Urban transports, such as trams and undergrounds railways, increase the level of acoustic pollution that directly affects cities and living areas. Whisper Acoustics has developed the Protrack range to provide some solutions for coating the rails with special profiles produced from high density SBR/EPDM regenerated rubber that allow the mitigation of the produced vibrations.
The elasticity of the profile assures an excellent mechanical junction between the rail and railbed, markedly reducing the rail track maintenance.
The Protrack line profiles are available for any type of rail and are supplied in 0.75 to 1.5 meter length bars.
The "Protrack Set" line guarantees the structural fixing of the rail to the concrete slab, thanks to the special "wrapping" profiles, it is so an alternative system to the classic mechanical fixing. This system assures an efficient insulating from vibrations produced by the track and assures the electric insulation of the rail; moreover in this case the efficient junction between track and connecting pavement extends the track's life.
These profiles wrap the rail also under its base and are drowned inside the reinforced concrete platform assuring the position and the stability of the rail track, moreover an excellent acoustic and electric insulation is guaranteed.
