REDUCTION OF RAILWAY NOISE WITH COMPOSITE CONCRETE RAILS

The author describes how noise due to high speed trains can be greatly reduced by the use of a suitable track structure. A rail with increased stiffness and mass allows the use of much more flexible mountings than are possible with conventional rails. Vibration of the ground and track structure, the most difficult type of sound to handle, is isolated at source. The track will hold a more precise alignment longer, and demands on the foundation are less severe. The technique requires advances in concrete technology, but will make rail systems much quieter.
