2018-09400. Petition for Waiver of Compliance

Under part 211 of Title 49 Code of Federal Regulations (CFR), this document provides the public notice that on April 13, 2018, Ritron, Inc. (Ritron) petitioned the Federal Railroad Administration (FRA) for a waiver of compliance from certain provisions of the Federal railroad safety regulations contained at 49 CFR 232.409(d). FRA assigned the petition Docket Number FRA-2009-0015.

Ritron is seeking to extend its waiver of compliance from 49 CFR 232.409(d) for three models of its two-way transceiver radios used for the link modules inside Head-of-Train (HOT) and End-of-Train (EOT) devices. These three models are DTX-445, DTX-454, and DTX-460. These models use a master reference oscillator to determine the frequency stability of the transmitted signal. The actual transmitted signal is phase-locked to this master oscillator by a phase-locked loop. This self-calibrating procedure eliminates the need for yearly re-calibrations. Ritron states that if the radio is operating, it is within specifications. Ritron originally received a waiver of compliance on July 21, 2010. Ritron received an updated waiver, to add another radio to that included in the original request, on September 4, 2013.

A copy of the petition, as well as any written communications concerning the petition, is available for review online at www.regulations.gov and in person at the U.S. Department of Transportation's (DOT) Docket Operations Facility, 1200 New Jersey Avenue SE, W12-140, Washington, DC 20590.
