Predictive maintenance across track, signaling, and rolling-stock assets on a regional network
Segment: Predictive maintenance for rail infrastructure
With track, signaling, and rolling-stock assets spread across a regional network, a maintenance team typically has sensor data and inspection records but no way to combine them into a single, ranked view of where risk is concentrated. Fixed inspection cycles catch some issues early and miss others between visits; reactive callouts after a reported fault mean some disruptions are unplanned by definition. Budgeting for intervention — inspection, light repair, or full replacement — ends up happening case by case rather than as a forward plan.
How the deployment was structured
One risk score per asset
Real-time sensor readings and historical maintenance records combine into a per-asset failure-probability score, ranked by urgency and safety impact, replacing separate fixed-cycle and reactive tracks.
Risk scores become work orders
Risk rankings translate directly into optimised maintenance schedules, balanced against safety thresholds, crew availability, and possession windows.
Network-wide visibility
A spatial view of degradation across the whole network flags at-risk clusters before they cascade into service disruptions — visible before any single asset fails.
Intervention level recommended in advance
The system recommends inspection, light repair, or full replacement weeks ahead, giving budget and contractor scheduling real lead time instead of a reactive callout.
Replacing fixed cycles and reactive callouts with one ranked, network-wide risk queue is what lets an operator plan interventions weeks ahead instead of finding out about a failing asset from a fault report.
