Prorail is the infrastructure manager of the Dutch Railway network. In the future we want to increase railway traffic without building new tracks. We expect to achieve this by making a shift to condition based and predictive maintenance. Monitoring data, storing and getting it to all parties involved is crucial in this process. This presentation discuss about how ProRail developed the ProRail Monitoring Platform (PMP) and how it meets the needs of the different end users involved in maintaining our railway network.
