Using mass-spring systems for trackbeds, vibration control is directly provided at the emission source. For this kind of projects the selection and arrangement of the spring elements is usually required in an early phase. By means of static and dynamic analyses, the behaviour of the entire system can be simulated, and hence optimized and adjusted to the prevailing project demands.

General arrangement and reinforcement drawings can be supplied for floating trackbeds. When planning such systems further important aspects have to be considered as the clarification of drainage, design of transition details between different plates, stray current problems. Also a comprehensive consultation during the construction phase can be offered.
