ProRail manages an installed base which has an estimated replacement value of more than 30 billion euro. Tracks and turnouts are a significant part of the pie, amounting to more than 8 billion euro. Moreover, they consume more than
50% of total maintenance costs and 75% of renewal costs due to their usage-based, relatively rapid deterioration pattern and high cost of installation. Last but not least, track and turnouts, and especially high-speed turnouts are important because they are sources of failure and traffic disruption. This is why ProRail develops policy plans for track product and maintenance management.
