Elastic Rail Pads and Base Plate Pads for High-Speed Traffic and Conventional Lines

Our rail pads and base plate pads reduce any vibrations and structureborne sound produced in modern track bed structures. The perfect emission protection for your projects.

Reduce High Stress Loads with Elastomers

When trains travel past, they cause vibrations and structure-borne sound due to the moved load, rough surfaces on wheels and rails, and local oscillations in the track assembly stability. In such cases, highfrequency impacts are primarily due to vehicle and track system interactions (discrepancies in wheel ovality, ripples, incorrect track positions, rail corrugations and similar) while low-frequency impacts are caused by wheelset loads, travel speed, and carriage, axle and bogie gaps.

This largely characterises the load on the overall system. Using highly elastic materials such as special microcellular EPDM, natural rubber and CR composite materials in vibration-optimised bed structure shapes can efficiently limit vibrations entering the sub-structure on a permanent basis.

Cost Reduction and Track Bed Structure Protection Using Rail Pads and Base Plate Pads

Our elastomer bearings for track fastening systems optimally meet the requirements of modern railway tracks on a permanent basis. Featuring our highly elastic elastomers made of microcellular EPDM and with a very wide spring rigidity range to minimise structure-borne sound from track vibrations, our products help to greatly reduce loads in track bed structures. This protects the overall track structure system, thus reducing our clients’ costs for maintenance and repair immensely.

Installing elastic or highly elastic rail pads and base plate pads in special fastening systems makes use of the load transmission in rails. The acting forces are distributed across several support points in the triggered wheel load, so that the stress on the directly affected rail support point is greatly reduced.

Noise is also produced by factors such as friction resistance, uneven surfaces, ripples and rail corrugations and by the related vibrations caused by trains passing over. Noise is reduced to a minimum if the railway vehicle and railway lines are in good working order. Using elastic rail pads greatly reduces the impact of high-frequency vibrations transmitted into the ballast bed through the rail and sleeper. This counteracts shattering of ballast.
