Signalling Tester In Charge / STIC (Mid-Level) vs Train Guard / Conductor (Mid-Level)
How do Signalling Tester In Charge / STIC (Mid-Level) and Train Guard / Conductor (Mid-Level) compare on AI displacement risk? Signalling Tester In Charge / STIC (Mid-Level) scores 87.7/100 (GREEN (Stable)) while Train Guard / Conductor (Mid-Level) scores 44.3/100 (YELLOW (Urgent)). Here's the full breakdown.
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.
Train Guard / Conductor (Mid-Level): UK train guards face a genuine existential question: Driver Only Operation (DOO) is expanding across TOCs, the East West Rail DOO dispute crystallises the threat, and automated ticketing erodes revenue protection work. Strong RMT union resistance and physical safety requirements buy time, but the role's long-term trajectory points toward reduction rather than growth. Adapt within 2-5 years.

| AI Growth Correlation (/2) | 1 | 0 |
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).
