The Vanguard Common Interface (CI) fastening system adds an unequalled level of futureproofing to slab panel constructions. Vanguard (CI) is part of our Common Interface range.
Pandrol’s Common Interface System provides a common connection point for a range of different direct and indirect fastening assemblies. A common base accommodates three different fastenings: FCA, DFC and Vanguard. As a result, when noise and vibration mitigation requirements change, rather than having to modify or replace the whole track, the fastening system can simply be swapped out.
As its name suggests, the assembly fits on a common interface and is fully interchangeable with a range of fastenings, including FCA and DFC.
The high degree of flexibility offered by being able to change the fastenings on the common interface allows for greater futureproofing of non-ballasted track than in the past. Where noise and vibration concerns demand changes to stiffness, instead of having to modify or rebuild the whole track, the fastening system alone can be changed. This saves time, results in minimal disruption to track access and reduces cost.
The Vanguard has been designed for ease of installation and maintenance with minimal special tools, saving time and reducing equipment needed.
With a very low stiffness assembly (5kN/mm), the Vanguard results in high levels of vibration mitigation.
The system provides full electrical insulation and corrosion protection.
Pandrol’s common interface system simplifies tooling and training for concrete plants.
The use of recyclable materials avoids waste, helps to reduce CO2 emissions, and contributes to the overall sustainability of the railway.
The Vanguard assembly is interchangeable on Pandrol’s common interface with FCA and DFC fastening systems, to allow for different levels of stiffness (resilience) without changing the substrate.
With the addition of a raiser, vertical height corrections of up to 53mm can be made in 1mm intervals. Total track gauge adjustment of 16mm (8mm per rail seat) can be made.
The Vanguard indirect rail holding mechanism is separate from the concrete substrate.
The system has been designed to ‘fit and forget’, with very little maintenance required. Minimal special tools are needed for installation and maintenance.
Fastclip FCA is an adjustable evolution of the globally trusted Pandrol Fastclip product. Component materials are based on long established Pandrol specifications. Low clamping force, joint-bar and rail-free variants are available to meet special track needs.
The Vanguard is composed of recyclable materials.
