Summary

Railroads that run intercity or commuter passenger trains must check their whole system and find each main-track spot where the speed drops by more than 20 miles per hour from the approach speed to a curve, bridge, or tunnel, and note the maximum allowed passenger speed at those spots. They had to finish that survey by March 3, 2016. Within 120 days after finishing a survey, the railroad must send the Secretary of Transportation an action plan that lists those locations, explains how the railroad will warn crews and enforce the speed limit (for example, changes to automatic train control or signals, more crew members or communication, signs, alerters, or other practices), gives milestones and target dates, and promises to ensure compliance. The Secretary must approve, approve with conditions, or disapprove the plan within 90 days of receiving it. Railroads must review the plan within 1 year after the Passenger Rail Expansion and Rail Safety Act of 2021 was enacted and then every year, and must send a revised plan at least 90 days before any big operational or territory change after consulting any host railroad. If a railroad did not exist when the FAST Act was enacted, it must survey routes within 90 days after the Passenger Rail Expansion and Rail Safety Act of 2021 was enacted and file a plan within 120 days after the survey. The Secretary can exempt track segments that have a certified positive train control system under section 20157 or other safety tech that gives equal or better protection. No new intercity or commuter passenger service may start unless the railroad meets these requirements. The Secretary can also apply these rules to other track segments at high risk of overspeed derailment.

(a)Not later than March 3, 2016, each railroad carrier providing intercity rail passenger transportation or commuter rail passenger transportation, in consultation with any applicable host railroad carrier, shall survey its entire system and identify each main track location where there is a reduction of more than 20 miles per hour from the approach speed to a curve, bridge, or tunnel and the maximum authorized operating speed for passenger trains at that curve, bridge, or tunnel.
(b)Not later than 120 days after the date that the survey under subsection (a) is complete, a railroad carrier described in subsection (a) shall submit to the Secretary of Transportation an action plan that—
(1)identifies each main track location where there is a reduction of more than 20 miles per hour from the approach speed to a curve, bridge, or tunnel and the maximum authorized operating speed for passenger trains at that curve, bridge, or tunnel;
(2)describes appropriate actions to enable warning and enforcement of the maximum authorized speed for passenger trains at each location identified under paragraph (1), including—
(A)modification to automatic train control systems, if applicable, or other signal systems;
(B)increased crew size;
(C)installation of signage alerting train crews of the maximum authorized speed for passenger trains in each location identified under paragraph (1);
(D)installation of alerters;
(E)increased crew communication; and
(F)other practices;
(3)contains milestones and target dates for implementing each appropriate action described under paragraph (2); and
(4)ensures compliance with the maximum authorized speed at each location identified under paragraph (1).
(c)Not later than 90 days after the date on which an action plan is submitted under subsection (b) or (d)(2), the Secretary shall approve, approve with conditions, or disapprove the action plan.
(d)Each railroad carrier that submits an action plan to the Secretary pursuant to subsection (b) shall—
(1)not later than 1 year after the date of enactment of the Passenger Rail Expansion and Rail Safety Act of 2021, and annually thereafter, review such plan to ensure the effectiveness of actions taken to enable warning and enforcement of the maximum authorized speed for passenger trains at each location identified pursuant to subsection (b)(1); and
(2)not later than 90 days before implementing any significant operational or territorial operating change, including initiating a new service or route, submit to the Secretary a revised action plan, after consultation with any applicable host railroad, that addresses such operational or territorial operating change.
(e)If a railroad carrier providing intercity rail passenger transportation or commuter rail passenger transportation did not exist on the date of enactment of the FAST Act (Public Law 114–94; 129 Stat. 1312), such railroad carrier, in consultation with any applicable host railroad carrier, shall—
(1)survey its routes pursuant to subsection (a) not later than 90 days after the date of enactment of the Passenger Rail Expansion and Rail Safety Act of 2021; and
(2)develop an action plan pursuant to subsection (b) not later than 120 days after the date on which such survey is complete.
(f)The Secretary may exempt from the requirements under this section each segment of track for which operations are governed by a positive train control system certified under section 20157, or any other safety technology or practice that would achieve an equivalent or greater level of safety in reducing derailment risk.
(g)No new intercity or commuter rail passenger service may begin operation unless the railroad carrier providing such service is in compliance with the requirements under this section.
(h)Nothing in this section may be construed to prohibit the Secretary from applying the requirements under this section to other segments of track at high risk of overspeed derailment.
