Rail Fastenings Systems

Vanguard Common Interface

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.

Vanguard Common Interface product overview

As its name suggests, the assembly fits on a common interface and is fully interchangeable with a range of fastenings, including FCA and DFC.

  • When noise and vibration mitigation requirements change, rather than having to modify or replace the whole track, the fastening system can simply be swapped
  • Vanguard offers all the advantages of a regular Vanguard fixing, including very low vertical stiffness and high levels of vibration isolation and adjustability
  • A wide range of vertical and lateral adjustments can be achieved with minimal tools and components, allowing for efficient heave and gauge adjustment and correction for track settlement

Benefits of the Vanguard Common Interface

01

Increased flexibility

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.

02

Easy installation

The Vanguard has been designed for ease of installation and maintenance with minimal special tools, saving time and reducing equipment needed.

03

Low stiffness

With a very low stiffness assembly (5kN/mm), the Vanguard results in high levels of vibration mitigation.

04

Electrical insulation and corrosion protection

The system provides full electrical insulation and corrosion protection.

05

Simple

Pandrol’s common interface system simplifies tooling and training for concrete plants.

06

Low maintenance

The use of recyclable materials avoids waste, helps to reduce CO2 emissions, and contributes to the overall sustainability of the railway.

Technical features of the Vanguard Common Interface

01

Common interface

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.

02

Vertical and lateral adjustment

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.

03

Indirect rail holding

The Vanguard indirect rail holding mechanism is separate from the concrete substrate.

04

Efficient maintenance

The system has been designed to ‘fit and forget’, with very little maintenance required. Minimal special tools are needed for installation and maintenance.

05

Highly evolved

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.

06

Recyclability

The Vanguard is composed of recyclable materials.
