Assembly hearing on AB 446 spotlights rail-safety concerns and preemption questions

Carson City — The Assembly Committee on Growth and Infrastructure considered Assembly Bill 446, a comprehensive rail-safety package that would set state-level requirements for freight operations, including a cap on train length, mandatory wayside defect detectors, limits on blocked crossings, yard-lighting and worker-access and reporting provisions.

Sponsor remarks and rationale

Assemblymember Max Carter framed AB 446 as a response to operational changes industrywide: "AB 4 46 limits the length of freight and work trains to 8,500 feet," he said in prepared remarks, and the bill would require hot-box detectors every 10 miles, prohibit prolonged blocking of crossings and strengthen worker and yard safety standards. He said the bill responds to longer trains, reduced crews and a rise in mechanical failures reported by rail workers.

Unions and rail workers

A string of railroad employees and union representatives testified in favor. Gabe Christiansen, a conductor and Nevada safety and legislative director for SMART-TD, said the industry increased typical train lengths from roughly 6,000 feet to over 15,000 feet in recent years and linked longer, heavier trains to higher rates of mechanical failures, derailments and operational incidents. Matthew Parker of the Brotherhood of Locomotive Engineers and Trainmen cited National Academies of Sciences, Engineering, and Medicine (NASEM) findings that derailment risk rises above about 7,500 feet, and he urged state oversight where federal guidance has not prompted sufficient change.

Supporters asked the legislature to add enforcement tools — incident reporting to the Public Utilities Commission, bonds for derailments, financial penalties for blocked crossings that impede emergency responders, and required hot-box detectors — and to permit union safety representatives greater access for safety inspections and investigations.

Railroad industry and business opposition

Representatives of Class I railroads — including Union Pacific and Burlington Northern Santa Fe — opposed AB 446. Union Pacific counsel Joseph Guild emphasized legal risk, citing United States Supreme Court precedent (Southern Pacific Co. v. Arizona) and federal preemption under the Interstate Commerce Commission Termination Act; he said state regulation of train length would likely be preempted. Union Pacific witnesses described investments in safety technology — physics-based train simulations, wayside detectors, and operational practices — and argued that prescriptive state mandates would duplicate federal oversight, raise costs, slow freight movement and increase greenhouse-gas emissions by requiring more, shorter trains.

Local government, labor and business response

Local elected officials, building trades, trucking and logistics groups offered mixed responses. Many local unions, city representatives and labor organizations urged the committee to adopt the bill to protect workers and communities. Business groups (chambers, logistics operators, and trucking associations) warned of supply-chain impacts, higher consumer costs and conflicts with interstate commerce.

Legal complexity and next steps

The hearing included a legal presentation from Lawrence Mann, an attorney who helped draft the Federal Railroad Safety Act of 1970. Mann said states retain authority to regulate railroad safety until federal regulation covers the subject matter and described avenues under which states can act where federal rules are absent or do not fully subsume a safety subject. Railroad counsel countered with precedent and ICCTA-related preemption arguments. Committee members asked clarifying legal and factual questions; proposers and opponents both suggested technical amendments. The sponsors also proposed an amendment to revise train-length limits to 7,500 feet and to move detector spacing to 20 miles in some language under consideration.

Why it matters

AB 446 addresses safety at the intersection of state authority, federal oversight and private freight operations. If enacted, it would create new state standards and penalties affecting Class I and Class II carriers operating in Nevada and generate litigation risk under federal preemption doctrine if the courts find conflict with federal law.

What’s next

The bill drew intense, divided testimony. Stakeholders on both sides indicated a willingness to negotiate technical language, but the transcript showed no committee vote. Committee staff and members will continue discussions on statutory scope, preemption exposure and implementation details.

Quoted

- "As train lengths are varied below 7,500 feet, the incidences of mechanical failures resulting in train separations and derailments do not vary significantly. Once you increase train length above 7,500 feet, however, you see a corresponding increase in these occurrences," — Matthew Parker, Brotherhood of Locomotive Engineers and Trainmen.

- "Longer trains actually do enhance safety," — Peggy Igbuhay, Senior Director of Public Affairs, Union Pacific Railroad (company position).
