
locomotive.
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
