Questions about railroad brake, signal, and switch operators and locomotive firers and AI

Will AI replace railroad brake, signal, and switch operators and locomotive firers?

Unlikely. Most of the work is hard for today's AI to speed up. Railroad Brake, Signal, and Switch Operators and Locomotive Firers score 17 out of 100 (low exposure), #663 of 923 US jobs. AI could speed up 7 of the job's 28 tasks, 3 of them on its own, while 21 see little or no speed-up. Exposure means the work is likely to change, not that the job will disappear.

Which railroad brake, signal, and switch operators and locomotive firers tasks can AI do?

The most exposed tasks include "Receive oral or written instructions from yardmasters or yard conductors indicating track assignments and cars to be switched"; "Record numbers of cars available, numbers of cars sent to repair stations, and types of service needed"; "Answer questions from passengers concerning train rules, stations, and timetable information".

Which railroad brake, signal, and switch operators and locomotive firers tasks are hardest for AI?

Tasks with little or no AI speed-up include "Observe train signals along routes and verify their meanings for engineers"; "Signal locomotive engineers to start or stop trains when coupling or uncoupling cars, using hand signals, lanterns, or radio communication"; "Pull or push track switches to reroute cars".

Are people already using AI for this work?

Not much yet. None of the job's tasks showed up in real conversations with Claude in April–May 2026, according to the Anthropic Economic Index.

How many people work as railroad brake, signal, and switch operators and locomotive firers, and what do they earn?

About 12,400 people in the US, with median pay of $68,840 a year (BLS, May 2025).

How to read this score. Exposure measures how much of the work AI could speed up, not whether the job will disappear. A highly exposed job can change shape, with people spending less time on routine tasks and more on the rest. The score counts tasks AI can speed up on its own in full, and tasks that need extra software at half weight.

The ratings come from published research based on GPT-4 (2023). To show what's happening now, each task is also checked against the latest Anthropic Economic Index, which records which tasks people actually use AI for. That data is refreshed automatically when Anthropic publishes a new release. Read the full method.
