Analysis of rail defect detection methods

Seeking to optimise maintenance costs, RATP questioned whether retaining track circuit technology remained justified.

The study offers a comparative review of the rail monitoring and defect detection methods used by other railway networks.

It concludes that economically viable techniques now exist to identify the most frequent and most critical rail defects reliably and proactively. Deploying these systems, combined with appropriate maintenance strategies, keeps the risk of rail breakage within acceptable limits without recourse to traditional track circuit technology.
