Solution for stiffness variations in the railway superstructure

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 deterioration - White Spots
Reduced travelling comfort
Stiffness leap
Protection of buildings
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
Decreased deterioration rate
Long-lasting and consistently high quality of track geometry
Optimization of track elasticity reduces rail corrugation and leads to a quality improvement of the wheel-rail interaction
Optimized load distribution through elongation of bending line of the rail
Reduction of dynamic forces
