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 (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.
