TPS08 – Rail Fastening System

TPS 08 direct rail fastening system is the original design of Gürmak Demiryolu for ballastless metro projects which having high passenger frequency. The design is capable to compensate lateral and vertical forces of the metro projects. By its high level of absorption capacity, it prevents the vibration and noise of the metro projects to emerge to the surface.

All the components of the system are produced in Gürmak Railway factories with correct and reliable plastic, elastic and metal materials.
