Infrastructure Protection

As the major component of each railway, the rails have to be observed with exceptional attention. Each maintenance has to be planned with a vast amount of preliminary work. Unplanned maintenance as well as accidents causes a lot of additional effort since neither the manpower is available, nor the train schedule is adapted. Hence, such an unplanned incident is accompanied by a lot of extraordinary issues. For the customer it means in the best cases train delay or even worse cancellation of service.
As a serious danger for rail vehicles derailed wheels cause considerable damage to railway infrastructure. The DRD is designed to detect derailed wheels and informs the dispatcher instantly.
