House committee backs Railroad Safety Act requiring more wayside detectors and whistleblower protections

Representative Dean Hockman b Hill introduced House Bill 146 to the House Labor, Veterans and Military Affairs Committee, saying the measure "enacts the Railroad Safety Act, which mandates the use of wayside detector systems, requires reporting of railway safety violations, and prohibits retaliatory action, providing administrative penalties." The committee voted 9–1 to give the bill a do-pass recommendation.

The bill’s sponsor and expert witnesses told the committee the proposal has two main parts: a requirement that wayside detectors be installed and used at greater frequency along tracks and a prohibition on retaliatory actions when employees or others report safety violations. "Wayside detectors are the eyes of the railroad," said Clem Harris, an expert witness for the bill, describing the devices as tools that "watch for hot and failing wheel bearings ... sticking brakes" and other failure modes. Supporters cited the 2023 East Palestine, Ohio, derailment as an example of the consequences of missed warnings: "The overall cost to clean up the community has exceeded $1,000,000,000," Harris said.

Union and labor witnesses urged passage. Natalie Miller, Brotherhood of Locomotive Engineers and Trainmen national legislative representative, told members the bill would "keep our railroad crews, track workers, and communities in New Mexico safe" and said the measure is an "excellent start" toward stronger safety enforcement. Charlie Jeffcoat, a legislative representative for BLET Lodge 811, described long trains and the operational difficulty of inspecting cars and said closer detector spacing would speed identification of a failing axle so crews do not have to walk miles along a train to inspect equipment.

Railroad companies and business groups testified in opposition. Raquel Espinosa, public affairs director for Union Pacific Railroad, said the industry already deploys wayside detectors and that placement is driven by "science and data," adding "we must respectfully oppose this bill" because the proposal would impose fixed placement rules rather than site-specific placement the carriers currently use. Registered lobbyists for Union Pacific and BNSF told the committee that current practice spaces detectors roughly 25 miles apart and that the bill’s 10‑mile spacing is not based on a completed scientific study; BNSF’s representative said Colorado and Minnesota are studying the issue and the FRA has been engaged in related study.

Committee members questioned witnesses about where detectors already exist, who would pay for installation, and whether federal preemption applies. The sponsor and expert witnesses said installation costs would fall to the railroads "in satisfaction of state law," and emphasized they had tried to work with carriers during drafting. The expert witness said federal law is "silent on wayside detectors" and noted the Federal Railroad Administration (FRA) has conducted safety culture audits of Class I railroads that raised concerns about corporate responses to safety reviews.

After questions and public testimony, Representative Ortez moved a do-pass recommendation; Representative Johnson seconded the motion and the committee approved it 9–1. Representative Terrazas was the lone dissent; he said he wanted more scientific evidence about the optimal spacing ("10 miles, maybe 5, maybe 15").

What’s next: The committee’s do-pass recommendation advances HB146 to the next floor or calendar step where it will receive further hearings and possible amendments. Supporters asked the committee to retain the bill’s anti-retaliation provisions and the requirement for reporting and administrative penalties.
