The European rail network is getting more and more important in the transportation sector: it hosts high speed-trains, higher loads of more passengers or goods, with increased frequency. This determines a higher mechanical load for the moving parts of the carrier involved: therefore, increasing inspection and maintenance are required in order to guarantee safety and well-being of trains.

One of the biggest concerns about transportation safety is broken wheels due to internal cracks. Frequent accidents and regular breakdowns have been registered in the latest years due to this failure.

Trainwheels face the challenge of optimizing thermography in order to use it as an automated train wheel crack detection method, meeting all European SafetyStandards. Using thermography for train inspection would result in a big improvement compared to previously quoted methods: thermography is an automated and faster approach; it is as well cleaner and cheaper.

Our aim is to improve train circulation safety by enhancing the effectiveness of non destructive tests on wheels, in order to identify cracks as soon as possible.
