Why should you use BS EN 13481-1 - definitions of fastening systems for tracks?  
The rail fastening system is responsible for fixing the rail on the track slab. Fastening systems generally consist of rail anchors, rail tie plates, chairs, fasteners, spikes, screws, bolts, etc.
BS EN 13481-1 helps you to assess the suitability of fastening systems for use on railway tracks.
BS EN 13481-1 specifies fastening system categories based on the speed and axle load of trains on the tracks for which they are built, as well as the rail section utilized.
BS EN 13481-1 guidelines contribute towards ensuring operational safety of rail track stability. With high-performance fastening systems, the ability to absorb rail shock can improve comfort levels for passengers. BS EN 13481-1 functions as your reference guide for the rest of the standards of the series so that passengers and commuters safely reach their destinations.
