New technologies applied to railway maintenance

As a result, it may be eventually required to modify the maintenance process to reconsider
the execution of corrective tasks in order to keep the vehicle in operation as per the joint
evaluation of the predictive model and the real-time reported alerts and events.

At present it is possible to diagnose the condition of a good number of rolling stock and
infrastructure equipment, for which predictive algorithms are being developed to adapt the
maintenance strategy and ease operational decisions, including:

• Wear of brake pads and brakediscs

• Wear and detection of defects in pantograph contacttrips
• Wheel profile scan to identify defects, and determine the limits ofuse
• Missing or incorrect positioning of exterior elements: fairings, doors,etc.
• Axle-box and motor bearings condition.

• Components diagnosis in main equipment: Traction, Brake, Doors, Train ControlSystem
• Operating condition of PointMachines
