Railroad track fixing systems

Extending performance, enabling lower maintenance costs

DSM contributes to railroad safety and efficiency by delivering materials that perform better than alternatives. Together with customers we help build durable solutions for transport systems of today.

Concrete sleepers, the preferred environmental option to hard wood sleepers, needs energy to be absorbed when the train passes otherwise premature failure can occur in the sleeper due to vibration fatigue in the concrete. Elastomeric pads placed between the rail and the concrete provide this energy absorption.

Arnitel® outperforms alternative materials used in pads. Its superior performance over a wide temperature range, resistance to chemicals and fatigue allows Arnitel pads to last twice as long as any other material. The total cost of use is reduced as rail maintenance costs are cut dramatically.

DSM is an experienced, long term supplier of materials for fixing pads in many countries. We understand the engineering needs and specifications of different railroad operators that define the requirements on fixing pads. Over many years, we have helped customers optimize part design using CAE and joint testing programs, and our recommendations help to ensure theat the required stiffness is obtained and the clamping forces maintained
