BS EN 13146 is a European standard that discusses railway applications and track test methods. The aim of the BS EN 13146 series is to increase operational efficiency and performance of track systems.
BS EN 13146‑1 is the first part of a multi-series of documents that specifies the laboratory test procedure to determine:
BS EN 13146‑1 on longitudinal rail restraint for fastening systems is relevant to:
The main function of rail fastening systems is to fix rails to railway sleeper or railroad ties. Fastening systems generally consist of rail anchors, rail tie plates, chairs, fasteners, spikes, screws, bolts, etc.
For fastening systems that hold the rail mechanically (whether at discrete intervals or continuously) the test procedure in BS EN 13146‑1 measures the longitudinal rail restraint. For an embedded rail with an adhesive fastening system the test procedure measures the longitudinal stiffness.
As a result, you can determine the extent of resistance to braking and traction forces, thus ensuring that rail support system rigidity, track geometry and constant gauge length is maintained. Ultimately this can minimize the risk of derailment.
Overall, adopting BS EN 13146‑1-compliant tests for fastening systems ensures operational safety of the railway and vehicle with enhanced track stability. With high-performance fastening systems, the ability to absorb rail shock can also improve comfort levels for passengers.
BS EN 13146‑1:2019 supersedes BS EN 13146‑1:2012+A1:2014, which is withdrawn. BS EN 13146‑1:2019 has been editorially revised. Compared with EN 13146‑1:2012+A1:2014, the following changes have been made:
