Fastening Systems


Vanguard is a unique rail fastening system with very low vertical dynamic stiffness that leads to high levels of vibration isolation.

The significant reduction of vibration and secondary noise makes it ideal for applications in areas that are most sensitive to these environmental concerns. Pandrol Vanguard assemblies are suitable for application on slab track, concrete sleepers and timber sleepers, and can be used on bridges, viaducts and in tunnels. It delivers exceptional vibration attenuation at a much lower cost than floating slab track and does not compromise on rail roll.


Technical Features

  • The system can be installed on new track construction and is also suitable for retrofitting existing rail fastening systems where reduction in ground borne noise or secondary vibration is required
  • Designed with rubber wedges which support the web of the rail and prevent excessive rail roll to provide a very low stiffness down to 4 kN/mm
  • Low profile system, that can be easily retrofitted (with various footprint designs)
  • High level of lateral and vertical adjustability
  • Natural frequency of approximately 20-25 Hz


  • The nature of the rubber wedge support and the robust design of the assembly provides an ultra low maintenance system with a very long life expectancy in track
  • The very low profile of the Vanguard fastening system means it can be installed within existing restricted rail heights and can therefore be used to increase the vibration isolation properties of an existing track form
  • Pandrol Vanguard is suitable for use on bridges to attenuate vibration which can otherwise lead to secondary noise from other parts of the bridge structure which may resonate. As Vanguard is an indirect baseplated system it can be applied directly to bridge girders or to the surface of timber, concrete or FFU bridge bearers and also on timber or concrete sleepers on ballasted bridge decks
