Switches (turnouts/points) and crossings are vulnerable nerve centres of railway infrastructure and are main cost-drivers. Their maintenance is highly costly for the infrastructure management. Switch-defects, -failures and train-derailments, on account of defective switches, disturb the traffic flow in a high extend. Switch and turnout machine failures account for a large proportion of infrastructure related delays and unplanned maintenances.
Fixed Infrastructure Asset Monitoring enables tracing defects in turnouts. This will be done by means of intelligent software. Thanks to the comparison of actual and reference values the software can detect imminent failures even before a malfunction occurs. Depending of these values/data maintenance messages will be generated and send to the competent authorities automatically. Thus failures can be avoided by means of PREVENTIVE MAINTENANCE.
