THE RHEDA 2000 BALLASTLESS TRACK SYSTEM

Hugo Bachmann, Walter H. Mohr, Mateusz Kowalski

Open publisher page 9 citations

Abstract

The demands of advanced high-speed rail traffic subject ballasted track systems to conditions that reach their load limits, resulting in redistribution of ballast stones and impairment of track positioning. The RHEDA 2000 ballastless track system is described. Prestressed concrete sleepers form a monolithic unity with the concrete bed, enclosing the sleepers to the sides. The system was installed for the first time on a 8000-m section of the railway line between Erfurt and Halle-Leipzig in Germany. The installation procedure is outlined. Two methods were used to provide precise adjustment of the track: portal adjustment and spreader-bar adjustment. The method for placing the concrete on the track is described. The use of RHEDA 2000 for the high-speed Dutch line HSL-Zuid is described.
