Multi-applicable track system for trams
edilon)(sedra SDS (Sound Damping System) is a cost effective, electrical insulating, vibration attenuation and airborne noise reducing solution for light rail and in particular tramway applications. The system optimally meets the needs of modern tram networks, with many areas of application.
The potential for urban mobility is increasing across the world, and with it the need for environmentally friendly and reliable transportation systems. In addition to “in street” track, grass track have also become increasingly popular in recent years.
edilon)(sedra SDS is designed for optimum integration in various application fields such as in-street running track, grass track, depots, switches and crossings, and level crossings.

Adaptable for different elasticity’s
The versatile system is easy and quick to install and offers both, the traditonal Bottom-Up as well as the cost-efficient Top Down, installation methods. edilon)(sedra SDS can be adapted to different elasticities and can also, for special track applications and demands, be factory-prepared to fit rectangular or round shape gauge bars and rail anchors.
The applied edilon)(sedra filler blocks are not only made of recycled material, but are also 100% recyclable. The easy-to-install filler block system can be adjusted to different elasticities.
Why opt for SDS
- High noise and vibration damping
- Modular & easy to install
- Good stray current control
- Wide spectrum of application
- 100% recyclable components

edilon)(sedra SDS Grass Tracks
Onwards to a greener world!
SDS has several applications, and is not limited to “in street” tram tracks. In recent years, we have seen grass tracks become increasingly popular as well!
SDS grass tracks do not only look attractive, they also provide additional green spaces in the city, with all of the benefits that brings in terms of health and well-being. SDS has good insulating properties and thus removes uncertainties about stray currents in grass tracks. Combined with Editack Spray, you can realize a level of insulation that is far above the current standard.
