Bridges come in all shapes and sizes and therefore require a flexible rail fastening system to accommodate the various requirements for fixation, whether that be on timber/FFU bearers or direct to steel or concrete structure.
We also provide solutions for track structure interaction in the form of low toe load or zero toe load fastening systems which are designed deal with potentially high forces being transferred from the rail to the structure. Pandrol have a capability to model the longitudinal forces and provide support and recommendations accordingly.
Some of the Pandrol products can provide zero longitudinal restraint (ZLR) capability which can allow the rail to move longitudinally without transferring any load to the structure. This can provide the opportunity to separate the rail expansion joints and structural expansion joints to different locations for improved safety.
Ballasted track on bridges can generally be considered as plain line track although for very long structures some consideration for track structure interaction may be required.
The nature of bridges can often lead to secondary noise from elements of the bridge structure which may resonate as a result of vibration from the passing train. To deal with this Pandrol provides several options from high to very low attenuation systems.

The Pandrol Safe Driven (SD) fastening system is a pre-assembled, economical yet high performance screwed fastening solution for all categories of track. SD means ‘Safely Driven’, referring to the controlled clip guidance from the parked to the in-service position. In addition to its ability of pre-assembly in the concrete sleeper, SD systems have also been designed in order to […]
The PANDROL FASTCLIP FE system is a resilient, threadless, pre-assembled rail fastening system with low installed cost. Pandrol FASTCLIP has substantial global references and has been designed as a total system in which all components are delivered to site pre-assembled on the sleeper. Once the sleepers are laid, and the rail installed, the clip is […]
PANDROL 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 the most sensitive areas to these environmental concerns. Pandrol Vanguard assemblies are suitable for application on concrete sleepers and […]
PANDROL VIPA SP is a high performance 2 pad, 2 plate system providing a wide range of applications for concrete, timber and slab track forms. Pandrol VIPA SP is a resilient track support system that has been developed to attenuate the wheel/rail contact induced vibrations that are transferred from the rail to the supporting structure. The concept is […]
The Bonded DFF ADH system has been developed for plain line and turn out applications to directly combat corrugation and vibration problems caused by major dynamic forces generated from passing trains. Drawing on some 30 years’ experience, the DFF ADH system is suitable for slab tracks of all types and concrete sleepers. The Bonded DFF ADH fastening system […]
