Transition zones
Balance out stiffness variations and reduce wear on superstructure components
When changing from one type of superstructure to another, the components come under great stress because of variations in the stiffness. This increases the amount of maintenance required. Solutions offered by Getzner help to significantly reduce the stresses in transitions and the resulting maintenance costs.
Problems
- Ballast destruction - White Spots
- Reduced passenger comfort
- Sudden variation in stiffness
- Protection of structures
- High rate of superstructure component wear
- High level of maintenance
- High life cycle costs
- Lower route availability
Solution
Installing elastic elements reduces the shock loads and the vibrations that are transferred as the train passes. The defined use of highly elastic Sylomer® and Sylodyn® components compensates for the undefined variations in stiffness in the transition area.
- Reduction of ballast contact pressure
- Ballast protection and improvement in track geometry
- Lower maintenance costs
- Optimization of track elasticity reduces variations in stiffness and ensures a smoother passage
- Lower maintenance costs
- Optimized load distribution through elongation of the bending line of the rail
- Reduction in dynamic forces
