Platform Attendant (Mid-Level) vs Signalling Tester (Mid-Level)
How do Platform Attendant (Mid-Level) and Signalling Tester (Mid-Level) compare on AI displacement risk? Platform Attendant (Mid-Level) scores 46.3/100 (YELLOW (Moderate)) while Signalling Tester (Mid-Level) scores 68.0/100 (GREEN (Stable)). Here's the full breakdown.
Platform Attendant (Mid-Level): Platform attendants are protected by irreducible safety duties at the platform-train interface, strong union representation (RMT, TSSA, ATU), and physical presence requirements in unpredictable station environments. But automated announcements, ticket barriers, and CCTV monitoring are steadily absorbing information and revenue protection tasks. Adapt within 3-7 years.
Signalling Tester (Mid-Level): IRSE-licensed safety-critical testing on live railway infrastructure in unstructured trackside environments makes this role deeply AI-resistant. Mandatory human sign-off on interlocking and functional tests, acute UK skills shortage, and ETCS migration demand protect the role. Safe for 10+ years.

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). For full individual assessments, see the Platform Attendant (Mid-Level) and Signalling Tester (Mid-Level) role pages.
