This document is applicable to fastening systems, in categories A –E as specified in EN 13481 1:2012, 3.1 for use in switches and crossings. It is also provides guidance on evaluating fastening systems for check rails, expansion devices and insulated rail joints whether in switches and crossings or in plain line. The document applies to five categories of fastenings used in tracks with respective maximum axle loads and minimum curve radii as shown in Table 1.

The requirements apply to fastening systems for rail sections included in the EN 13674 series of standards (excluding 49E4).
This document is not applicable to fastening systems for other rail sections or rigid fastening systems used on running rails.
This document is for type approval of complete fastening systems.

This document is applicable to fastening systems, in categories A –E as specified in EN 13481-1:2012, 3.1 for use on wood or polymeric composite sleepers in ballasted or ballastless track, including track on open deck bridges, with respective maximum axle loads, and minimum curve radii as shown in Table 1.

The requirements apply to:
− fastening systems which act on the foot and/or web of the rail including direct fastening systems and indirect fastening systems;
− fastening systems for rail sections included in EN 13674-1:2011+A1:2017 (excluding 49E4) or EN 13674-4:2019.
This document is not applicable to fastening systems for other rail sections, rigid fastening systems, special fastening systems used at bolted joints or glued joints or special low clamping force fastenings used to mitigate track-bridge interaction effects.
This document is for type approval of complete fastening systems.

This document is applicable to fastening systems, in categories A –D as specified in EN 13481-1:2012, 3.1 for attaching rails to the uppermost surface of concrete or steel elements in ballastless tracks, including tracks on open deck bridges, and for embedded rails in ballastless tracks, for respective maximum axle loads and minimum curve radii in accordance with Table 1.

The requirements apply to:
− fastening systems which act on the foot and/or web of the rail including direct fastening systems and indirect fastening systems;
− fastening systems for rail sections included in EN 13674-1 (excluding 49E4) or EN 13674-4.
This document is not applicable to:
− fastening systems for other rail sections
− fastening systems for use on wood or polymer composite sleepers used in ballastless track, performance requirements for which are included in EN 13481-3
− rigid fastening systems
This document is not applicable to fastening systems for other rail sections, rigid fastening systems, special fastening systems used at bolted joints or glued joints or special low clamping force fastenings used to mitigate track-bridge interaction effects.
This document is for type approval of complete fastening systems. In track forms in which there are rail seat blocks or sleepers mounted in “boots” the concrete element and its resilient support are considered to be parts of the elastic fastening system. If the track form includes floating slabs, (i.e. resiliently supported concrete elements with more than one fastening per rail) those concrete elements and their resilient supports are considered to be parts of the ballastless track and not of the fastening system.

This document specifies rules and limits for track alignment design parameters, including alignments within switches and crossings. Several of these limits are functions of speed. Alternatively, for a given track alignment, it specifies rules and limits that determine permissible speed with regards to track alignment.
This document applies to urban or suburban rail networks for passenger services not integrated with the national network.
Sections of urban or suburban rail networks integrated in the national rail networks are not covered by this document. They are covered by EN 13803 (or for nominal track gauges smaller than 1 435 mm by national alignment rules).
For the purpose of this document, urban or suburban rail networks include:
— Networks designed for own right of way and segregated from general road and pedestrian traffic,
and
— Networks (partly) not segregated from general road and pedestrian traffic, with shared lanes.
This document applies to rail systems with steel wheels running on steel vignole or grooved rails. Rail systems with specific construction issues (e.g. rack railways, funicular railways and other types of cable drawn rail systems) are not covered by this document.
This document defines the parameters, rules and limits for nominal track gauges of 1 435 mm and 1 000 mm with permissible speeds up to 120 km/h. For other nominal track gauges, this document defines conversion rules which shall be used to define the limits.
