Protrack - Classic

protrack classicRail side profiles

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.

Protrack ClassicThe Protrack line profiles are available for any type of rail and are supplied in 0.75 to 1.5 meter length bars.

With the "Protrack Classic" line we obtain an excellent mechanical junction between the rail and railbed, in order to guarantee a durable junction between rail and connecting pavement.

These profiles cover the lateral side of the rail face and can be used on tracks with connecting pavements and /or green tracks. It is possible to obtain electrical insulation by using specific pads, placed under the rail base.
