This document specifies restoration by electric arc welding and is limited to the head of the rails only. This document describes the approval systems for consumables and procedures used in manual metal arc and flux cored metal deposit rail repair welding. This document includes the quality-related tasks and responsibilities of personnel involved in the electric arc repair welding of rails. This document applies to plain rail and switches and crossings manufactured from new Vignole railway rails R200, R220, R260, R260Mn, and R350HT grades rails of 27 kg/m and above as contained in EN 13674-1, EN 13674-2 and EN 13674-4. The permitted welding processes are limited to Electric Arc (EA) in accordance with EN ISO 4063 and are by description Process No 111: SMAW (Shielded Metal Arc Welding) and Process No 114: FCAW (Flux Cored Arc Welding). This document can be applied in situ, at line side or at out of track locations. The flash welded leg ends of austenitic manganese steel crossings are included in this document, except when located within 500 mm of manganese crossings. Where repairs are required within 500 mm, refer to EN 16725.

This European Standard specifies the requirements for the digital automatic coupler (DAC) for freight compliant with the Technical Specification relating to the subsystem ‘rolling stock — freight wagons’ of the rail system in the European Union Commission Regulation (EU) No 321/2013 of 13 March 2013 and repealing Decision 2006/861/EC and EU regulation 2019/776. Commission Regulation (EU) No 1302/2014 of 18 November 2014 concerning a technical specification for interoperability relating to the ‘rolling stock — locomotives and passenger rolling stock’. This standard specifies the minimum interface requirements to allow automatic coupling (mechanical and pneumatic) of two digital automatic couplers. The standard further specifies the mechanical interfaces needed for the interoperability of electrical couplers. It does not cover the electrical contacts needed. The standard covers the requirements for DACs integrated into locomotives. Coupler-to-coupler interfaces for the Hybrid coupler solutions will be covered in this standard. All non-mechanical interfaces such as the digital and electrical requirements needed for the DAC are defined in the scope of CENELEC/TC9X/WG 15-10.

This document defines: - general design rules for access to the metro cab, - front visibility conditions including positions of people, - assessment. This document applies to metro vehicles with or without driver, excluding shuttles used for short distance transportation. Metro vehicle definition is according to EN 17343.
