Signalling Tester (Mid-Level) vs Train Guard / Conductor (UK) (Mid-Level)
How do Signalling Tester (Mid-Level) and Train Guard / Conductor (UK) (Mid-Level) compare on AI displacement risk? Signalling Tester (Mid-Level) scores 68.0/100 (GREEN (Stable)) while Train Guard / Conductor (UK) (Mid-Level) scores 46.2/100 (YELLOW (Urgent)). Here's the full breakdown.
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.
Train Guard / Conductor (UK) (Mid-Level): UK train guards face an existential structural threat that train drivers do not: Driver-Only Operation (DOO/DCO) is actively expanding across the network, with ~30% of UK rail journeys already operating without a guard. RMT union opposition is the primary barrier keeping guards on trains. Adapt within 3-5 years as DOO decisions by individual TOCs reshape the workforce.

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 Signalling Tester (Mid-Level) and Train Guard / Conductor (UK) (Mid-Level) role pages.
