Railroad Brake, Signal, and Switch Operators and Locomotive Firers (Mid-Level) vs Signalling Tester In Charge / STIC (Mid-Level)
How do Railroad Brake, Signal, and Switch Operators and Locomotive Firers (Mid-Level) and Signalling Tester In Charge / STIC (Mid-Level) compare on AI displacement risk? Railroad Brake, Signal, and Switch Operators and Locomotive Firers (Mid-Level) scores 41.4/100 (YELLOW (Urgent)) while Signalling Tester In Charge / STIC (Mid-Level) scores 87.7/100 (GREEN (Stable)). Here's the full breakdown.
Railroad Brake, Signal, and Switch Operators and Locomotive Firers (Mid-Level): This occupation combines obsolete (locomotive firer) and declining (brake/signal/switch operator) roles. The physical yard work resists full automation, but Remote Control Locomotives, PTC, and automated inspection systems are displacing 40% of task time. Workforce shrinking (-19% since 2023), flat wages, no active hiring. Union and regulatory barriers provide moderate protection. Adapt within 2-5 years.
Signalling Tester In Charge / STIC (Mid-Level): Safety-critical physical testing in unstructured trackside environments, IRSE licensing, and personal go/no-go certification authority make this one of the most AI-resistant roles in rail engineering. Acute skills shortage and ETCS rollout sustain structural demand for decades. Safe for 15+ years.

Sub-Score Breakdown
Signalling Tester In Charge / STIC (Mid-Level) wins 5 of 5 dimensions — stronger on Task Resistance, Evidence Calibration, Barriers to Entry, Protective Principles, AI Growth Correlation.
| Dimension | Railroad Brake, Signal, and Switch Operators and Locomotive Firers (Mid-Level) | Signalling Tester In Charge / STIC (Mid-Level) |
|---|---|---|
| Task Resistance (/5) | 3.95 | 4.45 |
| Evidence Calibration (/10) | -3 | 9 |
| Barriers to Entry (/10) | 5 | 9 |
| Protective Principles (/9) | 4 | 7 |
| AI Growth Correlation (/2) | 0 | 1 |
What Do These Scores Mean?
Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk).
