Will AI Replace Locomotive Firers? The Quiet Decline of a Railroad Role
Locomotive firers face a 39% automation risk — moderate compared to many professions. But with only 1,600 jobs remaining and BLS projecting a -3% decline, the threat is not just AI. It is the slow disappearance of the role itself.
Only 1,600 people in the United States work as locomotive firers. That is not a typo.
This is one of the smallest occupations tracked by the Bureau of Labor Statistics, and it is getting smaller. BLS projects a -3% decline through 2034. [Fact] The automation risk sits at 39%, the overall AI exposure at just 26%, and yet the existential question for locomotive firers is not really about artificial intelligence. It is about whether the role has a future at all.
A Role Defined by Watchfulness
If you are not familiar with what locomotive firers do, here is the short version: they are the second set of eyes in the cab. They monitor locomotive gauges and warning systems (automation rate: 55%), watch for track obstructions and signal changes (30%), and assist with coupling and uncoupling operations (12%). [Fact] The job exists because operating a train carrying hazardous materials or hundreds of passengers demands redundancy — a human backup for the human engineer.
The highest-automation task is gauge monitoring at 55%. [Fact] Modern locomotives already feature sophisticated sensor suites that can detect anomalies in brake pressure, engine temperature, and fuel levels. AI-enhanced predictive maintenance systems can identify mechanical issues before they become emergencies. In many ways, the instruments already monitor themselves.
Track obstruction monitoring at 30% is harder to automate. [Fact] While LiDAR and camera systems are being deployed along major rail corridors, the variability of real-world conditions — weather, wildlife, debris, construction zones — means human visual confirmation remains important. Computer vision is improving rapidly, but the consequences of a miss are measured in lives.
Coupling and uncoupling at 12% is deeply physical work. [Fact] This is hands-on railyard labor that AI has almost no path to automating in the near term.
The Real Threat Is Not AI — It Is Obsolescence
Here is where the locomotive firer story diverges from most AI-and-jobs narratives. The biggest risk to this occupation is not that AI will replace firers. It is that railroad companies and regulators will decide the role is no longer necessary.
The debate over crew size has been raging in the U.S. railroad industry for years. Freight railroads have pushed to reduce train crews from two people to one, arguing that modern safety technology makes a second crew member redundant. Unions have fought back, citing safety concerns. [Claim] The outcome of this regulatory battle will determine the future of locomotive firers far more decisively than any AI advancement.
The median salary is $61,740, which is solid for a role that typically does not require a college degree. [Fact] But with only 1,600 positions nationwide and a declining trajectory, new entrants face a challenging job market regardless of AI.
By 2028, overall exposure is projected to reach 41% with automation risk climbing to 54%. [Estimate] That is a significant increase from today's 26% exposure, driven primarily by advances in autonomous train technology and sensor-based monitoring systems.
Autonomous Trains Are the Real Wildcard
While current AI exposure is low, the technology pipeline tells a different story. Several countries are already testing or deploying autonomous freight trains. Australia's Rio Tinto has operated autonomous trains in the Pilbara region since 2018. [Fact] In Europe, pilot programs for autonomous rail operations are advancing. The technology exists — the barriers are regulatory and labor-political, not technical.
If the U.S. moves toward autonomous or single-operator freight trains, the locomotive firer role does not gradually shrink. It disappears. This is not an AI-augmentation story where workers learn new tools. It is a displacement story where the entire position is eliminated.
What This Means If You Are a Locomotive Firer
The honest advice is to plan for transition. If you are early in your career, the path forward likely runs through locomotive engineer certification — moving from the support role to the primary operator role. Engineers face their own automation pressures, but the timeline for full autonomous operation in the U.S. is measured in decades, not years.
If you are mid-career, the union advocacy around crew size requirements is genuinely important. Engage with it. The regulatory framework will shape your career trajectory more than any technology advancement in the short term.
And regardless of where you are, the skills that transfer — equipment monitoring, safety compliance, situational awareness — are valued across the broader transportation sector.
