Fit & Forget track solution
edilon)(sedra DFS (Direct Fastening System) is a rail fastening system for ballastless tracks, in which the rail is directly fastened by means of a rail clip to a baseplate. The system components can be tailored to different track geometries and offer a high degree of convenience and flexibility in installation.
Based on the mechanical properties of universal components.
Extensive information about portals and procedures: BOTTOM-UP or TOP-DOWN.
The system is suitable for all types of installations, and especially in those situations
that require a more complicated installation, such as those on embankments or on
bridges. Regulation, if necessary, is carried out using toothed devices and/or shims.
We install insulators, resilient pad, natural rubber in bonded base-plate, polymer plate.
We can adjust the resilient material for vibration mitigation.
Easily adjustable baseplates
The baseplates are easily adjustable both in height and laterally. Various track rigidities can be set. The intended use is for all types of rail traffic such as tram, metro, freight & commuter trains. The baseplates are compatible with all rail types, such as the standard vignole and grooved rail. Due to its high insulating properties, DFS offers a high degree of stray current control and stands up to extremely variable climatic influences.
