20. Conclusions
 Current asset inventory and diagnostic services are increasing data
availability, variety and quality
 Data is only part of the story
 Examples of improvements:
 Increased accuracy in localisation/avoiding ambiguity
 Get an objective list of assets
 Verify and measure assets from the office
 Recommend and Prioritize Maintenance & Renewal Works
 Railways should take advantages of these new capabilities
