100 MFlex®

ENGINEERED FOR URBAN MOBILITY. BUILT TO LAST ON EVERY JOURNEY.

Recurring loads? Constant stop-and-go? Tight curves? Our 100 MFlex® was designed specifically for these conditions.

ROBUST. FLEXIBLE. EFFICIENT.

In many rail networks, the challenge is not only increasing traffic volume, but also the changing demands placed on infrastructure. Frequent stops and accelerations, tight curves, concentrated loads and limited closure windows require fastening systems that can withstand high mechanical stress while remaining practical to install. In urban transit with narrow corridors and high frequented tracks, operators need solutions that combine durability, flexibility, and reliable performance.  

This is exactly where our 100 MFlex® comes in. Developed for demanding rail applications, the system is designed to handle concentrated loads, resist rail movement and lateral forces, and support fast, efficient installation on site.  

Your challenge meets our solution

Maximum track stability: Significantly increased stability, by virtue of innovative materials and components

Longer service life: > 1,500 Hz natural frequency ensures maximum robustness 

Sustainable track construction: The M7 uses innovative micro-alloyed steel to reduce CO₂ emissions 

Increased safety: Double tilt protection due to middle bend

Welcome to a new era of track construction!

From covered track sections to heavily used rail corridors, fastening systems must combine ease of use with reliable long-term behavior. Our 100 MFlex® is designed to support efficient construction, reduce system complexity, and provide the resilience needed for challenging operating environments. 

Resource-efficient design: Upgradable system solution suitable for covered track applications and high-speed use with a single rail pad.
Easy installation: Optimized component design enables fast, efficient assembly and helps reduce time on site.
High operational safety: Developed to withstand repetitive load cycles, harsh weather exposure, and the demands of intensive rail operation.

Impressive technical data

The technical data demonstrate the performance of the fastening system with examples, although this always depends on external factors and influences. The reference values are based on the requirement standard DIN EN 13481-5; other applications are proven and can be provided based on request.

Precision at every support point

At individual support points, the components of the fastening system take over functions normally provided by concrete sleepers and their shoulders. Our 100 MFlex® DFF provides a highly elastic direct fastening solution for individual support points in slab track. Whether on mainline and urban rail networks, in turnouts or in embedded track, the system offers a high degree of flexibility – making it a flexible and economical solution for a wide range of slab track applications.

Reliable support points for metro and conventional rail

In metro and mainline networks, fastening systems at individual support points take over functions normally provided by continuous concrete sleepers and their shoulders. 

Durable components & reduced vibration: Application-optimized polymer components offer electrical insulation and corrosion protection while cellentic®  reduces vibrations. 

Efficient installation & maintenance: The system’s design simplifies installation and replacement. Fastening components remain in place during rail welding – saving valuable time on site. 

Adaptability for project-specifications: Screw-dowel combination provides secure fixation, while height-adjustment plates allow the system to be adapted to the required track geometry.  

Comfort, quiet operation and durability for urban rail

Tram networks are characterized by frequent acceleration and deceleration, closely spaced stops and operations in sensitive urban environments. Fastening systems must therefore combine high elasticity, reliable rail positioning, and effective vibration control.
Greater ride comfort: cellentic® intermediate layer allows controlled rail deflection and distributes vertical forces effectively, helping to prevent excessive stress.
Reduced vibration & noise: Elastic system design reduces vibrations caused by wheel and track irregularities.
Enhanced electrical insulation: Combination of polymer components, chamber filling elements and protective cover cap effectively insulate against stray currents.
Flexible & economical: Additional components enable use of grooved rails in covered track, supporting smoother wheel-rail interaction and protecting track and train, resulting in longer service life and lower lifecycle costs.
Securely fastened: Our chamber filling elements, base plate and screw-dowel combination hold the rail securely in place and prevent vertical track buckling. 

Flexibility where track geometry changes

Turnouts have particularly high demands on fastening systems. Different rail profiles, changing geometries and varying support conditions must be accommodated reliably across the entire turnout. 

Flexible for a variety of needs: System adapts to the technology, rail profiles and geometries of individual turnout applications.
One consistent fastening concept: Dedicated turnout components enable rails to be fastened securely while maintaining a consistent fastening system throughout the turnout.
Individual adjustment at every support point: Height and lateral adjustment options allow each support point to be aligned precisely with the requirements of the respective turnout section.
