The fastening system W-Tram has been developed as a single support point with screw-dowel combination for urban transport, especially for tram projects. Thanks to the high proportion of long- lasting plastics, the system W-Tram ensures corrosion protection and electrical insulation. In more than 40 years, the system W-Tram has proven to be successful on rail tracks of a length of approx. 600 km all over the world.

Easy handling for installation and rail maintenance

*Flexibly applicable as single support point: no special shoulders (e.g. for concrete sleepers) required.

*Installation is possible both with bottom up (by bottom casting of base plate) and top-down method.

*For welding of the rail, no fastening elements have to be removed from the support point.

*All components can be replaced.

How to install W-Tram fastening system?

Application in covered track possible Caps for Skl, angled guide plates and screw, as well as chamber filling elements, fastened to the web of rail, allow the use of the system with grooved rails in the covered track.

Angled guide plates keep the rail in the track The angled guide plates lead the forces introduced into the rail by train in the base plate first and then into the concrete. In this way, the screw-dowel-combinations are not loaded by shearing and bending forces. The design additionally supports the tilting protection. Different widths can adjust the gauge.

Adjustable height Using height adjustment plates, the height of the system can be regulated within 20 mm. With the optimized height adjustment plates NG the cellentic rail pad rests completely on the bearing face.

The W-shape of the Skl 21 provides safety For meeting the required rail creep resistance two highly elastic, independently acting spring arms steadily hold the rail down; the middle bend acts as an additional 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.

cellentic rail pad for high elasticity The elasticity of the cellentic pad compensates the impacts of the vertical forces and with this, stable rail deflection; it also damps vibrations and minimizes the structure-borne noise.

Securely clamped with the screw-dowel combination NG The high-quality dowels made of hightech material are extremely strong and efficient: Lateral forces are reduced, this leads to a decrease in the load on the slab track.
