THE REQUIREMENTS OF THE RAILWAY AND ITS FURTHER DEVELOPMENT FOR HIGHER SPEEDS AND AXLE LOADS

BEANSPRUCHUNG DES EISENBAHNOBERBAUES UNE SEINE WEITERENTWICKLUNG FUR HOHERE GESCHWINDIGKEITEN UND ACHSLASTEN

Constant research has been conducted in the permanent way with the rails, ties, ballast bed and the underneath ground structure for improvements to cope with the increasing axle loads and higher speeds. This article considers the more sophisticated concrete rail bed structure. The conclusions are as follows: The present ballasted rail structure with rails of 90 kp per mm (super 2) is suitable for axle loadings of 25 to 28 tons, at present speeds. With rails of 110 kp/mm (super 2) and weight per meter of 70 kg, the axle loading can be increased to 37 to 42 tons. However, the ballast bed must be strengthened. For speeds greater than 220 to 250 km/h, there will need to be new developments for the railroad track structure. Because the present ballasted right of way would require too much maintenance under such conditions. The concrete rail bed for urban railways has a potential for effecting substantial savings in track maintenance costs, thereby reducing the over all cost of the track structure.
