High speed and track deterioration: The role of vertical stiffness of the track

Andrés López Pita, Paulo Fonseca Teixeira, Francesc Robusté

Open publisher page 109 citations

Abstract

The aims of this article are as follows. Firstly, the importance of vertical track stiffness on high-speed lines is emphasized. Secondly, it proposes an optimum range for this vertical stiffness value, establishing parallel equations that enable the influence of every elastic component located under the rail to be quantified (base plates, ballast and subgrade) in total track stiffness. Finally, a range of variations is proposed for base-plate vertical stiffness.
