eco-clip

 - Increase the longitudinal friction factor increase the displacement range

 - Change the shape of the toe to get the areal contact with insulator and increase the whole length

   to increase  displacement range to accommodate the elastic pad  deflection

 Insulator

  - Stress decreased by areal contact with eco-clip

  - Extended life cycle

 Rail Pad: high elastic pad made of EPDM

  - Static stiffness: 60kN/mm+/-10%

  - Stiffness variation after repeated load test by EN Standard:  +/-5%

  - Guarantees the long life cycle

 Shoulder

  - Increase torsional resistamce

 PC Sleeper

  - Designed more bigger and wider

  - Decrease the trackbed stress

  - Secure the safe vehicle travelling at high  speed
