Vanguard is the ideal fastening system when the transmission of vibration and noise from track to nearby buildings needs to be reduced. It achieves this by providing exceptionally low vertical stiffness and therefore high levels of vibration isolation between the rail and the slab or tie. At the same time, it does not compromise the control of lateral rail head movement and dynamic track gauge.
As it provides effective vibration isolation when used on plain slab track, Vanguard can be retrofitted to many existing tracks where noise and vibration need to be addressed. In addition, it can provide significant cost savings when used in new tunnel projects, as it can be fitted in tunnels of smaller diameter than alternative systems.
