Abstract :
Availability of the railway network is getting more and more crucial. This makes it increasingly important for maintenance contractors to prevent failures at the rail infrastructure that disturb the train service. In addition to this, improving maintenance efficiency remains an important point of interest. Monitoring crucial track objects is an indispensable tool in this context. To do so, Strukton Railinfra has developed its own monitoring system and has been using this within its services organisation since 1999. This system has now been developed into a universal monitoring shell around the objects of the track: POSS, the Preventive Maintenance and Failure Diagnosis System.
