Internal Rail Flaw

Internal Rail Flaw

The ever-rising need to internally inspect the rail at high speed to avoid track possession and integrate it with high speed contact less technologies overcoming actual technologies limitations.

Vision systems can't simply do everything. Some of the most insidious defects develop within the rail. The full infrastructure assessment can be performed only including these internal flaws with the most advanced ultrasonic technology.

Ultrasonic Inspection

The Rail Flaw inspection system is based on a structure, which is connected to a dedicated boogie attached to the inspection vehicle. The mechanical interface holds all the transducer holders. This mechanical module is designed to keep the transducers in contact with the rail providing them with the required parameters to ensure proper coupling. The mechanical design is vital to keep such contact conditions while tracking the track route, so that the system will be able to inspect the track at speeds up to 100 Km/h (dependent on track surface and geometry conditions).
