Strailastic Australia represents Kraiburg Strails world-wide noise attenuation subsidiary Strailastic which includes key product areas reducing noise and improving safety around the railway developed in the last 25 years. It includes Light rail encapsulation systems, mini noise walls, rail web dampers, sub ballast mat and platform gap fillers. Noise is most effectively reduced along the propagation path at the source. This is why modern sound protection systems are designed to get as close to the rail / wheel interface and clearance area as possible.
The sound protection products by STRAILastic comply with all prescribed minimum kinematic envelope dimensions and distances to maximize the noise reduction achieved to fight railway noise at its source whilst ensuring no operational impediments occur.
Light Rail Track systems – the company offers extensive experience with over 330 kms of its TOR plus GRS track encapsulation installed and another 130 kms of green tracks across more than 60 cities in Europe.
Mini sound walls . This innovative new line of low-profile noise walls can absorb upto 11dBA. In Germany, the tolerance threshold for railway noise and interference, e.g. in the landscape and the railway embankment biotope is comparatively low requiring cost effective noise treatments. Previously to counter high noise levels, metres-high, opaque sound typically concrete barriers that flank the railway lines are often erected then graffitied. These create a large visual blight on the landscape and restrict views from the trains. However, the new sound protection systems from STRAILastic provide an alternative solution which, when used in combination or singularly, can reduce noise levels significantly without impacting the landscape and obstructing views.
The products are made from a special combination of high-quality UV and ozone-resistant rubber, with stable fibre reinforcement to counter the pressure and suction forces from rail traffic. This allows these products to be installed at the shortest possible distance from the source of noise generation – the contact surface of wheel and rail.
The solutions can include combining various noise and vibration sound protection products from STRAILastic to significantly reduce the rail wheel noise emitted from the rail corridor:
● Rail Web Dampers : STRAILastic_Synth and the A inox 2.0 is the latest version of the STRAILastic_A rail web dampers, internationally proven for years
● mSW Noise Walls: Two versions of the Mini sound walls are available with Version 1 a fullv vulcanised rubber with 70% recycled materials panels in different configurations and the new Version 2 with its high absorbing face able to reduce noise by upto 11 dBA. The original full rubber STRAILastic_lP vertical panel creates peace and quiet (upto 5 dBA) by using the existing structures to bolt to. The infill panels can be mounted directly onto standard bridge railings or concrete walls and the reverse side of the panels can even be customised to perfectly blend into their surroundings. STRAILastic_mSW Version 2 with its mini sound protection wall from 390mm high to 12000mm high either directly fixed to the sleeper ends, standing on screw pile foundations or concrete bearers which gets closer to the source of noise than any other existing sound barrier.
Sub Ballast Mat SBM 10 from Kraiburg. This high quality product sourced from its mass spring building vibration isolation products provides both protection an vibarion dampening to structures under the rail line.
Platform Gap fillers: Platform Gap Fillers provide a key safety improvement to stop passengers slipping between the train and the station platform closes the gap to the side fo the train. These are fully frangible.
These combinations of solutions will more than meet all of the client’s noise control requirements, while also perfectly blending into the landscape with aluminum patterned panels attached on the obverse side. Importantly a key decisive selection criterion for STRAILastic products is that no planning approval procedure is required for their installation on the track. All products have been approved by the Federal Railway Authority (EBA) in Europe and they can be individually adapted during the design planning phase, and within certain limits also during installation, as required.
