BAS EN 13481-7:2010

This European Standard specifies performance requirements for special fastening systems for switches and crossings and for check rails connected to running rails (not independently fixed to to the bearers) on wood, concrete and steel bearers in ballasted track and on slab track. It applies to switches and crossings as follows: ¾ in main lines having a radius of curvature in divergent track greater than 150 m and subject to a maximum axle load of 260 kN; ¾ in light rail systems having a radius of curvature in divergent track greater than 80 m and subject to a maximum axle load of 130 kN. The requirements apply to fastening systems which incorporate a resilient element and are intended for use with stock rail sections in prEN 13674-1. This European Standard is not applicable to rigid fastening systems. This European Standard is for type approval of a complete fastening assembly only. Requirements for quality control are included in standards applicable to individual components.
