Ride atop cars that have been shunted, and turn handwheels to control speeds or stop cars at specified positions.

“Ride atop cars that have been shunted, and turn handwheels to control speeds or stop cars at specified positions.” is a supplemental task performed by Railroad Brake, Signal, and Switch Operators and Locomotive Firers. Among the occupation's 28 rated tasks, workers place it 9th by importance (#20 most important). About 38% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T0.
