Rail Fastenings Systems

VIPA DFC

The Pandrol VIPA DFC System has been optimised for use in pre-cast blocks, sleepers and slabs. It is an economical, high performance solution for track where some noise and vibration mitigation is required.

The system has been designed with pre-cast applications in mind. This has allowed the engineers to design the system economically using long-proven embedded cast shoulder technology to transfer the lateral loading into the pre-cast element.

 

Technical Features

  • Designed for use on slab tracks where a typical vertical static stiffness of 20-25 kN/mm is required for applications on light rail, metro, high speed and other non-ballasted tracks
  • The Pandrol VIPA range of products uses 2 layers of resilience to provide attenuation of vibrations, 1 layer of resilience under the baseplate and a second layer under the rail
  • VIPA DFC exhibits a high level of electrical insulation through 2 levels of insulation, the rail being insulated from the baseplate and the baseplate being insulated from the concrete slab or sleeper
  • Track / structure interaction can be accommodated by low toe load / rail free variants

Advantages

  • The VIPA DFC has been designed with pre-cast applications in mind. This has allowed the engineers to design the system economically using long-proven embedded cast shoulder technology to transfer the lateral loading into the pre-cast element
  • The system is an adjustable indirect baseplate type, ideally suited for installation on pre-cast blocks, sleepers or slabs, but can also be installed using the wet-pour top-down methods
  • The Pandrol Fastclip fastening allows for efficient stressing and rail maintenance through optimisation of mechanisation, and switch-on, switch-off features
