                        Gabe Neal, Staff Director, Signal, Train Control, and Crossings Division, telephone: 816-516-7168, email:                         *Gabe.Neal@dot.gov.*

# SUPPLEMENTARY INFORMATION:

In general, title 49 United States Code (U.S.C.) section 20157(h) requires FRA to certify that a host railroad's PTC system complies with title 49 Code of Federal Regulations (CFR) part 236, subpart I, before the technology may be operated in revenue service. Before making certain changes to an FRA-certified PTC system or the associated FRA-approved PTC Safety Plan (PTCSP), a host railroad must submit, and obtain FRA's approval of, an RFA to its PTC system or PTCSP under 49 CFR 236.1021.

                    Under 49 CFR 236.1021(e), FRA's regulations provide that FRA will publish a notice in the                     **Federal Register**                     and invite public comment in accordance with 49 CFR part 211, if an RFA includes a request for approval of a material modification of a signal or train control system. Accordingly, this notice informs the public that, on January 24, 2024, NICD submitted an RFA to its Interoperable Electronic Train Management System (I-ETMS), which seeks FRA's approval for NICD to temporarily disable its PTC system's current Back Office System (BOS) during the implementation of the Railcomm BOS. That RFA is available in Docket No. FRA-2010-0043.                

                    Interested parties are invited to comment on NICD's RFA by submitting written comments or data. During FRA's review of this railroad's RFA, FRA will consider any comments or data submitted within the timeline specified in this notice and to the extent practicable, without delaying implementation of valuable or necessary modifications to a PTC system.                     *See*49 CFR 236.1021;                     *see also*49 CFR 236.1011(e). Under 49 CFR 236.1021, FRA maintains the authority to approve, approve with conditions, or deny a railroad's RFA at FRA's sole discretion.
