Mass-spring systems from Getzner provide particularly effective protection against vibrations and noise for people living next to railway lines. The systems are used wherever protection against disruptive vibrations is the priority.
Getzner offers three variants for supporting mass-spring systems: full-surface, strip and point bearings. Which of these types to use depends on economic as well as technical considerations. The success that is achieved can be felt and heard. The lowest natural frequency achieved in the numerous mass-spring systems realised to date in local and long-distance railway lines is 5 Hz.
Mass-spring systems using bearings by Getzner have so far been installed in over forty cities, on high-speed lines and on various standard gauge lines worldwide.
