KE1/2 and KE1/4 rail fastening systems

KE1/4 and KE1/2 systems are designed for ballastless tracks.


KE1/4 system is designed for C and D category railway lines, while KE1/2 system is designed for D category railway lines according to EN 13481-5: 2017 standard. KE1/4 and KE1/2 systems meet all the EN 13481-5: 2017 standard requirements. The system ensures low static stiffness.

Characteristics and Advantages of the KE1/2 and KE1/4 Systems:

  • Both systems enable horizontal position adjustments within ┬▒5 mm (with 1 mm step) from the nominal position using the eccentrics
  • Both systems provide excellent electrical insulation by using a regulation collar and insulation bushing made of plastic
  • Regulation of vertical position through with regulation pads
  • The use of nuts with non-standard size polyamide inserts makes it difficulty to dismantle the system by unauthorized persons
  • Static stiffness of the system in standard version: up to 25 kN/mm (it is possible to adjust static stiffness according to the customer needs)
