Rail traffic causes airborne noise as well as vibrations or structure-borne sound. Residential and commercial locations are normally the sufferers of these emissions.
Calenberg Ingenieure use elastomeric products for their rail track program. They are produced from high grade natural and synthetic rubbers. Due to the different variants within the product range, individual solutions for nearly every vibration and noise problem can be offered.
The new ‘Wendlingen – Ulm’ line in Baden-Württemberg, Germany, will create an infrastructure designed for 250km/h. Slab track will be used for the superstructure.
To cope with the particular challenges of trains riding over bridges and crossings at high speeds, various technical solutions must be brought into use to protect the structures.
Among other things, Calenberg directional control bearings are used on the bridges. The directional control bearing consists of a stainless-steel support with anchorages onto which a high-quality rubber compound is vulcanized. These are then fitted in a vertical position to the side bench of the bridge and – in combination with other measures – absorb horizontal forces and help stabilize the slab track position.
A new track system and tunnel structure at DB's Augsburg Central Station will be supported with Calenberg USM 1000 W.
At iaf 2022, Calenberg Ingenieure will present elastic mass-spring systems, EPDM intermediate layers and plates, and under ballast mats.
Calenberg Ingenieure's USM series provides solutions for isolating the permanent way, reducing both vibration and sound in its surroundings.
