Rail operators already keep strong records and apply consistent standards. The opportunity is to make body inspection faster and more thorough, measure defects more precisely, and capture an even richer condition record on every pass.
Walking every carriage by hand consumes valuable turnaround time and creates scheduling pressure at peak periods.
Covering every panel, seal and fixing to the same standard, every time, is hard to sustain when turnaround windows are tight.
Subtle changes like panel deformation or door alignment are hard to measure precisely and repeatably by hand.
Records are already good. Adding consistent photographic and measured evidence on every pass makes defect trending and history stronger still.
Inspection data is captured by either an autonomous inspection robot or smart sensor payloads, imaging the full exterior of the rolling stock.
The captured data is uploaded to NXTGEN Inspect, where AI analyses it and classifies defects such as graffiti, panel dents, scratches, window damage, door misalignment and coupling anomalies.
An inspector reviews the AI findings and confirms, flags or dismisses each one, so every defect that reaches a report is verified.
Structured condition reports are generated per vehicle, with annotated imagery and maintenance priorities, ready to act on.
New graffiti identified on any exterior surface, with location annotated and size estimated for remediation scheduling
Impact damage, surface scratches, and panel deformation across carriage exterior panels and corners
Cracked, scratched, or broken windows and window seal failures across all carriages
Door misalignment, gap anomalies, and seal failures that may affect passenger safety or service compliance
Visible coupling damage, misalignment, or foreign object entanglement at inter-carriage connections
Missing, damaged, or obscured exterior lighting, route indicators, and mandatory signage panels
Every passing train is fully inspected in under 30 seconds, with no technician involvement required for the initial defect pass.
The same detection criteria applied to every train, regardless of shift, time of day, or workload pressure.
A photographic record of every train body at every inspection, enabling condition trend tracking and warranty claims.
Automatic maintenance notifications with annotated imagery reduce the time from defect detection to workshop scheduling.
