These fastening systems 300, are suitable for use on the slab track (ballastless) sections of an intercity railway project with an axle load of 25 tonnes and a design speed of 160 km/h.
Fastening System 300
Elastic. Safe. Resilient. Flexible.


The W-shape of the skl 15 clip provides safety
For meeting the required rail creep resistance two highly elastic, independently acting spring arms stead-ily hold the rail down, the middle bend acts as an addi-tional tilting protection. With its high fatigue strength,it resists the dynamic vertical movements that are caused when the vehicle rolls over the rail. The system is maintenance-free: Due to the permanently acting tension, Skl and screw cannot loosen, the middle bend prevents the spring arms from plastic deformation.

Angle guide plates keep the railin the track
The angle guide plates lead the forces introduced into the rail by train in the concrete. In this way, the screw-dowel combinations are loaded by shearin gand bending forces. The design of the angle guide plates additionally supportsthe tilting protection. Different widths can regulate the gauge.

A steel plate ensures an optimum distribution of load
A steel plate ensures load distribution from the rail foot to the elastic inter-mediate plate and offers additional tilting protection through its large sur-face. A plastic rail pad insulates therail electrically.
Highly-elastic intermediate plate for less vibration
The elasticity of the special cellentic material ensures stable rail deflection;Vibrations and structure-bome noiseare minimised.
Easy handling for installation and rail maintenance dueto preassembly and exchangeability
- All parts of the fastening system can be preassembled in the factory for sleepers and prefabricated elements.
- At the construction site, it will only be required to lay the rail and clamp it. That way, fastening components cannot get lost.
- For welding of the rail, no fastening elements have to be removed from the support point.
- All components, including dowels, can be replaced.
