Abstract
In this paper, the potential of an already existing measurement system for the condition assessment of insulated rail joints is shown. The system properties of the so-called rail surface measurement system are described and the potential of systematic data analysis is addressed. The measured short-wave range and the high sampling rate offer the possibility of adding further facets to the existing track condition assessment. The data source is particularly suitable for evaluating short-wave effects, which were previously difficult to describe. With the help of a positioning algorithm it becomes possible to evaluate isolated rail joints regarding their quality development over time. It can be shown that insulated rail joints deteriorate in a super linear manner. In order to reduce the negative influence on the quality behaviour of the entire track, intervention thresholds for a preventive maintenance regime have to be defined. Using technical-economic assessments, these intervention thresholds can be defined in a way to ensure undisturbed railway operation with the lowest possible life cycle costs.
