Railway applications - Braking - Brake blocks

This document specifies the requirements for the design, dimensions, performance, and testing of a brake block that acts on the wheel tread as part of a tread brake system. NOTE In the scope of Commission Regulation (EU) N° 321/2013 (TSI WAG) the brake block is a friction element for wheel tread brakes. This document does not cover cast iron brake block requirements. This document is applicable to brake blocks of various friction level designed to be fitted to tread braked rail vehicles. This document contains the requirements for interfacing the brake block with the rail vehicle, the testing procedures in order to confirm that it satisfies the basic safety and technical interchangeability requirements, the material control procedures to ensure product quality, reliability and conformity and considers health and environmental needs.

Railway applications - Infrastructure- Noise barriers and related devices acting on airborne sound propagation - Non-acoustic performance - Part 2-1: Mechanical performance under dynamic loadings due to passing trains - Resistance to fatigue

This document describes the basic requirements for the verification of ultimate and serviceability limit states and the resistance to fatigue either of the noise barrier or its components by means of analytical methods and/or tests. Analytical methods can be used for the determination of the characteristic values and design values. Where sufficient information is not available, the analytical procedure can be combined with results from tests. This document provides the following types of test procedures: - test on small samples for defining detail categories, which may not be covered by Eurocodes (verification procedure A); - test on a global element for defining the limit state against fatigue (verification procedure B); - full scale tests under a given representative loading (verification procedure C) to determine fatigue resistance of the noise barrier components for defined loading conditions; verification procedure C is given as alternative to verification procedures A and B.

Railway applications - Closing and locking devices for payload protecting devices of freight wagons

This document specifies the requirements for closing and locking devices of heavy rail freight wagons including durability, their status indication, maintenance and recycling. Annex A specifies pass-fail criteria for the dimensioning tests. This document is not applicable to closing and locking devices which are used to ensure a pressure difference or to retain liquids/liquid payloads. This document is not applicable to heavy rail freight wagons which are emptied by pressure, nor is it applicable to lose tarpaulins.
