Abstract

This paper examines the strategic use of the Track Quality Index (TQI) in railway track maintenance, particularly focusing on decision support systems that are based on performance indicators. The research illustrates how aggregated TQI values and percentile-based indicators can be utilized to assess the overall health of the network, identify critical sections, and support long-term maintenance strategies. The study highlights that, in addition to aggregated indicators, analyzing individual geometric parameters is essential for determining suitable maintenance interventions. Furthermore, the paper proposes a multi-level TQI/KPI-based decision support framework, aligning with the EN 13848-6 standard and enhancing decision-making in modern asset management for track maintenance.
