This document specifies requirements for the:

— approval of training facilities, testing and maintaining the skills of aluminothermic welders and welding trainers. It applies to those aluminothermic welding processes compliant with the requirements of EN 14730-1. It requires that the system for training and testing of welders be approved by the railway authority;

— approval of aluminothermic welding contractors. It applies to those contractors using aluminothermic welding processes compliant with the requirements of EN 14730-1 and who employ welders in the possession of a valid permit to weld as defined in Clause 4 of this standard;

— acceptance of the final aluminothermic weld inspections and aluminothermic weld inspectors approved by the railway authority. It does not cover any previous weld inspections by the welder or others.

This document also applies to aluminothermic welds produced on Vignole railway rail 46 kg/m and above, as contained in EN 13674-1.

This document describes a general approach to achieve thermal comfort for passenger compartments or saloons of railway vehicles (single level or double-decker) such as main line, regional/suburban, urban vehicles used in public transportation service.

This document also describes guidelines to specify conditions, performance values and the comfort parameter measurements methods for compartments, saloons and local annexes.

Thermal comfort for a driver’s cab is out of the scope of this document.

This document defines the requirements for buffers with 105 mm, 110 mm and 150 mm stroke for vehicles or units which use buffers and screw coupling. It covers the functionality, interfaces and testing procedures, including pass fail criteria, for buffers.

NOTE 1 Typically, buffers with a stroke of 105 mm are used on freight wagons and locomotives, buffers with a stroke of 110 mm are used on coaches and locomotives and buffers with a stroke of 150 mm are used on freight wagons.

It defines the different categories of buffers, the space envelope, static and dynamic characteristics and energy absorption.

It defines the static and dynamic characteristics of the elastic systems.

It also defines the requirements for buffers with integrated crash elements (crashworthy buffers) for tank wagons for dangerous goods.

The requirements of this document also apply to buffers of locomotives and passenger coaches which are bound to meet the crashworthiness requirements of EN 15227 for normal service only. The properties for the energy absorbing function are defined in EN 15227 and the requirements specified in Clause 7 for tank wagons for dangerous goods are not applicable to the buffers of these locomotives and passenger coaches.

Diagonal buffers are excluded from this document.

For the crashworthy buffers of locomotives, cab cars or passenger coaches according to EN 15227, and tank wagons for dangerous goods or buffers which form part of a combined system consisting of a special buffer and a deformation element, interchangeability with freight wagon buffers is not required, and therefore the requirements of 5.3 (Buffer dimensions) do not apply, those of 5.4 (Mechanical characteristics of buffers) and 5.6 (Marking) apply with restrictions.

NOTE 2 For tank wagons subjected to dangerous goods regulation see [35].

This document specifies the requirements for the draw gear and screw coupling for the end of rolling stock that is bound to couple with other rolling stock (freight wagons, locomotives, passenger vehicles, etc.).

This document covers the functionality, construction, interfaces and testing including pass/fail criteria for draw gear and screw coupling.

The document describes three categories of classification of draw gear and screw coupling, (1 MN, 1,2 MN and 1,5 MN).

Coupling systems between permanently coupled vehicle units are not in the scope of this document.
