BS EN 13481-7:2022

Railway applications — Track — Performance requirements for fastening systems. Fastening systems for switches and crossings, check rails, insulated rail joints and rail expansion devices | Status: Current

1 Scope This document is applicable to fastening systems in Categories A – E as specified in EN 13481‑1:2012, 3.1 for use in switches and crossings (S&C). It also provides guidance on evaluating fastening systems for check rails, expansion devices and insulated rail joints whether in switches and crossings or in plain line. The document applies to five categories of fastenings used in tracks with respective maximum axle loads and minimum curve radii as shown in Table 1. Table 1 — Fastening category criteria Category Maximum design axle load kN Minimum curve radius (plain line) m A 130 40 B 180 80 C 260 150 D 260 400 E 350 150

NOTE 1 The maximum axle load for Categories A and B does not apply to maintenance vehicles.

NOTE 2 The minimum curve radius is not applicable to applications in switches and crossings.

The requirements apply to fastening systems for rail sections included in the EN 13674 series of standards (excluding 49E4). This document is not applicable to fastening systems for other rail sections or rigid fastening systems used on running rails. This document is for type approval of complete fastening systems.
