In railways, guard rails or check rails are rails placed parallel to regular running rail to keep the wheels of rolling stock in alignment and to prevent derailment. BS EN 13674-3 discusses railway applications including track and rail infrastructure.
BS EN 13674-3 specifies check rail profiles which have been designed for this purpose. BS EN 13674-3 provides guidelines for the consistency of required product quality on this safety critical component of the track.
Three grades of steel and five rail profiles are specified.
Note: BS EN 13674-3 does not cover guard rails which are to protect vehicle, bridge, viaduct and other structures in the event of a derailment.
BS EN 13674-3 on railway check rail specification is useful for:
In rail transport, check rails perform the vital function of mitigating risks related to derailment. BS EN 13674-3 provides users with dimensions, tolerance measurement, as well as product quality requirements to achieve the product integrity necessary to ensure track safety. Diagrams and tables are provided in BS EN 13674-3 for your reference.
By complying with the standardized design requirements under BS EN 13674-3, you can ensure safety and reliability in the operational efficiency of overall railway infrastructure, while improving service-life of track systems.
