efficient planning and administration of 

the AIP. Absent the notification of 

intent to submit a grant application by 

the above-mentioned deadline, the FAA 

will carry over the available entitlement 

funds on May 16, 2025. These funds 

will not be available again to the airport 

sponsor until the beginning of FY 2026. 

The final grant application deadline 

for entitlement funds only is Monday, 

April 28, 2025. The final grant 

application funding requests should be 

based on bids, not estimates. Dates are 

subject to possible adjustment based on 

future legislation. As of the publication 

of this notice, the appropriations and 

the authorization legislation for the FAA 

expire on December 20, 2024, and 

September 30, 2028, respectively. 

Sponsors wishing to be considered for 

AIP discretionary funding throughout 

FY 2025 should submit applications as 

soon as possible to FAA Regional or 

Airport District Offices. The FAA 

considers all applications submitted if 

they meet all existing laws, Federal 

regulations, and FAA policy. 

The FAA considers applications on a 

rolling basis. The final deadline to 

submit grant applications competing for 

discretionary funding, in addition to 

entitlement funding, is June 16, 2025, by 

11:59 p.m. Eastern Daylight Time. 

Under 49 U.S.C. 47115, the FAA 

considers projects that are the most 

appropriate to carry out the statute at 

any time prior to September 30, 2025. 

The FAA has determined these 

deadlines will expedite and facilitate 

the FY 2025 grant-making process.

DEPARTMENT OF TRANSPORTATION 

Federal Railroad Administration 

[Docket Number FRA–2010–0044] 

Trinity Railway Express’s Request To 

Amend Its Positive Train Control 

Safety Plan and Positive Train Control 

System 

AGENCY: Federal Railroad 

Administration (FRA), Department of 

Transportation (DOT). 

ACTION: Notice of availability and 

request for comments. 

SUMMARY: This document provides the 

public with notice that, on October 30, 

2024, Trinity Railway Express (TRE) 

submitted its Positive Train Control 

Safety Plan (PTCSP), Version 2.0, dated 

October 30, 2024, to FRA’s Secure 

Information Repository. TRE asks FRA 

to approve its updated PTCSP and 

certify TRE’s Interoperable Electronic 

Train Management System (I–ETMS) as 

a ‘‘mixed’’ positive train control (PTC) 

system. As this RFA may involve a 

request for FRA’s approval of proposed 

material modifications to an FRAcertified PTC system, FRA is publishing 

this notice and inviting public comment 

on TRE’s RFA to its PTCSP. 

DATES: FRA will consider comments 

received by February 10, 2025 before 

taking final action on the PTCSP. FRA 

may consider comments received after 

that date to the extent practicable and 

without delaying implementation of 

valuable or necessary modifications to a 

PTC system. 

ADDRESSES: 

Comments: Comments may be 

submitted by going to https://

www.regulations.gov and following the 

online instructions for submitting 

comments. 

Instructions: All submissions must 

include the agency name and the 

applicable docket number. The relevant 

PTC docket number for this railroad is 

Docket No. FRA–2010–0044. For 

convenience, all active PTC dockets are 

hyperlinked on FRA’s website at https:// 

railroads.dot.gov/researchdevelopment/program-areas/traincontrol/ptc/railroads-ptc-dockets. All 

comments received will be posted

personal information.

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 

PTCSP, a host railroad must submit, and 

obtain FRA’s approval of, an RFA to its 

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 

October 30, 2024, TRE submitted an 

RFA to its PTCSP for its I–ETMS PTC 

system which seeks FRA’s approval to 

change the classification of its PTC 

system to a Mixed PTC system. In its 

PTCSP, TRE asserts that the I–ETMS 

PTC system it is implementing is a 

mixed PTC system as defined in title 49 

Code of Federal Regulations (CFR) 

236.1015(e). The PTCSP describes TRE’s 

I–ETMS implementation and the 

associated I–ETMS safety processes, 

safety analyses, and test, validation, and 

verification processes used during the 

development of I–ETMS. The PTCSP 

also contains TRE’s operational and 

support requirements and procedures. 

That RFA is available in Docket No. 

FRA–2010–0044. 

Interested parties are invited to 

comment on TRE’s RFA to its PTCSP by 

submitting written comments or data. 

During FRA’s review of TRE’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). However, FRA may elect 

not to respond to any particular 

comment, and under 49 CFR 

236.1009(d)(3), FRA maintains the 

authority to approve or disapprove the 

PTCSP at its sole discretion. 

Privacy Act Notice 

In accordance with 49 CFR 211.3, 

FRA solicits comments from the public 

to better inform its decisions. DOT posts 

these comments, without edit, including 

any personal information the 

commenter provides, to https://

www.regulations.gov, as described in 

the system of records notice (DOT/ALL– 

14 FDMS), which can be reviewed at 

https://www.transportation.gov/privacy. 

See https://www.regulations.gov/

regulations.gov. To facilitate comment 

tracking, we encourage commenters to 

provide their name, or the name of their 

organization; however, submission of
