1 CDM-POROTRACK? allows the vibration isolation performance to be tuned by changing the stiffness of the CDMISO- SRS resilient railstrip under the rail

2 Considerable reduction of the re-radiated noise

3 The continuous support of the rail, combined with the CDMISO- POROTRACK? system guarantees a uniform elasticy in the length direction of the track, thus prolonging the life of the rail and minimising corrugation

4 Constant geometry, even after many years of intensive use

5 Considerable savings due to reduced construction height and weight (e.g. tunnels and bridges)

6 Low maintenance
