Condition Monitoring Purpose

�Safety

Generate early warning to operational staff

about pending failures of both rolling stock

and infrastructure

�Efficiency

Provide condition information about the

assets to maintenance in order to support

effective maintenance methodologies (i.e.

condition based maintenance)

�Management & Business information

Improve utilization of assets,

and recover lost revenue
