Customer benefits for people living along railways

Soundblock (S-block) is a railway noise barrier placed on the embankment, close to the train. Because the screen is placed close to the sound source, the height does not need to be more than 73 centimeters above the top of rail, to achieve an often acceptable sound reduction of between 5-11 dB (depending on the type of train).

In addition to not affecting the landscape by blocking the view of residents along the railroad, Soundblock is also a cost-effective solution compared to traditional high screens. This is because Soundblocks do not require foundations, as they are stable on the embankment due to their weight of approximately one ton per meter.

When a screen is placed very close to the train, the sound bounces between the screen and the side of the train a number of times. That’s why we use a very innovative and efficient sound absorber made of glass and flint (Vitrumit absorber), which converts sound waves into heat, thereby reducing noise.

We at Z-bloc Norden AB have been developing and manufacturing trackside screens since 1999. Since then, we have delivered many kilometers of trackside screens to 35 different locations, including Botniabanan (5 km) and SL (10 km). Regarding trackside screens in other countries, Norway has for example used 7 kilometers of trackside screens between Sandnes and Stavanger, in Finland there are some smaller stretches and in Germany Deutsche Bahn has prepared for the future by e.g. building a test stretch with Z-bloc (trackside screen) to be able to procure large amounts of screens in the coming years. With Sweden’s 40 or so different sections of near-track screens, we are several years ahead of other European countries. Of course, we at Z-bloc Norden think this is fun and are proud that we have been a major driving force in this development.
