This document specifies the requirements on rail aluminothermic welding, including the requirements for approval process, laboratory tests, approval of welder and contractor, as well as the acceptance criteria of aluminothermic welds in track. This document concerns the welding of 43 kg/m to 75 kg/m new vignole rails of the same profiles and the same grades. This document is restricted to butt welding for connecting rail ends. NOTE Conformity with the requirements of this document does not ensure the suitability of a welding process for specific conditions of track and traffic. This document does not cover welds made between different rail sections, differently worn rails or different rail grades.

This document specifies the minimum requirements to meet by measuring systems fitted on track geometry measuring trolleys and manually operated devices to give an evaluation of track geometry quality when using one or more of the parameters described in EN 13848 1. It sets out the acceptable differences from EN 13848 1 when using track geometry measuring trolleys and manually operated devices to measure track geometry.
It applies to all track geometry measuring systems fitted to track geometry measuring trolleys and manually operated devices after the date of implementation of this document.
In the case of lightweight devices working at a speed higher than walking speed, or in the case of track geometry measuring systems installed on track recording cars but not measuring in loaded conditions as defined in EN 13848 1, the test procedure defined in EN 13848 2 is applicable.

This document specifies methods for measuring and analysing irregularities of running surfaces for use in the prediction and assessment of ground-borne noise and vibration arising from railway systems. This document a) defines the data that can be described as rail or wheel roughness and that can be used to quantify a source term for the generation of the dynamic forces that can lead to ground-borne vibration from railway vehicles, b) gives guidance regarding the types of equipment that can be used to measure roughness as a variation of height along the running direction of the rail surface or wheel parameter, c) gives guidance regarding the methods that can be used to obtain an estimate of the roughness wavelength spectrum from measurement records taken over a length of rail head or wheel perimeter, and d) gives guidance regarding the presentation of a roughness spectrum representing the condition of a length of rail or of a wheel related to its ability to generate vibration. This document does not e) give guidance regarding the characterization of localized geometrical features (e.g. switches, crossings, rail squats, occasional rail joints and localized geometrical defects of the running surface). These features are likely to produce dynamic forces that are not linear with their amplitude because of the change of geometry at the wheel-rail contact. Hence these features are not characterized by methods of analysis defined within this document. Annex A provides further information regarding the characterization of localized geometrical features, f) give guidance regarding the specification or testing of roughness measurement equipment that can be used. Annex B provides an overview of measuring equipment, g) give guidance regarding the measurement or analysis of track quality for any other purpose than the assessment of ground-borne vibration, h) present any example of roughness spectra intended to represent typical roughness. Roughness levels vary greatly between track sites and any examples used in this document have not been selected on any other basis than their usefulness for the purpose of demonstrating the principles of analysis, i) promote any particular make, model or manufacturer of measurement equipment, and j) recommend or promote software for the implementation of the analysis procedure.

This European Standard deals with mechanical rail joints for flat bottom rails 46 kg/m and over. The scope of this standard is: to
establish requirements for insulated and non-insulated rail joints, for stressed rail (continuous welded rail, CWR) and unstressed rail (jointed track); to define mechanical and electrical requirements for type approval and for acceptance of insulated rail joints which are manufactured in a factory (prefab construction) as well as assembled onsite (site construction). This standard specifies the minimum requirements. Special applications as for instance tram systems may require different demands in certain paragraphs and should be agreed between customer and supplier. The scope also excludes expansion joints (it is covered in EN 13232-8), and special joints in switch constructions.
