# 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 49 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 PTCSP, a host railroad must submit, and obtain FRA's approval of, an RFA to its PTCSP under Title 49 Code of Federal Regulations (CFR) Section 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 and train control system. Accordingly, this notice informs the public that host railroads' recent RFAs to their PTCSPs are available in their respective public PTC dockets, and this notice provides an opportunity for public comment on these RFAs.                

On July 16, 2021, the following 19 host railroads jointly submitted an RFA to their respective PTCSPs for their Interoperable Electronic Train Management Systems (I-ETMS): Alaska Railroad Corporation (ARR), The Belt Railway Company of Chicago (BRC), BNSF Railway (BNSF), Peninsula Corridor Joint Powers Board (PCMZ), Canadian National Railway (CN), Canadian Pacific Railway (CP), Consolidated Rail Corporation (CRSH), CSX Transportation, Inc. (CSX), Kansas City Terminal Railway (KCT), Kansas City Southern Railway (KCS), National Passenger Railroad Corporation (Amtrak), New Mexico Rail Runner Express (NMRX), Northeast Illinois Regional Commuter Railroad Corporation (Metra), Northern Indiana Commuter Transportation District (NICD), Norfolk Southern Railway (NS), South Florida Regional Transportation Authority (SFRV), Southern California Regional Rail Authority (Metrolink), Terminal Railroad Association of St. Louis, and Union Pacific Railroad (UP). Their joint RFA is available in Docket Numbers FRA-2010-0028, -0029, -0039, -0042, -0043, -0045, -0048, -0051, -0054, -0056, -0057, -0058, -0059, -0060, -0061, -0062, -0064, -0065, and -0070.

                    Interested parties are invited to comment on any RFAs to railroads' PTCSPs by submitting written comments or data. During FRA's review of railroads' RFAs, 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 PTC systems.                     *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 railroads' RFAs to their PTCSPs at FRA's sole discretion.
