Federal Railroad Administration

[Docket Number FRA-2021-0043]


Petition for Waiver of Compliance

    Under part 211 of title 49 of the Code of Federal Regulations 
(CFR), this provides the public notice that by letter dated March 31, 
2021, Denver Transit Operators (DTO) petitioned the Federal Railroad 
Administration (FRA) for a waiver of compliance from certain provisions 
of the Federal railroad safety regulations contained at 49 CFR part 
236, Rules, Standards, and Instructions Governing the Installation, 
Inspection, Maintenance, and Repair of Signal and Train Control 
Systems, Devices, and Appliances. FRA assigned the petition Docket 
Number FRA-2021-0043.
    Specifically, DTO seeks relief from the 2-year periodic testing 
requirements in 49 CFR 236.377, Approach locking; 49 CFR 236.378, Time 
locking; 49 CFR 236.379, Route locking; 49 CFR 236.380, Indication 
locking; and 49 CFR 236.381, Traffic locking. DTO also requests relief 
from the 1-year periodic testing period of 49 CFR 236.109, Time 
releases, timing relays, and timing devices, on all vital 
microprocessor-based systems.
    DTO states that all control points and other locations are 
controlled by solid-state vital microprocessor-based systems, which 
utilize programmed logic equations in lieu of relays or other 
mechanical components for control of both vital and non-vital 
functions. DTO further states that the logic does not change once a 
microprocessor-based system has been tested and that locking tests are 
documented on installation.
    A copy of the petition, as well as any written communications 
concerning the petition, is available for review online at 
www.regulations.gov.
    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 
desires an opportunity for oral comment, they should notify FRA, in 
writing, before the end of the comment period and specify the basis for 
their request.
