RAILROAD TRACK STRUCTURE FOR HIGH SPEED LINES

Speeds in the 250-300 km/h range demand a track with precise alignment with elastically mounted rails, and low maintenance cost. Along with an improved ballasted track, a track structure mounted on a rigid pavement, distinguished by a precise mounting of the rails and the promise of low maintenance cost, was discussed. Prof. Eisenmann described a track structure using a concrete paving slab. The results presented were based on research carried out at the Institute for Construction of Land Transport Routes of the Technical University of Munich. On the basis of research work of the last two decades and current practical experience, it has been determined that a reinforced ballasted track may be used for speeds up to 250 km/h. For higher speeds an elastic rail mounting on a rigid pavement has been investigated. Experiments performed on the high-speed section of the Deutsche Bundesbahn between Bielefeld and Hamm using concrete ties demonstrated a noticable improvement with the insertion of a soft rubber pad in the area of the rail fastening. Experience in highway construction indicates the pavement should have a multi-layered structure, and the supporting system must be frostproof. With a correct calculation of dimensions and structural design, ideal conditions are created for trouble-free wheel motion with an almost complete elimination of maintenance work.
