Rail Fastenings Systems

SD System

The Pandrol Safe Driven (SD) fastening system is a pre-assembled, economical yet high performance screwed fastening solution for all categories of track.

The fastening system is designed with controlled clip guidance from the parked to the in-service position. The SD System is developed for pre-assembly in the concrete tie, and can additionally deliver high rates of installation by mechanical methods.

Technical Features

Advantages

  • All SD components leave the tie factory fully pre-assembled on the tie, delivering savings in manpower, as well as reduced distribution and handling costs during track laying, stressing and rail changing
  • An easy-to-install design reduces the installed cost of the rail fastenings and can provide further savings during the life of the fastening each time the clips are removed and installed for rail maintenance activities
  • All components remain captive during the rail stressing procedure to allow a simplified stressing procedure. The clip is simply withdrawn back to the parked position to release the rail
