See condition changing before the failure becomes obvious.

Condition monitoring is useful when the railway needs more than a one-time inspection. Repeated measurements can show which vehicles or locations are changing and deserve attention.

In practice: watch how the railway behaves over time, then send technicians only where the data says something is changing.

Wayside wheel-condition screening using acceleration-based measurement.

Best for: finding vehicles that deserve closer wheel inspection

Onboard wheel-rail interaction diagnostics over repeated routes.

Best for: seeing dynamic behaviour and recurring locations

Measure vibration responses from the vehicle as it runs.

Best for: track-condition and interaction screening

Measure unstable lateral vehicle behaviour.

Best for: vehicle dynamic investigation

Organize repeated diagnostic data into condition history.

Best for: turning measurements into maintenance priorities

Collect the same type of condition signal over time.

Know exactly where and on which asset the signal occurred.

Look for trends, anomalies or recurring hotspots.

Use detailed inspection after the monitoring system gives a reason.

Monitoring is valuable when it reduces blind inspection effort and creates an earlier trigger for targeted maintenance.

Before: condition is known only when somebody inspects the asset.

After: maintenance can see which assets are changing between inspections.

CBP defines the condition question, chooses the IVM or DMA route, structures data ownership and reporting, and connects the monitoring output to a real maintenance action.
