This paper describes a computerized decision support system that integrates robust track degradation models, calibrated and validated with more than ten years of historical data from inspections in the Portuguese railway network, to support railway track maintenance and renewal decisions. Furthermore the software tool incorporates a data management module that facilitates the assessment of track component conditions. In this paper we present the methodology and the results from the data mining analysis on the track geometry parameters and some important automatic outputs of railway track condition and maintenance, and renewal forecasts that are integrated in this decision support system. The developed software proved to be a useful tool for track managers and engineers to analyze the railway track condition and decide when maintenance is necessary and when is the best time for renewal of railway track components.
