What is BS EN 17319 about?
BS EN 17319 is applicable to fastening systems used with grooved rails for the tram, urban rail and industrial tracks, with maximum design axle loads and minimum curve radii.
Note: BS EN 17319 is not applicable to fastening systems for other rail sections or special fastening systems used at bolted joints or glued joints or in switches and crossings for grooved rails.
Note: Requirements for fastenings for use with Vignole rails are included in the EN 13481 series of standards.
Who is BS EN 17319 for?
BS EN 17319 on performance requirements of rail fastening systems is relevant to:
- Manufacturers of rail fastening systems
- Trian operating companies (TOC)s
- Supplier of the fastening system
- Railway management authorities
- Infrastructure manager
Why should you use BS EN 17319?
Fastening systems are an assembly of components which secures a rail to the supporting structure and retains it in the required position whilst permitting any necessary vertical, lateral and longitudinal movement. Such an assembly includes components to distribute the loads from the rail into the supporting structure, and where necessary to prevent wear of the contact surfaces on the supporting structure and to electrically insulate the rail from the supporting structure.
BS EN 17319 ensure that the fastening system provides the necessary degree of electrical insulation between the rail and the supporting structure, which may be crucial in terms of track circuit signalling function as well as protection against the effects of stray currents.
BS EN 17319 can assist you in avoiding a fatigue fracture at the fillet radius between the web and the rail's foot. Overall, BS EN 17319 can assist you in maintaining the fatigue strength of the rail itself.
