The DERAIL Act directs the Secretary of Transportation to issue regulations redefining what counts as a high-hazard flammable train. The definition would cover trains carrying one or more loaded tank cars of Class 3 flammable liquids or Class 2 flammable gases, plus other materials the Secretary determines necessary for safety, with a 90-day deadline after enactment.
The bill also adds a new reporting requirement: derailments involving material toxic by inhalation must be reported within 24 hours to the National Response Center, state officials, local officials, and Tribal governments. To formalize this requirement, the bill includes a clerical amendment to add a new section to the U.S. Code.
The overall aim is to improve safety oversight and incident response by tightening definitions and accelerating information flow to responders.
At a Glance
What It Does
Within 90 days after enactment, the Secretary must amend 49 CFR 171.8 to redefine 'high-hazard flammable train' to include trains with one or more loaded tank cars of Class 3 liquids or Class 2 gases plus other materials the Secretary deems necessary for safety. The bill also requires derailments involving material toxic by inhalation to be reported within 24 hours to the National Response Center, state officials, local officials, and Tribal governments. Finally, it adds a clerical amendment to Title 49 to insert a new reporting subsection.
Who It Affects
Rail carriers operating high-hazard shipments, regulation and compliance staff, and emergency management offices at the state, local, and Tribal levels, as well as federal regulators coordinating responses.
Why It Matters
The changes create clearer safety thresholds, faster information sharing after derailments, and a formal mechanism to track incidents involving inhalation hazards, enabling more timely responses and data-driven oversight.

What This Bill Actually Does
Section 1 establishes the act’s short title, the DERAIL Act. Section 2 directs the Department of Transportation to issue regulations within 90 days that amend the definition of a high-hazard flammable train.
The new definition would include trains carrying one or more loaded tank cars of Class 3 flammable liquids or Class 2 flammable gases, along with other materials the Secretary determines necessary for safety. This is a widening of the safety perimeter around what counts as a high-hazard operation and signals a more proactive regulatory posture for rail safety.
The Five Things You Need to Know
The bill requires the Secretary of Transportation to issue regulations within 90 days to redefine 'high-hazard flammable train'.
The new definition includes trains with one or more loaded tank cars of Class 3 liquids or Class 2 gases and other materials designated for safety by the Secretary.
A new reporting duty requires derailments involving material toxic by inhalation to be reported within 24 hours to the National Response Center and state, local, and Tribal officials.
A clerical amendment to Title 49 adds §20904, creating a formal reporting framework for accidents involving inhalation hazards.
There is no explicit funding in the bill; it relies on existing regulatory and reporting frameworks to implement the changes.

Short title
This section provides the act’s formal citation as the DERAIL Act (Decreasing Emergency Railroad Accident Instances Locally Act). It establishes the legislative hook for the rest of the provisions.
High-hazard flammable train definition and regulatory deadline
Not later than 90 days after enactment, the Secretary must amend 49 CFR 171.8 to modify the definition of 'high-hazard flammable train' to mean a train carrying one or more loaded tank cars of Class 3 flammable liquids or Class 2 flammable gases, plus other materials the Secretary determines necessary for safety. This expands the safety scope and sets a concrete timeline for regulatory action.
Reporting of accidents involving material toxic by inhalation
The bill adds a new statutory provision (20904) requiring derailments involving material toxic by inhalation to be reported within 24 hours to the National Response Center, state officials, local officials, and Tribal governments. This section also includes a clerical amendment adding the new reporting requirement to the analysis for Chapter 209 of Title 49.
Clerical amendment to Title 49
This section codifies the administrative update by inserting the new §20904 into Chapter 209 of Title 49, United States Code, to formalize the reporting requirement for accidents involving material toxic by inhalation.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- National Response Center and federal responders gain faster access to incident data and improved coordination during derailments involving inhalation hazards.
- State emergency management agencies obtain earlier notification and better situational awareness for responding to derailments.
- Local emergency responders receive timely information to coordinate on-site actions and protective measures.
- Tribal governments gain direct channels for sharing information and coordinating response in affected areas.
- Rail carriers operating high-hazard train shipments benefit from clearer regulatory definitions and expectations.
Who Bears the Cost
- Rail carriers and their compliance teams face enhanced reporting obligations and potential operational adjustments to meet 24-hour deadlines.
- State and local governments must integrate the new reporting flow into existing emergency-mroadcast and data-sharing systems.
- Federal regulators will process and analyze incoming reports more frequently, increasing administrative workload.
- Communities in corridors with high derailment risk may incur costs related to heightened preparedness and notification requirements.
- Tribal governments may need to coordinate with federal and state partners to ensure prompt reporting and response.
Key Issues
The Core Tension
Balancing the need for rapid, robust safety upgrades and transparent reporting with the risk of regulatory overreach and implementation burden on railroads and local responders.
The DERAIL Act introduces a sharper safety perimeter around what counts as a high-hazard train, and it accelerates the flow of information after derailments involving inhalation hazards. While the intent is clear—improve safety and emergency response—the bill raises several tensions.
The 90-day deadline places pressure on regulatory drafting, validation, and interagency coordination, which can affect the quality and clarity of the final rule. The scope of 'other materials the Secretary determines necessary for safety' could broaden or drift over time, potentially creating uncertainty for operators and the regulated community.
The 24-hour reporting requirement shifts a substantial amount of information-management risk to railroad carriers and local and state authorities without specified funding for implementation. Finally, the clerical amendment, while routine, consolidates new reporting duties into the Code, but without accompanying implementation guidance, real-world compliance may hinge on agency rulemaking and intergovernmental collaboration.
