Will AI replace Signal and Track Switch Repairers?

What this score means

Signal and Track Switch Repairers is among the least exposed roles in Construction & Trades. Most of what the job involves still sits outside what current AI can do, even as the tools around it keep changing. At 11 out of 100 it scores 3 points below the Construction & Trades average of 14. Across the 3 sources behind this baseline, individual estimates run from 5 to 20, so the score is a weighted consensus rather than any single figure.

The number is a consensus estimate for the typical version of the role, built from published academic and industry research scored occupation by occupation. It is not a prediction about any individual. How scoring works
