STRAILastic track damping system
Smart track damping for light rail, trams & more
STRAILastic delivers smart, engineered solutions for rail insulation, track damping, and greening. Specifically designed for urban environments, grooved rails, and public transport infrastructure, our systems effectively reduce structure-borne noise and vibrations while isolating stray currents, making a key contribution to noise reduction in rail construction. STRAILastic track damping systems are compatible with all common track superstructures and are used in both sleeper-track and continuously supported rail designs. They impress with rapid installation, minimal maintenance requirements, and high-quality, long-lasting materials that have been thoroughly tested.

STRAILastic green track: Fast setup, flawless insulation
During the refurbishment of Munich’s Tram Line 25, Stadtwerke München installed 1,880 meters of green track. Discover how the STRAILastic_R profile not only met the stringent requirements for stray current insulation, but also, thanks to its quick and easy installation, helped the project reach completion ahead of schedule.
Complex track refurbishment with the STRAILastic track damping system
A successful track refurbishment in Ulm: Our STRAILastic_SOK_simplex was seamlessly installed despite an 8 % descending gradient, a curve, and an underpass. A testament to maximum flexibility and performance under the toughest conditions.
The advantages of STRAILastic track damping systems
Advantages for cities, construction companies and planners
STRAILastic solutions for damping vibrations in track construction use precisely fitting chamber filling elements made of vulcanized rubber, installed up to the top of the rail (SOK). These elements replace traditional high-maintenance joint grouting systems, saving time and reducing long-term maintenance costs—especially on heavily trafficked urban routes.
Our track damping systems feature a modular design and can be adapted to various track superstructures, regardless of sleeper type or fastening spacing. The SOK system is ideal for single-support and sleeper-track constructions, while the SOK simplex system was specifically developed for continuously supported rails.
The STRAILastic track frame support (GRS) further enhances efficiency, allowing the entire track frame to be quickly fixed in height and position. This enables load-bearing concrete slabs and filling concrete to be placed continuously, eliminating the need for traditional underpouring. As a result, construction times are significantly reduced, which also lowers overall project costs.
Advantages for inner-city infrastructure and noise-sensitive zones
In densely built-up urban environments, effective and cost-efficient track damping is essential. STRAILastic systems are specifically designed to meet these demands. They provide significant noise reduction through elastic elements and effectively minimize vibrations and structure-borne noise, while offering excellent long-term stability and weather resistance.
STRAILastic solutions are particularly effective for tram tracks, thanks to their minimal maintenance requirements and flexible integration into existing track layouts. This makes them ideal for intersections, inner-city routes, or complex track geometries—situations where traditional joint sealing often falls short.
Whether for track damping in city centers, new construction projects, or the refurbishment of light rail tracks, STRAILastic delivers modular, robust, and economical track damping systems that perform reliably today and in the future.
