Railway track systems Variant Vossloh System W-Tram - with Wedge angle plates Page: 119-09 Rail fastening system W-Tram with wedge angular guide lates K-Wfp 14 R and L With the wedge angular guide plates with a continuous adjustment, the limited rail foot tolerance related to manufacturing process, above all balanced in grooved rails, and so the track width can be regulated upto +/-10 mm. In the slab track, the use of insulated anchor bolts is possible, alternatively the proven anchor screw combination Sdü 26/Ss 36. The lateral forces of the rail is carried on the angular guide plate and the base plate in the concrete support plate. Does not have the bending or shear forces on the embedded anchorage system. High power dissipation by the profiled bottom of the base plate. The sleeper screw / anchor bolts is only subjected to train. Completely electrically insulated. For laying the rail grooves on concrete sleepers, the system W is used, for slab track the system WTram is used.
