Will AI replace locomotive engineers?

Some tasks are already being done by AI or machines; the rest still needs a person. About 3h 20m of a typical shift is made up of tasks that AI or robots have done on their own in real use somewhere. That doesn't mean those hours are automated in a typical workplace. The other 4h 40m (58%) stays with people. Separately, BLS expects about 0.5% more of these jobs by 2035 (all jobs: +3.5%).

None of this job's tasks show regular AI use yet. That can mean the work is hands-on or in person, or simply that it rarely comes up in AI usage data.

For some tasks, yes. Robots have done 3 of this job's tasks in workplaces like this one, about 3h 20m of a typical shift. 1 more task has only been done in factory setups built around the machine, so it stays with people here. For 2 physical tasks, no robot has shown it can do the work yet.

• Operate locomotives to transport freight or passengers between stations or to assemble or disassemble trains within rail yards. (1h 46m a shift; e.g. AutoHaul (Rio Tinto / Hitachi Rail STS), in use)
• Receive starting signals from conductors and use controls such as throttles or air brakes to drive electric, diesel-electric, steam, or gas turbine-electric locomotives. (1h 24m a shift; e.g. AutoHaul (Rio Tinto / Hitachi Rail STS, Wabtec onboard controller), in use)
• Inspect locomotives after runs to detect damaged or defective equipment. (11m a shift; e.g. E-Check (camera arch + MUFIG mobile underfloor unit + E-Check cobots), in use)

4h 40m of a typical shift, or 58%, goes to tasks with no AI or robot evidence yet. No AI usage or robot deployment has shown up for these so far. The biggest:

• Observe tracks to detect obstructions. (1h 3m a shift)
• Interpret train orders, signals, or railroad rules and regulations that govern the operation of locomotives. (53m a shift)
• Confer with conductors or traffic control center personnel via radiophones to issue or receive information concerning stops, delays, or oncoming trains. (42m a shift)
• Monitor gauges or meters that measure speed, amperage, battery charge, or air pressure in brake lines or in main reservoirs. (42m a shift)
• Inspect locomotives to verify adequate fuel, sand, water, or other supplies before each run or to check for mechanical problems. (21m a shift)

Much of it comes down to where and how the work happens. In-person, hands-on and high-stakes work is where AI and robots have made the least headway so far. In the official O*NET survey of people in this job:

• 100% carry high or very high responsibility for other workers' safety
• 89% use their hands on tools, objects or controls more than half the time
• 85% work in very hot or cold conditions at least weekly

The median pay is about $81,410 a year ($39.14 an hour), 60% above the median for all U.S. jobs ($50,980). Most people in this job earn between $60,680 and $109,220 a year; that range covers the middle 80%. Pay figures are from BLS, May 2025, and vary a lot by state and employer. Pick a state to compare:

BLS projects growth of 0.5% from 2025 to 2035, compared with 3.5% growth for all jobs. That's about 28,000 jobs in 2035. It expects about 2,000 openings a year, mostly from people retiring or changing careers. These projections don't single out AI as a cause.

About 33,000 people in the U.S., roughly 0.02% of all workers (BLS, May 2025). That makes it the 458th largest of the 796 jobs on this site. BLS expects about 28,000 in 2035.

The most common requirement is a high school diploma: about 68% of people in the job said so in the official O*NET survey. O*NET rates the job at level 2 of 5 for preparation, which usually means: high school diploma, some training. Requirements vary by state and employer, especially for licensed work.

These come from the job's official skill ratings and from the tasks that AI and robots touch least today. Building them keeps you strong in the parts of the work that still need a person:

• Skills that matter more here than in most jobs: Operation and Control, Operations Monitoring, Monitoring, Active Listening
• Get strong at the parts of the job that stay with people (listed above), which take 4h 40m of a typical shift
• Tools employers list: Microsoft Excel, Microsoft Word

These use similar skills. Matches come from 109 official ratings of skills, knowledge and work activities, and each needs the same or less preparation unless the official list relates the jobs directly:

• Railroad Brake, Signal, and Switch Operators and Locomotive Firers (1h 4m touched, $69k median pay)
• Rail Yard Engineers, Dinkey Operators, and Hostlers (3h 38m touched, $61k median pay)
• Subway and Streetcar Operators (5h 40m touched, $86k median pay)

Each task carries its own evidence label. For this job: 3 with robots in real deployments, 11 with no AI or robot evidence found. The minutes per task are estimates, not measured hours, and "no evidence" doesn't prove a task is safe.
