[Docket Number FRA-2017-0123]

Petition for Waiver of Compliance

    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

solid-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.
    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 Department of Transportation's
