ISO/TS 14837-31:2017 gives guidelines to encourage reporting of field measurements of ground-borne noise and vibration in a metric that allows international comparison and future development of empirical models. It also sets out the basic minimum requirements and good practice when taking measurements for the evaluation of human exposure in residential buildings to ensure they are reliable. While national standards or requirements based upon project-specific purposes would normally take priority, this guidance can be used where there are no particular requirements or to provide supplementary guidance. Thereby, this document provides a means of improving general quality and reporting of field measurements in a preferred format. There are a number of reasons for carrying out field measurements of ground-borne noise and vibration arising from rail operations, from complaint investigations to validation of prediction models, diagnostics and research as detailed in ISO 14837‑1:2005, 7.2. In the present document, two levels of evaluation are considered. - Scope 1 corresponds to basic measurements of floor vibration and noise in rooms in buildings to evaluate the human exposure to ground-borne vibration and ground-borne noise. Requirements are presented under two levels of accuracy: basic measurements with minimum accuracy; measurements with reduced uncertainty, also more reproducible and more appropriate for prediction. Ground-borne noise is noise generated by vibrating building elements (e.g. floors, walls and ceilings) in the room of interest and is therefore best expressed by both an acoustic and a vibrational quantity. Its identification as ground-borne noise (as opposed to airborne noise, potentially also present) requires simultaneous noise and vibration measurements. Nevertheless, there are also cases of very low frequency vibration (below 10 Hz to 16 Hz) where only vibration measurements are relevant. Rattle can also arise from vibration, which can be from building components or furniture. This document does not set out to characterize this phenomenon, but to note its presence when it occurs. NOTE In some cases, Scope 1 can relate to measurements on the ground outside a building (to resolve access issues or to comply with national regulations), although measurements at the building are generally preferred. - Scope 2 corresponds to measurements extended to evaluate the vibration immission to buildings, which includes vibration measurements at or near the building foundations and vibration measurements on ground next to the building so that the building coupling loss and building transmissibility can be estimated. Vibration measurements near the tracks (on ground surface or in tunnels) for a proper characterization of the source are outside the scope of this document. Certain requirements are specified in the interest of achieving a consistent minimum data set for each investigation, allowing data comparison between sites.

This European Standard is also applicable where track alignment takes into account vehicles that have been approved for high cant deficiencies (including tilting trains).
More restrictive requirements of the Technical Specifications for Interoperability (TSI) and other (national, company, etc.) rules will apply.

This part of EN 13230 defines technical criteria and control procedures which have to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, bearers for switches and crossings, and special elements for railway tracks.
The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use they are also exposed to frost damage and to moisture, which can result in detrimental chemical reactions within the sleeper.
In this standard mechanical tests are defined which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition controls are placed on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage.

This European Standard specifies the requirements for the approval of a process wherein a rail of one profile has part of its length forged to a different profile, together with the requirements for subsequent forging production and product acceptance.
This European Standard applies to new railway rails according to EN 13674 1, and to switch and crossing rails used in conjunction with railway rails 46 kg/m and above according to EN 13674 2, to be welded or fish plated to make up switch rails or transition rails intended for use on railway infrastructures.

EN 16431 defines technical criteria and control procedures which are satisfied by hollow sleepers and bearers used in ballasted track with Vignole rails. The hollow sleepers and bearers designed for ballasted track can also be used in ballastless track. In this case, the requirements are defined by the customer.

ISO 12856-1:2014 specifies the characteristics of plastic and reinforced plastic materials to be used in the manufacturing of railway sleepers. It is applicable to the sleepers and parts of sleepers to be installed in tracks with or without ballast. Examples of different types of plastic and reinforced sleepers are given in an annex.

This European Standard specifies the minimum technical requirements and the tolerances for the acceptance of works on ballasted track situated on plain line and on switches and crossings and rail expansion devices, as part of the track, for 1 435 mm and wider track gauge railways, concerning construction of new track, track renewal and track maintenance. More particularly, this standard gives the requirements for the documentation of work parameters, for the tolerances for relative track geometry and absolute track position and for the acceptance procedures. This standard does not deal with contractual and legal aspects and it does not cover either works related to reprofiling the railhead nor the associated measurements, except for some measurements related to safety, since these works are covered by other parts of EN 13231 series. Related works, e.g. platform reconstruction, formation, drainage, level crossings are not covered by this standard.

This part of the European Standard specifies the minimum requirements that shall be met by measuring systems fitted on track recording 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 recording trolleys and manually operated devices to measure track geometry.
It applies to all track geometry measuring systems fitted to track recording trolleys and manually operated devices after the date of implementation of this standard.

This part of this European Standard covers the following subjects:
- geometric design principles for wheel guidance;
-  definition of basic limits of supply;
- applied forces and their adequate support;
- tolerance levels.
These are illustrated herein by application to a turnout. The main switch and crossing components are represented in turnouts and the principles used in turnouts apply equally to more complex layouts.

The scope of this part is:
-   to describe the design process of switches and crossings, and the use of the other parts of this standard;
-   to define the main criteria to be taken into account during the design of the layout, including the safety and functional dimensions as well as geometrical and material aspects;
-   to define the main criteria to be verified during the design approval;
-   to define the geometrical and non-geometrical acceptance criteria for inspection of layouts assembled both in the fabrication plant and at track site in case of layouts that are delivered non or partially assembled or in a "kit" form;
-   to determine the limits of supply;
-   to define the minimum requirements for traceability.
This European Standard applies only to layouts that are assembled in the manufacturing plant or that are assembled for the first time at trackside.
Other aspects such as installation and maintenance also influence performance; these are not considered as part of this European Standard.
