Long History Of Rolling Stock Acoustic Safety 

Taking its heritage from the renowned Kockum Shipyard, Kockum Sonics as a part of the Kockumation Group has been active in the field of rolling stock for more than 90 years. In 1922, the Swedish Railway Company purchased three railcars from Deutsche Werke Kiel for operation in the south of Sweden. These were the first rail vehicles to have a Tyfon^® installed, and the rest is history. Since then the company has grown into a worldwide leading supplier of warning horns for the railway industry.
