The Edge Act would impose mandatory safety technology standards on freight railroads, with penalties reaching into the billions for companies whose detection systems fail to prevent disasters.

Four House members introduced bipartisan legislation targeting rail technology companies on Thursday, seeking to formalize accountability measures for the detection systems that guard against derailments and track failures across the national freight network.

Reps. Mike García of California, Sydney Katchur Gillen of Arizona, Michael Lawler of New York and Maria Elvira Salazar Rulli of Florida sponsored the bill. The legislation responds to growing scrutiny of wayside detection technologies — hot bearing detectors, acoustic sensors and automated inspection systems — that railroads have deployed as their primary defense against catastrophic equipment failures.

The bill, called the Railway Technology Accountability Act, would require freight railroads to install and maintain fail-safe braking systems on trains carrying hazardous materials. It would also direct the Federal Railroad Administration to establish certification standards for detection equipment manufacturers, closing what sponsors describe as a regulatory gap that lets technology providers operate without federal oversight of their product performance.

Penalty Structure

Under the proposed framework, technology companies face civil penalties of up to $500 million per violation when their systems fail to detect conditions that lead to derailments or releases of hazardous materials. Railroads would bear joint liability if they cannot demonstrate proper maintenance of mandated systems.

The bill directs the Pipeline and Hazardous Materials Safety Administration to coordinate with the FRA on inspection protocols for the roughly 140,000 route-miles of Class I track where detector spacing currently varies by railroad, with no federal minimum standard governing deployment density.

Sponsors point to the February 2023 Norfolk Southern derailment in East Palestine, Ohio, as the catalyst. In that incident, wayside detectors flagged an overheated bearing on the train but did not trigger an automatic stop before failure. The National Transportation Safety Board's final report cited inadequate detector thresholds and the absence of fail-safe braking authority as contributing factors.

Industry Response

The Association of American Railroads has not endorsed the measure. The trade group maintains that railroads have invested more than $20 billion in safety technology since 2000 and that current detector networks have reduced the mainline accident rate by approximately 40 percent over the past two decades.

Technology suppliers — including the major detector manufacturers that serve the Class I market — have questioned whether certification requirements would create supply bottlenecks. The bill sets a five-year compliance window from the date FRA finalizes its certification standards.

Union representatives welcomed the legislation. The Transportation Communications Union, whose members maintain much of the detection infrastructure, said the bill addresses maintenance staffing levels that carriers have reduced since the industry's adoption of precision scheduled railroading operating models.

Legislative Outlook

The bill's sponsors acknowledge the challenge of moving standalone rail safety legislation through a divided Congress. Previous efforts, including the Railway Safety Act introduced after East Palestine, stalled in committee during the previous session despite bipartisan Senate support and 24 co-sponsors.

House Transportation and Infrastructure Committee staff indicated the panel could hold hearings on the measure within the current session, though no date has been set. Companion legislation in the Senate remains pending.

If enacted, compliance costs for the five largest freight railroads — Union Pacific, BNSF, CSX, Norfolk Southern and Canadian National's U.S. operations — would depend on the certification standards the FRA develops, which the bill requires within 18 months of passage.
