Track Condition Measurements & Maintenance

Together wit PC Soft GmbH we offer an integrated solution for the assessment and analysis of track conditions. The obtained measurements can be processed directly within the zedas®asset Application Lifecycle Management System. Subsequently, optimised maintenance activities can be derived based on the recorded data. This mobile data acquisition of track conditions ensures high infrastructure availability at comparatively low costs.
