NEUSSER STRASSE RAIL TRIANGLE

THE PROJECT AND ITS REQUIREMENT

The KVB is building a new depot for light rail vehicles in Cologne Weidenpesch. The feeder will be integrated into the lines 12 and 15 by means of a switch system. Passing trams may cause vibrations which are then transmitted into the ground and affect the surrounding buildings.
To protect the residents from these vibrations, a massspring system was installed.

THE SOLUTION

The turnout system is supported by a continuous massspring system. For elastic decoupling, approx. 600 m² of Calenberg USM 2020 are used as floor and side mats.
The floor mat is laid loosely on the concrete base. The side mat is fixed by means of a Z-profile. A rigid connection between the permanent way and the subfloor is interrupted by the mat. The USM 2020 reduces the dynamic forces acting on the surroundings in such a way that the residents are effectively protected from vibrations.
 

The advantages:

• Delivery of cut-to-length mats enables efficient installation
• No water absorption of the mat
• All over drainage underneath the mat due to profiling
• Concreting of the track support plate directly on the mat
