Evolution of Track Geometric Quality in High-Speed Lines: Ten Years Experience of the Madrid-Seville Line
Track geometric quality on the Madrid-Seville high-speed line is the subject of this paper. An analysis is given of the deterioration process during the first ten years of the line’s commercial operation. The research explores the line’s maintenance operations and the available dynamic inspection records, which cover the line’s entire 471 km length. Regarding the inspection records, the analysis concentrates on vertical and transversal accelerations as measured on axle boxes, bogies, and vehicle bodies of Spanish high-speed trains (AVE). The research quantifies how track infrastructure (tunnels, viaducts, natural subgrade, embankments) influences geometric track quality deterioration. Also considered is the effect of switches and expansion devices on the deterioration process.
