Start Preamble

Under part 211 of Title 49 Code of Federal Regulations (CFR), this provides the public notice that on November 27, 2017, the Canadian National Railway (CN) petitioned the Federal Railroad Administration (FRA) for relief from the requirements of 49 CFR 236.23, Aspects and indications, to allow CN to display a dark aspect as a “stop.” FRA assigned the petition Docket Number FRA-2017-0123.

The regulation requires that a red signal aspect must be displayed for a “stop” indication. In its petition, CN requests relief from this requirement, and explains that with the use of advanced processor technology in the railway signaling field, failsafe checks that have never before been incorporated into the wayside signal system can now economically be provided. In CN's particular case, the Start Printed Page 61121solid-state electronics have the ability to monitor lamp driver circuits for foreign and/or undesired voltage. CN explains that if the lamp driver monitoring circuits detect foreign or undesirable voltage, all voltage produced by the lamp driver is switched off by the central processing unit as defined by the executive software. CN states that this relief would allow a continuing and industry-wide practice that ensures absolute safety under undesirable conditions. These conditions include but are not limited to, component failures on lamp driver modules, grounds, incorrect9*/wiring and cross connections.

CN's position is that it is far safer to remove all operating voltage to affected lamps, versus running the risk of having an undesired aspect displayed. The relief is sought for all current solid-state applications and all future solid-state applications on CN Southern Region, inclusive of all United States properties.
